These pages cover the 3.x versions of the Couchbase C SDK. For release notes, download links, and installation methods for 2.10 and earlier releases of the Couchbase C Client, please see the [2.x C Release Notes & Download Archive](#2.10@c-sdk::sdk-release-notes.adoc). ## [](#platform-support-and-installation)Platform support and installation The Couchbase C SDK can be installed via apt or yum repositories on GNU/Linux; homebrew on Mac OS X; and [binary archives for Microsoft Windows](#install-windows). It may also be [built from source](https://github.com/couchbase/libcouchbase) on any of the platforms mentioned above, and more. ## [](#installing-on-gnulinux)Installing on GNU/Linux The various Linux distributions contain the following packages: * `**libcouchbase3**`: The core library package. * `**libcouchbase-dev**` (or `**libcouchbase-devel**`): The development package, required if building SDKs which depend on the C SDK. * `**libcouchbase3-tools**`: The command line utilities (`**cbc**` and others). * `**libcouchbase3-libevent**`: Optional but recommended component for I/O performance. Can also be used to integrate with libevent (see [Asynchronous Programming](../howtos/concurrent-async-apis.md)). * `**libcouchbase3-libev**`: Optional, for use with applications that make use of event loop integration with libev (see [Asynchronous Programming](../howtos/concurrent-async-apis.md)). To install the C SDK from a static binary package or by manually configuring the repositories, you can use the following procedures. ### [](#configuring-yum-repositories-centos-redhat)Configuring yum repositories (CentOS, Redhat) This section assumes you know how to add an external [yum](http://yum.baseurl.org/) repository and Linux quick start explains the steps it will perform on your distribution. To configure the repository: 1. Find the appropriate repository location for your distribution in the following table. | Version | Architecture | Repository | | ------------------- | ------------ | ------------------------------------------------------------------- | | Amazon Linux 2023 | 64-bit | https://packages.couchbase.com/clients/c/repos/rpm/amzn2023/x86\_64 | | Amazon Linux 2 | AArch64 | https://packages.couchbase.com/clients/c/repos/rpm/amzn2/aarch64 | | Amazon Linux 2 | 64-bit | https://packages.couchbase.com/clients/c/repos/rpm/amzn2/x86\_64 | | Enterprise Linux 8 | 64-bit | https://packages.couchbase.com/clients/c/repos/rpm/el8/x86\_64 | | Enterprise Linux 9 | 64-bit | https://packages.couchbase.com/clients/c/repos/rpm/el9/x86\_64 | | Enterprise Linux 10 | 64-bit | https://packages.couchbase.com/clients/c/repos/rpm/el10/x86\_64 | 1. Create a `couchbase.repo` file in your `/etc/yum.repos.d` directory. It should look similar to the following: ```toml [couchbase] enabled = 1 name = libcouchbase package for centos10 x86_64 baseurl = https://packages.couchbase.com/clients/c/repos/rpm/el10/x86_64 gpgcheck = 1 gpgkey = https://packages.couchbase.com/clients/c/repos/rpm/couchbase.key ``` ### [](#configuring-apt-repositories-debian-ubuntu)Configuring APT repositories (Debian, Ubuntu) This section assumes some knowledge of [apt](https://wiki.debian.org/Apt) and Linux quick start explains the steps it will perform on your distribution. To configure the repository: 1. Download the Couchbase GPG key from 2. Add the key to the list of trusted package keys. Use the `apt-key add` command. For example, `apt-key add couchbase.key`. 3. Create a couchbase.list file in `/etc/apt/sources.list.d`. The file should contain the repository for your distribution. Repositories are available for the following distributions: | Distribution | Repository Entry | | ---------------------- | -------------------------------------------------------------------------------------- | | Ubuntu 22.04 ("jammy") | deb https://packages.couchbase.com/clients/c/repos/deb/ubuntu2204 jammy jammy/main | | Ubuntu 24.04 ("noble") | deb https://packages.couchbase.com/clients/c/repos/deb/ubuntu2404 noble noble/main | | Debian 11 ("bullseye") | deb https://packages.couchbase.com/clients/c/repos/deb/debian11 bullseye bullseye/main | | Debian 12 ("bookworm") | deb https://packages.couchbase.com/clients/c/repos/deb/debian12 bookworm bookworm/main | Note that only Ubuntu LTS (long term support) releases are supported. You may try to use an LTS repository for a non-LTS version, but success is not guaranteed. Now that you have the repository configured, refresh the cache then check to see that you have been successful: ```console $ sudo apt update ``` ```console $ sudo apt search libcouchbase ``` You should see something like: ```console libcouchbase-dbg - library for the Couchbase protocol, debug symbols libcouchbase-dev - library for the Couchbase protocol, development files libcouchbase3 - library for the Couchbase protocol, core files libcouchbase3-libev - library for the Couchbase protocol (libev backend) libcouchbase3-libevent - library for the Couchbase protocol (libevent backend) libcouchbase3-tools - library for the Couchbase protocol ``` Now, install `libcouchbase3`, and any other packages that you need for development: ```console $ sudo apt install libcouchbase3 libcouchbase-dev libcouchbase3-tools libcouchbase-dbg libcouchbase3-libev libcouchbase3-libevent ``` For CentOS and Red Hat, the equivalent commands are: ```console $ sudo yum check-update ``` ```console $ sudo yum search libcouchbase ``` ### [](#installing-binary-packages-without-a-repository)Installing binary packages without a repository You can install standalone packages by downloading a tarball containing the necessary binary packages for your platform. **Installing RPMs** The following commands show steps to execute on **CentOS 7** box. For other RPM-based distributions — such as Amazon Linux 2023 — the steps are the same or similar. ```console $ curl -O https://packages.couchbase.com/clients/c/libcouchbase-3.3.12_centos7_x86_64.tar ``` ```console $ tar xf libcouchbase-3.3.12_centos7_x86_64.tar ``` ```console $ cd libcouchbase-3.3.12_centos7_x86_64 ``` ```console $ sudo yum install -y libcouchbase3{-tools,-libevent,}-3.3.12*.rpm libcouchbase-devel-*.rpm ``` ```console > ... > Installed: > libcouchbase-devel.x86_64 0:3.3.12-1.el7 > libcouchbase3.x86_64 0:3.3.12-1.el7 > libcouchbase3-libevent.x86_64 0:3.3.12-1.el7 > libcouchbase3-tools.x86_64 0:3.3.12-1.el7 > ... > > Complete! ``` **Installing DEBs** The following commands show steps to execute on **Debian 10 (buster)** box, see table below for other DEB-based distributions. ```console $ curl -O https://packages.couchbase.com/clients/c/libcouchbase-3.3.1_debian10_buster_amd64.tar ``` ```console $ tar xf libcouchbase-3.3.1_debian10_buster_amd64.tar ``` ```console $ cd libcouchbase-3.3.1_debian10_buster_amd64 ``` ```console $ sudo apt install libevent-core-2.1 ``` ```console $ sudo dpkg -i libcouchbase3{-tools,-libevent,}_3.3.1*.deb libcouchbase-dev*.deb ``` ```console $ sudo dpkg -i libcouchbase3{-tools,-libevent,}_3.2.0*.deb libcouchbase-dev*.deb > Selecting previously unselected package libcouchbase3-tools. > (Reading database ... 7177 files and directories currently installed.) > Preparing to unpack libcouchbase3-tools_3.2.0-1_amd64.deb ... > Unpacking libcouchbase3-tools (3.2.0-1) ... > Selecting previously unselected package libcouchbase3-libevent:amd64. > Preparing to unpack libcouchbase3-libevent_3.2.0-1_amd64.deb ... > Unpacking libcouchbase3-libevent:amd64 (3.2.0-1) ... > Selecting previously unselected package libcouchbase3:amd64. > Preparing to unpack libcouchbase3_3.2.0-1_amd64.deb ... > Unpacking libcouchbase3:amd64 (3.2.0-1) ... > Selecting previously unselected package libcouchbase-dev:amd64. > Preparing to unpack libcouchbase-dev_3.2.0-1_amd64.deb ... > Unpacking libcouchbase-dev:amd64 (3.2.0-1) ... > Setting up libcouchbase3:amd64 (3.2.0-1) ... > Setting up libcouchbase-dev:amd64 (3.2.0-1) ... > Setting up libcouchbase3-libevent:amd64 (3.2.0-1) ... > Setting up libcouchbase3-tools (3.2.0-1) ... > Processing triggers for libc-bin (2.28-10) ... ``` ## [](#installation-from-source)Installation from source You may install the library from source either by downloading a source archive, or by checking out the [git repository](https://github.com/couchbase/libcouchbase). Follow the instructions in the archive's [README](https://github.com/couchbase/libcouchbase/blob/master/README.markdown) for further instructions. ## [](#installation-on-mac-os-x)Installation on Mac OS X To install the library on Mac OS X, first install the de-facto package manager for OS X: [homebrew](https://brew.sh/). Once _homebrew_ is configured: ```console $ brew update # get list of latest packages ``` ```console $ brew install libcouchbase ``` To install development files and command line tools on Mac OS, follow the instructions for [installing from source](https://github.com/couchbase/libcouchbase/blob/master/README.markdown#building-on-unix-like-systems). ## [](#install-windows)Windows Installation Windows binary packages can be found as downloads for each version listed below. Included are the header files, release and debug variants of the DLLs and import libraries, and release and debug variants of the command line tools. Note that the C SDK does not have any preferred installation path, and it is up to you to determine where to place `libcouchbase.dll`. Be sure to select the proper package for the compiler and architecture your application is using. Binaries are linked from the release notes page for each libcouchbase release — we strongly recommend [downloading the latest release](#latest-release). > [!NOTE] > If there are no binaries available for your Visual Studio version, then using a binary from any other Visual Studio version is _likely_ to work. Most of the issues related to mixing Visual Studio binary versions involve changing and incompatible C APIs or incompatible C Runtime (CRT) objects and functions. Since the Couchbase C SDK does not expose a C API, and since it does not directly expose any CRT functionality, it should be safe for use so long as your application can link to the library at compile-time. The windows runtime linker will ensure that each binary is using the appropriate version of the Visual C Runtime (`MSVCRT.DLL`). If for some reason you cannot use any of the prebuilt Windows binaries, follow the instructions in [_installation from source_ (above)](#installation-from-source) to build on Windows. ## [](#verifying-installed-package)Verifying Installed Package The easiest way to verify installed package is to check its version using cbc tools. It requires package **libcouchbase3-tools** installed on Linux systems, for Windows **cbc.exe** included in the zip archive. To verify the client run **cbc version** (**cbc.exe version** on Windows). It shows version along with git commit numbers. Then it prints default directory where IO plugins installed and enumerates the currently installed and available plugins. After that it reports whether OpenSSL linked to this particular version of libcouchbase, and displays the version number if it is accessible. ```console $ cbc version cbc: Runtime: Version=3.2.0, Changeset=c712686af5825f2f05c89112e555cd09906aa727 Headers: Version=3.2.0, Changeset=c712686af5825f2f05c89112e555cd09906aa727 Build Timestamp: 2021-07-20 09:31:59 Default plugin directory: /usr/lib64/libcouchbase IO: Default=libevent, Current=libevent, Accessible=libevent,select SSL Runtime: OpenSSL 1.1.1g FIPS 21 Apr 2020 SSL Headers: OpenSSL 1.1.1g FIPS 21 Apr 2020 Snappy: 1.1.8 Tracing: SUPPORTED System: Linux-4.15.0-91-generic; x86_64 CC: GNU 8.4.1; -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -fno-strict-aliasing -ggdb3 -pthread CXX: GNU 8.4.1; -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic -fasynchronous-unwind-tables -fstack-clash-protection -fcf-protection -fno-strict-aliasing -ggdb3 -pthread ``` ## [](#latest-release)C SDK 3.3 Releases We always recommend using the latest version of the SDK — it contains all of the latest security patches and support for new and upcoming features. All patch releases for each dot minor release should be API compatible, and safe to upgrade; any changes to expected behavior are noted in the release notes that follow. ### [](#version-3-3-19-13-may-2026)Version 3.3.19 (13 May 2026) [API Reference](https://docs.couchbase.com/sdk-api/couchbase-c-client-3.3.19/index.html) This is a maintenance release. * [CCBC-1685](https://issues.couchbase.com/browse/CCBC-1685): Added `lcb_trim_memory()` to release cached pool memory. Long-lived instances that occasionally burst and then idle retain the peak working set of every pipeline's internal allocator until `lcb_destroy()`. In memory-constrained environments (containers, tight cgroup limits) this plateau is easily mistaken for a leak and can trigger the OOM killer once several instances are stacked in one process. The new API releases the backing buffers of cached blocks without touching in-flight operations or connections. Intended for periodic invocation from an application's idle tick when RSS approaches a configured limit. * [CCBC-1702](https://issues.couchbase.com/browse/CCBC-1702): Requeue operations when the vBucket map briefly has no master. During failover, rebalance, and the moment a new configuration is being installed the vbmap can transiently show no master for a vBucket. Previously such operations failed immediately with `LCB_ERR_NO_MATCHING_SERVER`; they are now retried until the operation deadline expires, matching the contract customers expect during topology changes. Opt-out remains available via `retry=missingnode=0`. This change also closes several latent use-after-free races on the configuration-replacement path that the longer retry window made reachable. * [CCBC-1699](https://issues.couchbase.com/browse/CCBC-1699), [CCBC-1695](https://issues.couchbase.com/browse/CCBC-1695), [CCBC-1694](https://issues.couchbase.com/browse/CCBC-1694): Fixed TLS and `libuv` crashes, and hangs around instance teardown and live configuration updates. Pre-fix symptoms included `SIGABRT` in the SSL context destructor on Couchbase Server 7.6 and 6.6, a deadlock in `lcb_destroy()` that prevented async-destroy callbacks from firing, and a use-after-free crash during rebalance and failover against CBS 6.0.x under TLS. The libuv I/O plugin now caps its teardown drain and force-closes orphaned timers and sockets so `lcb_destroy_io_ops()` no longer hangs or asserts on `uv_loop_close`. * [CCBC-1686](https://issues.couchbase.com/browse/CCBC-1686), [CCBC-1687](https://issues.couchbase.com/browse/CCBC-1687), [CCBC-1692](https://issues.couchbase.com/browse/CCBC-1692): Hardened the `conn-state-invalidated` error path. A server-side error carrying this errmap attribute (e.g. `EINTERNAL` 0x84) could leave the client exposed to a destroy/refresh race that crashed on Windows IOCP and was a latent use-after-free on Linux. Configuration providers are now paused synchronously at the start of `lcb_destroy()`, and an inverted guard in the error handler that could deliver `LCB_SUCCESS` to user callbacks (or clobber a more specific status with `LCB_ERR_GENERIC`) has been corrected. * [CCBC-1688](https://issues.couchbase.com/browse/CCBC-1688): Fixed use-after-free in the threshold-logging tracer. Host and port tags attached to a span used to point into the owning socket's connection info, which could be freed before the span was finished — for example when a sockpool entry was torn down by its timer while the outer HTTP/View request was still draining. The tracer now copies these short strings. * [CCBC-1684](https://issues.couchbase.com/browse/CCBC-1684): Preserve the `deadline >= start` invariant when an operation is re-stamped at flush time. With `LCB_CNTL_RESET_TIMEOUT_ON_WAIT` enabled and a short per-op timeout, the flush callback could produce a packet with `start > deadline` and abort the process via an assertion on the next `lcb_wait()`. Both fields are now rebased to flush time, preserving the remaining timeout budget. * Fixed packet replacement and memory management in the retry queue. When a collection is being flushed and packets are renewed in place, the old packet's bytes can still be referenced by the netbuf PDU queue or an in-flight kernel write. The new `MCREQ_F_REPLACED` flag lets the retry path safely replace such packets without freeing memory that is still on the wire. * [CCBC-1693](https://issues.couchbase.com/browse/CCBC-1693): Avoid copying the cached collection path on every KV response. `CollectionCache::id_to_name` now returns a stable reference into the cache instead of a fresh `std::string`, eliminating a per-reply allocation for collection paths longer than the small-string optimisation threshold. * [CCBC-1682](https://issues.couchbase.com/browse/CCBC-1682): Fixed Analytics discovery with Alternate Addresses. When connecting to Couchbase Operational or Enterprise Analytics using `LCB_TYPE_CLUSTER`, the client used `/poolsStreaming/default`, which returns a legacy configuration without `nodesExt` and triggers the 2.x parser fallback. As a result the Analytics service was not discovered, alternate addresses were ignored, and callers saw `LCB_ERR_UNSUPPORTED_OPERATION`. The cluster-level HTTP bootstrap now uses `/pools/default/nodeServicesStreaming`. * [CCBC-1678](https://issues.couchbase.com/browse/CCBC-1678): Deprecate the Views (Map-Reduce) API in public headers. Couchbase Server 7.0 deprecated the Views service in favour of the Query Service (SQL++). All public view entry points now emit `-Wdeprecated-declarations` at call sites with a guiding message. ABI is preserved; existing binaries continue to link and run. Translation units that legitimately use the Views API can opt out by predefining `LCB_DEPRECATE_VIEWS(X)` before including `couchbase.h`. * Honor `op→trytime` strictly when flushing scheduled retries. The previous 5 ms early-fire window could let a retry land below the errmap retry-spec's documented "wait at least N ms before the first retry" floor, observable on slower CI runners. * [CCBC-1689](https://issues.couchbase.com/browse/CCBC-1689), [CCBC-1690](https://issues.couchbase.com/browse/CCBC-1690), [CCBC-1691](https://issues.couchbase.com/browse/CCBC-1691): Stabilised the test suite around failover/replica-read, libuv-specific timer races, and slow Windows Debug bootstrap. SDK behaviour is unchanged. #### [](#downloads)Downloads | Platform | Architecture | File | | ----------------------------- | ------------ |

(10 September 2025) [API Reference](https://docs.couchbase.com/sdk-api/couchbase-c-client-3.3.18/index.html) This is a maintenance release. * [CCBC-1672](https://issues.couchbase.com/browse/CCBC-1672): Fixed a protocol violation on new connections. In certain cases, extra bytes could be sent at the start of a new connection. Most of the time, this caused the server to drop the connection and the client would reconnect automatically, so users did not notice. However, in rare cases the server would accept the data as valid, leading to protocol issues. This has been corrected so that invalid data is properly discarded and connections stay consistent. * [CCBC-1671](https://issues.couchbase.com/browse/CCBC-1671): Sending requests to all replica nodes for strategy "ANY". This change makes implementation of `get_any_replica` behave the same way as other SDKs. * The old behavior: "get any replica" would send requests sequentially one by one. So that the next request will be dispatched only when previous fails. * The new behavior: "get any replica" send requests to active and replica nodes simulaneously and returns only first response to the user, discarding everything else. * [CCBC-1669](https://issues.couchbase.com/browse/CCBC-1669): `get_all_replicas` will no longer fail if all possible nodes are not available — and now only fail if no nodes are available. * [CCBC-1668](https://issues.couchbase.com/browse/CCBC-1668): The client has stopped assuming that missing active node means none available for a replica read. With this change reading a replica will be more reliable during failover and rebalance events. * [CCBC-1667](https://issues.couchbase.com/browse/CCBC-1667): No longer scheduling a config update during instance termination. This change fixes use-after-free during `lcb_destroy`. * [CCBC-1674](https://issues.couchbase.com/browse/CCBC-1674): No longer using non-owning spans to release memory with `NETBUF_LIBC_PROXY`. This fixes use-after-free for build with `NETBUF_LIBC_PROXY` when snappy compression is enabled. This is a special build when caching allocator is replaced with just libc malloc. It is used only during development and testing, and never enabled in production. * [CCBC-1673](https://issues.couchbase.com/browse/CCBC-1673): No longer returning block with `deallocs` as free in `find_free_block` of the `netbuf` subsystem. * Raised minimum `cmake` version to 3.17. * Log local port to make it easier to correlate with the Server logs. #### [](#downloads-2)Downloads | Platform |

June 2025) [API Reference](https://docs.couchbase.com/sdk-api/couchbase-c-client-3.3.17/index.html) This is a maintenance release. * [CCBC-1666](https://issues.couchbase.com/browse/CCBC-1666): Configuration manager was not correctly handling `LCB_ERR_REQUEST_CANCELED` during instance destruction. With completion-based IO (`libuv`, Windows `IOCP`), the library could try to schedule a configuration update on an already deallocated pipeline and cause a use-after-free condition. To fix the issue, the configuration manager has now been updated to handle `LCB_ERR_REQUEST_CANCELED` and return without issuing a new request. #### [](#downloads-3)Downloads | Platform | Architecture | File | | ----------------------------- | ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------- | | Checksums | Any | [libcouchbase-3.3.17.sha256sum](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17.sha256.txt) | | Source Archive | Any | [libcouchbase-3.3.17.tar.gz](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17.tar.gz) | | Amazon Linux 2023 | x86\_64 | [libcouchbase-3.3.17\_amzn2023\_x86\_64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Famzn2023%5Fx86%5F64.tar) | | Amazon Linux 2 | x86\_64 | [libcouchbase-3.3.17\_amzn2\_x86\_64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Famzn2%5Fx86%5F64.tar) | | Enterprise Linux 8 | x86\_64 | [libcouchbase-3.3.17\_rhel8\_x86\_64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Frhel8%5Fx86%5F64.tar) | | Enterprise Linux 8 | aarch64 | [libcouchbase-3.3.17\_rhel8\_aarch64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Frhel8%5Faarch64.tar) | | Enterprise Linux 9 | x86\_64 | [libcouchbase-3.3.17\_rhel9\_x86\_64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Frhel9%5Fx86%5F64.tar) | | Enterprise Linux 9 | aarch64 | [libcouchbase-3.3.17\_rhel9\_aarch64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Frhel9%5Faarch64.tar) | | Ubuntu 22.04 (jammy) | x86\_64 | [libcouchbase-3.3.17\_ubuntu2204\_jammy\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fubuntu2204%5Fjammy%5Famd64.tar) | | Ubuntu 22.04 (jammy) | aarch64 | [libcouchbase-3.3.17\_ubuntu2204\_jammy\_arm64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fubuntu2204%5Fjammy%5Farm64.tar) | | Ubuntu 24.04 (noble) | x86\_64 | [libcouchbase-3.3.17\_ubuntu2404\_noble\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fubuntu2404%5Fnoble%5Famd64.tar) | | Ubuntu 24.04 (noble) | aarch64 | [libcouchbase-3.3.17\_ubuntu2404\_noble\_arm64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fubuntu2404%5Fnoble%5Farm64.tar) | | Debian 11 (bullseye) | x86\_64 | [libcouchbase-3.3.17\_debian11\_bullseye\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fdebian11%5Fbullseye%5Famd64.tar) | | Debian 11 (bullseye) | aarch64 | [libcouchbase-3.3.17\_debian11\_bullseye\_arm64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fdebian11%5Fbullseye%5Farm64.tar) | | Debian 12 (bookworm) | x86\_64 | [libcouchbase-3.3.17\_debian12\_bookworm\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fdebian12%5Fbookworm%5Famd64.tar) | | Debian 12 (bookworm) | aarch64 | [libcouchbase-3.3.17\_debian12\_bookworm\_arm64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fdebian12%5Fbookworm%5Farm64.tar) | | Visual Studio 2015 (VC14) | x86\_64 | [libcouchbase-3.3.17\_vc14\_amd64.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fvc14%5Famd64.zip) | | Visual Studio 2017 (VC15) | x86\_64 | [libcouchbase-3.3.17\_vc15\_amd64.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fvc15%5Famd64.zip) | | Visual Studio 2019 (VC16) | x86\_64 | [libcouchbase-3.3.17\_vc16\_amd64.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fvc16%5Famd64.zip) | | Visual Studio 2022 (VC17) | x86\_64 | [libcouchbase-3.3.17\_vc17\_amd64.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fvc17%5Famd64.zip) | | Visual Studio 2015 TLS (VC14) | x86\_64 | [libcouchbase-3.3.17\_vc14\_amd64\_openssl3.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fvc14%5Famd64%5Fopenssl3.zip) | | Visual Studio 2017 TLS (VC15) | x86\_64 | [libcouchbase-3.3.17\_vc15\_amd64\_openssl3.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fvc15%5Famd64%5Fopenssl3.zip) | | Visual Studio 2019 TLS (VC16) | x86\_64 | [libcouchbase-3.3.17\_vc16\_amd64\_openssl3.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fvc16%5Famd64%5Fopenssl3.zip) | | Visual Studio 2022 TLS (VC17) | x86\_64 | [libcouchbase-3.3.17\_vc17\_amd64\_openssl3.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.17%5Fvc17%5Famd64%5Fopenssl3.zip) | ### [](#version-3-3-16-01-june-2025)Version 3.3.16 (01 June 2025) [API Reference](https://docs.couchbase.com/sdk-api/couchbase-c-client-3.3.16/index.html) This is a maintenance release and includes several bugs fixes and stability improvements.

(12 November 2024) [API Reference](https://docs.couchbase.com/sdk-api/couchbase-c-client-3.3.14/index.html) * [CCBC-1653](https://jira.issues.couchbase.com/browse/CCBC-1653): Libcouchbase now correctly honors the timeout setting for Analytics query, when it is changed to a non-default value. * [CCBC-1651](https://jira.issues.couchbase.com/browse/CCBC-1651): Previously, the library did not release memory of the packets that never got a chance to be flushed to the network buffer, if libcouchbase was still trying to connect sockets. This has been fixed, so that purged packets get their memory released, it thus fixes a memory leak in case of network issues. * [CCBC-1646](https://jira.issues.couchbase.com/browse/CCBC-1646): Implemented Server groups for replica reads — allow to restrict replica set to a selected server group. This feature allows to implement network optimization when traffic cost between server groups is higher than in the local group. In this case the application might select preferred server group in the connection options, and later opt-in for local operations during replica reads. * [CCBC-1555](https://jira.issues.couchbase.com/browse/CCBC-1555): Removed extra prefix in tapset probes. * [CCBC-1598](https://jira.issues.couchbase.com/browse/CCBC-1598): Fixed documentation issues for cbc tools. * Fixed tests on 7.6 Server. #### [](#downloads-6)Downloads | Platform | Architecture | File | | ----------------------------- | ------------ |

2024) [API Reference](https://docs.couchbase.com/sdk-api/couchbase-c-client-3.3.12/index.html) * [CCBC-1636](https://issues.couchbase.com/browse/CCBC-1636): The library was not deallocating the old packet after setting the collection ID field in the copy. `mcreq_renew_packet()` requires the caller to deallocate original copy, otherwise the memory will be only released by pipeline destructor. This has been addressed, and old packets are now deallocated when the collection ID is updated, freeing up memory. * [CCBC-1634](https://issues.couchbase.com/browse/CCBC-1634): Fixed the reporting of unresponsive nodes in `lcb_ping()`. * No longer retrying NOOP commands, as they might be routed to different pipeline, instead fail fast NOOPs to reflect network issues more precisely. * Now using pipeline address as ping entry identifier instead of socket address, as socket may not exist (not connected), owing to network failures. * `lcb_ping` must still now report, even when overall status is not `LCB_SUCCESS`, so `cbc-ping` should still try to print report instead of just printing overall status code. * [CCBC-1630](https://issues.couchbase.com/browse/CCBC-1630): Check collection id before storing packet to pipeline. Every time `check_collection_id()` is invoked, the caller should ensure that this function potentially is rewriting the packet, if it decides to insert/update an encoded collection ID.

[API Reference](https://docs.couchbase.com/sdk-api/couchbase-c-client-3.3.2/index.html) #### [](#bug-fixes)Bug Fixes * [CCBC-1559](https://issues.couchbase.com/browse/CCBC-1559): `cbc-n1qlback`: give time to IO loop in case of failure. In scenarios where all query nodes suddenly fail over and/or are removed from the cluster, all requests in `cbc-n1qlback` will start failing. Because libcouchbase knows that the latest config does not have any query nodes, it rejects all queries immediately. The single-threaded nature of libcouchbase does not allow the IO loop to run in background, and the code in the tool does not run `lcb_wait` in case of failure. As a fix, we run `lcb_tick_nowait` in case of failure, which is enough for libcouchbase to give IO loop a chance to check for any pending events and invoke corresponding callbacks. #### [](#improvements)Improvements * [CCBC-1552](https://issues.couchbase.com/browse/CCBC-1552): Libcouchbase may now be built with an external `jsoncpp` library. * [CCBC-1557](https://issues.couchbase.com/browse/CCBC-1557): Allow caching cluster-level configurations. The library will cache cluster-level configurations only if the `config_cache=` connection string option is set to directory (ends with '/' symbol), otherwise it will cache only buckets configurations (note that in this case the application should use unique cache name for each bucket, otherwise the library will ignore cache if the bucket name will not match). #### [](#downloads-18)Downloads | Platform | Architecture | File | | ----------------------------- | ------------ | -------------------------------------------------------------------------------------------------------------------------------------------------- | | Checksums | Any | [libcouchbase-3.3.2.sha256sum](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2.sha256sum) | | Source Archive | Any | [libcouchbase-3.3.2.tar.gz](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2.tar.gz) | | Amazon Linux 2 | aarch64 | [libcouchbase-3.3.2\_amzn2\_aarch64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Famzn2%5Faarch64.tar) | | Amazon Linux 2 | x86\_64 | [libcouchbase-3.3.2\_amzn2\_x86\_64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Famzn2%5Fx86%5F64.tar) | | Enterprise Linux 7 | x86\_64 | [libcouchbase-3.3.2\_centos7\_x86\_64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fcentos7%5Fx86%5F64.tar) | | Ubuntu 16.04 (xenial) | x86\_64 | [libcouchbase-3.3.2\_ubuntu1604\_xenial\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fubuntu1604%5Fxenial%5Famd64.tar) | | Ubuntu 18.04 (bionic) | x86\_64 | [libcouchbase-3.3.2\_ubuntu1804\_bionic\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fubuntu1804%5Fbionic%5Famd64.tar) | | Ubuntu 20.04 (focal) | x86\_64 | [libcouchbase-3.3.2\_ubuntu2004\_focal\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fubuntu2004%5Ffocal%5Famd64.tar) | | Debian 9 (stretch) | x86\_64 | [libcouchbase-3.3.2\_debian9\_stretch\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fdebian9%5Fstretch%5Famd64.tar) | | Debian 10 (buster) | x86\_64 | [libcouchbase-3.3.2\_debian10\_buster\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fdebian10%5Fbuster%5Famd64.tar) | | Debian 11 (bullseye) | x86\_64 | [libcouchbase-3.3.2\_debian11\_bullseye\_amd64.tar](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fdebian11%5Fbullseye%5Famd64.tar) | | Visual Studio 2015 (VC14) | x86\_64 | [libcouchbase-3.3.2\_vc14\_amd64.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fvc14%5Famd64.zip) | | Visual Studio 2017 (VC15) | x86\_64 | [libcouchbase-3.3.2\_vc15\_amd64.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fvc15%5Famd64.zip) | | Visual Studio 2019 (VC16) | x86\_64 | [libcouchbase-3.3.2\_vc16\_amd64.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fvc16%5Famd64.zip) | | Visual Studio 2015 TLS (VC14) | x86\_64 | [libcouchbase-3.3.2\_vc14\_amd64\_openssl.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fvc14%5Famd64%5Fopenssl.zip) | | Visual Studio 2017 TLS (VC15) | x86\_64 | [libcouchbase-3.3.2\_vc15\_amd64\_openssl.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fvc15%5Famd64%5Fopenssl.zip) | | Visual Studio 2019 TLS (VC16) | x86\_64 | [libcouchbase-3.3.2\_vc16\_amd64\_openssl.zip](https://packages.couchbase.com/clients/c/libcouchbase-3.3.2%5Fvc16%5Famd64%5Fopenssl.zip) | ### [](#version-3-3-1-25-may-2022)Version 3.3.1 (25 May 2022) Version 3.3.1 is the second release of the 3.3 series.

Instead, the operation is automatically retried until timeout. * [CBCC-1280](https://issues.couchbase.com/browse/CCBC-1280): Support for OpenTelemetry tracing. Tracing updated to allow for an external tracer that creates and finishes spans, adds tags, destroys spans. Also, spans now have the notion of being the 'outer' span. That is the span that has all the outer span tags, and is the one whose duration is used to determine whether or not the operation has exceeded the threshold if the ThresholdLoggingTracer is used. If you pass in a parent that is an outer span, you must call `lcbtrace_span_finish` yourself. When an operation begins, if there is no parent span passed in, or if there is but it isn't an 'outer' span, then the operation creates the outer span itself.
