v5.6.3

• [BUGFIX] Fixes invalid Symbol#name usage for Ruby versions < 3.0 #297 by @rayz

v5.6.2

• [OTHER] Ruby versions 3.2 and 3.3 are now supported. [#291] by @gdubicki
• [IMPROVEMENT] Reduce memory allocations during tag and metric serialization. [#294] by @schlubbi
• [IMPROVEMENT] Avoid allocations when using delay_serialization. [#295] by @jhawthorn

v5.6.1

5.6.1 / 2023.09.07

• [IMPROVEMENT] Add support for IPv6 UDP connection. #280 by @kazwolfe

v5.6.0

5.6.0 / 2023.07.10

• [FEATURE] Add the delay_serialization option, allowing users to delay expensive serialization until a more convenient time, such as after an HTTP request has completed. In multi-threaded mode, it causes serialization to happen inside the sender thread. #271 by @pudiva and @BlakeWilliams

• [FEATURE] Also, support the sender_queue_size in single_thread mode, so that it can benefit from the new delay_serialization option. Messages are now queued (possibly unserialized) until sender_queue_size is reached or #flush is called. It may be set to Float::INFINITY, so that messages are indefinitely queued until an explicit #flush. #271 by @pudiva and @BlakeWilliams

• [IMPROVEMENT] Add support of DD_DOGSTATSD_URL for configuration through environment variable. Valid formats are: udp://some-host, udp://some-host:port and unix:///path/to/unix.sock. DD_DOGSTATSD_URL has priority on other environment vars (DD_AGENT_HOST, DD_DOGSTATSD_PORT and DD_DOGSTATSD_SOCKET) but does not throw an error if others are set, values are overridden instead. #278 by @remeh

• [BUGFIX] Fix NoMethodError when Datadog::Statsd is initialized without telemetry. #272 by @matthewshafer

v5.5.0

5.5.0 / 2022.06.01

• [FEATURE] Add distribution_time method to facilitate measuring timing of a yielded block. #248 by @jordan-brough

• [BUGFIX] Stop flush timer before closing the queue #257 by @abicky

• [IMPROVEMENT] Various warnings removed #258 by @abicky

• [OTHER] Remove unused rack dependency #260 by @remeh

v5.4.0

5.4.0 / 2022.03.01

• [IMPROVEMENT] Add a pre_sampled option to metric methods [#235][] by [@matthewshafer][]

• [OTHER] Ruby versions earlier than 2.1.0 are no longer supported. Ruby-2.0 was EOL as of 2016-02-24.

• [OTHER] Ruby versions 3.0 and 3.1 are now supported, including a fix for keyword arguments to StatsD#open. [#240][]

v5.3.3

5.3.3 / 2022.02.02

• [IMPROVEMENT] Add option "buffer_flush_interval" to flush buffered metrics [#231][] by [@abicky][]

• [IMPROVEMENT] Add Sender.queue_size limits to limit number of buffered metrics [#232][] by [@djmitche][]

• [IMPROVEMENT] The client can now be configured to use UDS via the DD_DOGSTATSD_SOCKET environment variable.
  This variable does not take precedence over any explicit parameters passed to the Statsd constructor.
  [#227][] by [@djmitche][]

5.3.2 / 2021.11.03

• [OTHER] add a warning message for the v5.x update on install #222 by @djmitche

v5.3.1 / 2021.10.21

• [OTHER] restore connection opening behavior from before 5.3.0 (connections not opened on client instantiation but on the first write instead) #214 by @remeh

v5.3.0 / 2021.10.06

• [ENHANCEMENT] Automatically re-allocate resources (e.g. background thread) if dogstatsd-ruby is used in an application using forks #205 by @remeh
  This will help in scenarios where applications are not handling cleanup/re-creation of the dogstatsd-ruby instances in forked processes. If you are an user of v4.x versions of dogstatsd-ruby and want to migrate to v5.x, please make sure to go through this section of the README and through the migration guide.

• [BUGFIX] Fix client telemetry in applications using forks #205 by @remeh

Please note that this version will emit a deprecation message if you are using ruby < 2.1: we plan to drop support for ruby 2.0 in a future minor release.
