+## [2.4.0-beta.1]
+
+> Released 2021/03/23
+
+This is a _beta_ pre-release of the upcoming Kong 2.4 series. Since 2.4 is a
+minor release there are no breaking changes with respect to the 2.x series.
+Please note that this is a feature-frozen release, up to the 2.4.0 release only
+bug fixes will be added.
+
+### Dependencies
+
+- :warning: For Kong 2.4, the required OpenResty version has been bumped to
+  [1.19.3.1](http://openresty.org/en/changelog-1019003.html), and the set of
+  patches included has changed, including the latest release of
+  [lua-kong-nginx-module](https://github.com/Kong/lua-kong-nginx-module).
+  If you are installing Kong from one of our distribution
+  packages, you are not affected by this change.
+
+**Note:** if you are not using one of our distribution packages and compiling
+OpenResty from source, you must still apply Kong's [OpenResty
+patches](https://github.com/Kong/kong-build-tools/tree/master/openresty-build-tools/patches)
+(and, as highlighted above, compile OpenResty with the new
+lua-kong-nginx-module). Our [kong-build-tools](https://github.com/Kong/kong-build-tools)
+repository will allow you to do both easily.

+  Plane plugins. [6932](https://github.com/Kong/kong/pull/6932)
+
+##### PDK
+
+- Beta release of Protobuf plugin communication protocol, which can be used in
+  place of MessagePack to communicate with non-Lua plugins.
+  [6941](https://github.com/Kong/kong/pull/6941)
+
+##### Plugins
+
+- zipkin: support for Jaeger style uber-trace-id headers.

+  Thanks [nvx](https://github.com/nvx) for the patch!

+
+### Fixes
+
+##### Core
+
+- Changed default values and validation rules for plugins that were not
+  well-adjusted for dbless or hybrid modes.
+  [6885](https://github.com/Kong/kong/pull/6885)
+- Topological sort now prioritizes core, avoiding problems when plugin entities
+  use core entities but don't explicitly depend on them.
+  [6880](https://github.com/Kong/kong/pull/6880)
+- If needed, `Host` header is now updated between balancer retries, using the
+  value configured in the correct upstream entity.
+  [6796](https://github.com/Kong/kong/pull/6796)
+- Schema validations now log more descriptive error messages when types are
+  invalid. [6593](https://github.com/Kong/kong/pull/6593)
+  Thanks [WALL-E](https://github.com/WALL-E) for the patch!
+- Kong now ignores tags in Cassandra when filtering by multiple entities, which
+  is the expected behavior and the one already existent when using Postgres
+  databases. [6931](https://github.com/Kong/kong/pull/6931)
+- `Upgrade` header is not cleared anymore when response `Connection` header
+  contains `Upgrade`. [6929](https://github.com/Kong/kong/pull/6929)
+- Accept fully-qualified domain names ending in dots.
+  [6864](https://github.com/Kong/kong/pull/6864)
+- Kong does not try to warmup upstream names when warming up DNS entries.
+  [6891](https://github.com/Kong/kong/pull/6891)
+- Migrations order is now guaranteed to be always the same.
+  [6901](https://github.com/Kong/kong/pull/6901)
+- Buffered responses are disabled on connection upgrades.
+  [6902](https://github.com/Kong/kong/pull/6902)
+
+##### PDK
+
+- Now Kong does not leave plugin servers alive after exiting and does not try to
+  start them in the unsupported stream subsystem.
+  [6849](https://github.com/Kong/kong/pull/6849)
+
+##### Plugins
+
+- oauth2: better handling more cases of client invalid token generation.
+  [6594](https://github.com/Kong/kong/pull/6594)
+  Thanks [jeremyjpj0916](https://github.com/jeremyjpj0916) for the patch!
+- zipkin: the w3c parsing function was returning a non-used extra value, and it
+  now early-exits. [100](https://github.com/Kong/kong-plugin-zipkin/pull/100)
+  Thanks [nvx](https://github.com/nvx) for the patch!
