+## 22.9.24 (Sept 24 2022)
+
+* 20 Major releases in a row? Nope, we switched to a new
+  [versioning scheme](https://github.com/google/flatbuffers/wiki/Versioning)
+  that is based on date.
+
+* Python supports fixed size arrays now (#7529).
+
+* Behavior change in how C++ object API uses `UnPackTo`. The original intent of
+  this was to reduce allocations by reusing an existing object to pack data
+  into. At some point, this logic started to merge the states of the two objects
+  instead of clearing the state of the packee. This change goes back to the
+  original intention, the packed object is cleared when getting data packed into
+  it (#7527).
+
+* Fixed a bug in C++ alignment that was using `sizeof()` instead of the intended
+  `AlignOf()` for structs (#7520).
+
+* C# has an
+  [offical Nuget package](https://www.nuget.org/packages/Google.FlatBuffers) now
+  (#7496).
+
+## 2.0.8 (Aug 29 2022)
+
+* Fix for `--keep-prefix` the was generating the wrong include statements for
+  C++ (#7469). The bug was introduced in 2.0.7.
+
+* Added the `Verifier::Options` option struct to allow specifying runtime
+  configuration settings for the verifier (#7489). This allows to skip verifying
+  nested flatbuffers, a on-by-default change that was introduced in 2.0.7. This
+  deprecates the existing `Verifier` constructor, which may be removed in a
+  future version.
+
+* Refactor of `tests/test.cpp` that lead to ~10% speedup in compilation of the
+  entire project (#7487).
+
