+## [23.3.3 (Mar 3 2023)](https://github.com/google/flatbuffers/releases/tag/v23.3.3)
+
+* Refactoring of `flatc` generators to use an interface (#7797).
+
+* Removed legacy cmake support and set min to 3.8 (#7801).
+
+## [23.1.21 (Jan 21 2023)](https://github.com/google/flatbuffers/releases/tag/v23.1.20)

+
+## [23.1.4 (Jan 4 2023)](https://github.com/google/flatbuffers/releases/tag/v23.1.4)
+
+* Major release! Just kidding, we are continuing the
+  [versioning scheme](https://github.com/google/flatbuffers/wiki/Versioning) of
+  using a date to signify releases. This results in the first release of the new
+  year to bump the tradition major version field.
+
+* Go minimum version is now 1.19 (#7720) with the addition of Go modules.
+
+* Added CI support for Big Endian regression testing (#7707).
+
+* Fixed `getFullyQualifiedName` in typescript to return name delimited by '.'
+  instead of '_' (#7730).
+
+* Fixed the versioning scheme to not include leading zeros which are not
+  consistently handled by every package manager. Only the last release
+  (12.12.06) should have suffered from this.

+
+## [22.9.29 (Sept 29 2022)](https://github.com/google/flatbuffers/releases/tag/v22.9.29)

+```
+and this will be okay. Old code will not recognize `another_a`.
+However if we add `another_a` anywhere but the end, e.g.
+```
+union Foo { A, another_a: A, B }
+```
+this is not okay. When new code writes `another_a`, old code will
+misinterpret it as `B` (and vice versa). However you can explicitly
+set the union's "discriminant" value like so:
+```
+union Foo { A = 1, another_a: A = 3, B = 2 }
+```
+This is okay.
+
+```
+union Foo { original_a: A = 1, another_a: A = 3, B = 2 }
+```
+Renaming fields will break code and any saved human readable representations,
+such as json files, but the binary buffers will be the same.
