# Flatbuffers Change Log

All major or breaking changes will be documented in this file, as well as any
new features that should be highlighted. Minor fixes or improvements are not
necessarily listed.

## 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).

## 2.0.7 (Aug 22 2022)

* This is the first version with an explicit change log, so all the previous
  features will not be listed.

* Verifier now checks that buffers are at least the minimum size required to be
  a flatbuffers (12 bytes). This includes nested flatbuffers, which previously
  could be declared valid at size 0.

* Annotated binaries. Given a flatbuffer binary and a schema (or binary schema)
  one can generate an annotated flatbuffer (.afb) to describe each byte in the
  binary with schema metadata and value.

* First binary schema generator (Lua) to generate Lua code via a .bfbs file.
  This is mostly an implementation detail of flatc internals, but will be slowly
  applied to the other language generators.
