Changelog

Sourced from flatbuffers's changelog.

22.9.24 (Sept 24 2022)

  • 20 Major releases in a row? Nope, we switched to a new versioning scheme 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 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.

When run under an optimized build and Python 3.13.2t, I saw the

It appears that this is due to freeing Python objects during
unordered_map::clear(), which may release the enclosing critical section
(`nb::lock_self()` on the method). Fix this by deferring destruction of
the both the keys and the values to after the map's destruction.
