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.
- Added Nim language support with generator and runtime libraries (#7534).
- Rust soundness fixes to avoid the crate from bing labelled unsafe (#7518).
-
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 intendedAlignOf()
for structs (#7520). -
C# has an official Nuget package now (#7496).
-
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 existingVerifier
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).
-
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.
