Just kidding, we are continuing the 90 [versioning scheme](https://github.com/google/flatbuffers/wiki/Versioning) of 91 using a date to signify releases. This results in the first release of the new 92 year to bump the tradition major version field. 93 94* Go minimum version is now 1.19 (#7720) with the addition of Go modules. 95 96* Added CI support for Big Endian regression testing (#7707). 97 98* Fixed `getFullyQualifiedName` in typescript to return name delimited by '.' 99 instead of '_' (#7730). 100 101* Fixed the versioning scheme to not include leading zeros which are not 102 consistently handled by every package manager. Only the last release 103 (12.12.06) should have suffered from this. 104 105## [22.12.06 (Dec 06 2022)](https://github.com/google/flatbuffers/releases/tag/v22.12.06) 106 107* Bug fixing release, no major changes. 108 109## [22.10.25 (Oct 25 2022)](https://github.com/google/flatbuffers/releases/tag/v22.10.25) 110 111* Added Nim language support with generator and runtime libraries (#7534). 112 113## [22.9.29 (Sept 29 2022)](https://github.com/google/flatbuffers/releases/tag/v22.9.29) 114 115* Rust soundness fixes to avoid the crate from bing labelled unsafe (#7518). 116 117## [22.9.24 (Sept 24 2022)](https://github.com/google/flatbuffers/releases/tag/v22.9.24) 118 119* 20 Major releases in a row? Nope, we switched to a new 120 [versioning scheme](https://github.com/google/flatbuffers/wiki/Versioning) 121 that is based on date. 122 123* Python supports fixed size arrays now (#7529). 124 125* Behavior change in how C++ object API uses `UnPackTo`. The original intent of 126 this was to reduce allocations by reusing an existing object to pack data 127 into. At some point, this logic started to merge the states of the two objects 128 instead of clearing the state of the packee. This change goes back to the 129 original intention, the packed object is cleared when getting data packed into 130 it (#7527). 131 132* Fixed a bug in C++ alignment that was using `sizeof()` instead of the intended 133 `AlignOf()` for structs (#7520). 134 135* C# has an 136 [official Nuget package](https://www.nuget.org/packages/Google.FlatBuffers) 137 now (#7496). 138 139## 2.0.8 (Aug 29 2022) 140 141* Fix for `--keep-prefix` the was generating the wrong include statements for 142 C++ (#7469). The bug was introduced in 2.0.7. 143 144* Added the `Verifier::Options` option struct to allow specifying runtime 145 configuration settings for the verifier (#7489). This allows to skip verifying 146 nested flatbuffers, a on-by-default change that was introduced in 2.0.7. This 147 deprecates the existing `Verifier` constructor, which may be removed in a 148 future version. 149 150* Refactor of `tests/test.cpp` that lead to ~10% speedup in compilation of the 151 entire project (#7487). 152 153## 2.0.7 (Aug 22 2022) 154 155* This is the first version with an explicit change log, so all the previous 156 features will not be listed. 157 158* Verifier now checks that buffers are at least the minimum size required to be 159 a flatbuffers (12 bytes). This includes nested flatbuffers, which previously 160 could be declared valid at size 0. 161 162* Annotated binaries. Given a flatbuffer binary and a schema (or binary schema) 163 one can generate an annotated flatbuffer (.afb) to describe each byte in the 164 binary with schema metadata and value. 165 166* First binary schema generator (Lua) to generate Lua code via a .bfbs file. 167 This is mostly an implementation detail of flatc internals, but will be slowly 168 applied to the other language generators. 169
