+
+* 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)
+
+* Reworked entry points for Typescript/Javascript and compatibility for single
+  file build (#7510)
+
+## [23.1.20 (Jan 20 2023)](https://github.com/google/flatbuffers/releases/tag/v23.1.20)
+
+* Removed go.mod files after some versioning issues were being report (#7780).
+
+## [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.
+
+## [22.12.06 (Dec 06 2022)](https://github.com/google/flatbuffers/releases/tag/v22.12.06)
+
+* Bug fixing release, no major changes.
+
+## [22.10.25 (Oct 25 2022)](https://github.com/google/flatbuffers/releases/tag/v22.10.25)
+
+* Added Nim language support with generator and runtime libraries (#7534).
+
+## [22.9.29 (Sept 29 2022)](https://github.com/google/flatbuffers/releases/tag/v22.9.29)
+
+* Rust soundness fixes to avoid the crate from bing labelled unsafe (#7518).
+
+## [22.9.24 (Sept 24 2022)](https://github.com/google/flatbuffers/releases/tag/v22.9.24)
+
+* 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
+  [official 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.

+Contributing    {#contributing}
+============
+
+Want to contribute? Great! First, read this page (including the small print at
+the end).
+
+# Before you contribute
+Before we can use your code, you must sign the
+[Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual?csw=1)
+(CLA), which you can do online. The CLA is necessary mainly because you own the
+copyright to your changes, even after your contribution becomes part of our
+codebase, so we need your permission to use and distribute your code. We also
+need to be sure of various other things—for instance that you'll tell us if you
+know that your code infringes on other people's patents. You don't have to sign
+the CLA until after you've submitted your code for review and a member has
+approved it, but you must do it before we can put your code into our codebase.
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.
+
+# Code reviews
+All submissions, including submissions by project members, require review. We
+use Github pull requests for this purpose.
+
+Some tips for good pull requests:
+* Use our code
+  [style guide](https://google.github.io/styleguide/cppguide.html).
+  When in doubt, try to stay true to the existing code of the project.
+* Write a descriptive commit message. What problem are you solving and what
+  are the consequences? Where and what did you test? Some good tips:
+  [here](http://robots.thoughtbot.com/5-useful-tips-for-a-better-commit-message)
+  and [here](https://www.kernel.org/doc/Documentation/SubmittingPatches).
+* If your PR consists of multiple commits which are successive improvements /
+  fixes to your first commit, consider squashing them into a single commit
+  (`git rebase -i`) such that your PR is a single commit on top of the current
+  HEAD. This make reviewing the code so much easier, and our history more
+  readable.
+
+# The small print
+Contributions made by corporations are covered by a different agreement than
+the one above, the Software Grant and Corporate Contributor License Agreement.

+# Format Guidelines
+
+If you are interesting in contributing to the flatbuffers project, please take a second to read this document. Each language has it's own set of rules, that are defined in their respective formatter/linter documents.
+
+# Notes
+
+- Run the linter on the language you are working on before making a Pull Request.
+- DONT format/lint the generated code.
+
+# Languages
+
+## C++
+
+C++ uses `clang-format` as it's formatter. Run the following script `sh scripts/clang-format-git.sh`, and it should style the C++ code according to [google style guide](https://google.github.io/styleguide/cppguide.html).
+
+## Swift
+
+Swift uses swiftformat as it's formatter. Take a look at [how to install here](https://github.com/nicklockwood/SwiftFormat/blob/master/README.md#how-do-i-install-it). Run the following command `swiftformat --config swift.swiftformat .` in the root directory of the project
+
+## Typescript
+
+Typescript uses eslint as it's linter. Take a look at [how to install here](https://eslint.org/docs/user-guide/getting-started). Run the following command `eslint ts/** --ext .ts` in the root directory of the project

+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+      agreed to in writing, Licensor provides the Work (and each

+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only

+
+**FlatBuffers** is a cross platform serialization library architected for
+maximum memory efficiency. It allows you to directly access serialized data without parsing/unpacking it first, while still having great forwards/backwards compatibility.
+
+## Quick Start
+
+1. Build the compiler for flatbuffers (`flatc`)
+
+    Use `cmake` to create the build files for your platform and then perform the compliation (Linux example).
+
+    ```
+    cmake -G "Unix Makefiles"
+    make -j
+    ```
+
+2. Define your flatbuffer schema (`.fbs`)
+
+    Write the [schema](https://flatbuffers.dev/flatbuffers_guide_writing_schema.html) to define the data you want to serialize. See [monster.fbs](https://github.com/google/flatbuffers/blob/master/samples/monster.fbs) for an example.
+
+3. Generate code for your language(s)
+
+    Use the `flatc` compiler to take your schema and generate language-specific code:
+
+    ```
+    ./flatc --cpp --rust monster.fbs
+    ```
+    
+    Which generates `monster_generated.h` and `monster_generated.rs` files.
+
+4. Serialize data
+
+    Use the generated code, as well as the `FlatBufferBuilder` to construct your serialized buffer. ([`C++` example](https://github.com/google/flatbuffers/blob/master/samples/sample_binary.cpp#L24-L56))
+
+5. Transmit/store/save Buffer
+
+    Use your serialized buffer however you want. Send it to someone, save it for later, etc...
+
+6. Read the data
+
+    Use the generated accessors to read the data from the serialized buffer.
+    
+    It doesn't need to be the same language/schema version, FlatBuffers ensures the data is readable across languages and schema versions. See the [`Rust` example](https://github.com/google/flatbuffers/blob/master/samples/sample_binary.rs#L92-L106) reading the data written by `C++`.

+GRPC implementation and test
+============================
+
+NOTE: files in `src/` are shared with the GRPC project, and maintained there
+(any changes should be submitted to GRPC instead). These files are copied
+from GRPC, and work with both the Protobuf and FlatBuffers code generator.
+
+`tests/` contains a GRPC specific test, you need to have built and installed
+the GRPC libraries for this to compile. This test will build using the
+`FLATBUFFERS_BUILD_GRPCTEST` option to the main FlatBuffers CMake project.
+
+## Building Flatbuffers with gRPC
+
+### Linux
+
+1. Download, build and install gRPC. See [instructions](https://github.com/grpc/grpc/tree/master/src/cpp).
+    * Lets say your gRPC clone is at `/your/path/to/grpc_repo`.
+    * Install gRPC in a custom directory by running `make install prefix=/your/path/to/grpc_repo/install`.
+2. `export GRPC_INSTALL_PATH=/your/path/to/grpc_repo/install`
+3. `export PROTOBUF_DOWNLOAD_PATH=/your/path/to/grpc_repo/third_party/protobuf`
+4. `mkdir build ; cd build`
+5. `cmake -DFLATBUFFERS_BUILD_GRPCTEST=ON -DGRPC_INSTALL_PATH=${GRPC_INSTALL_PATH} -DPROTOBUF_DOWNLOAD_PATH=${PROTOBUF_DOWNLOAD_PATH} ..`
+6. `make`
+
+For Bazel users:
+
+```shell
+$bazel test src/compiler/...
+```
+
+## Running FlatBuffer gRPC tests
+
+### Linux
+
+1. `export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${GRPC_INSTALL_PATH}/lib`
+2. `make test ARGS=-V`
+
+For Bazel users:
+
+```shell
+$bazel test tests/...

+This can be prevented by making sure all the requests coming to/from python are `Bytes array`
+
+```python
+def say_hello(stub, builder):
+    hello_request = bytes(builder.Output())
+    reply = stub.SayHello(hello_request)
+    r = HelloReply.HelloReply.GetRootAs(reply)
+    print(r.Message())
+```
+
+### Go
+
+- Always requires the `content-type` of the payload to be set to `application/grpc+flatbuffers`
+
+example: `.SayHello(ctx, b, grpc.CallContentSubtype("flatbuffers"))`
