+Thank you for submitting a PR!
+
+Please delete this standard text once you've created your own description.
+
+If you make changes to any of the code generators (`src/idl_gen*`) be sure to
+[build](https://google.github.io/flatbuffers/flatbuffers_guide_building.html) your project, as it will generate code based on the changes. If necessary
+the code generation script can be directly run (`scripts/generate_code.py`),
+requires Python3. This allows us to better see the effect of the PR.
+
+If your PR includes C++ code, please adhere to the
+[Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html),
+and don't forget we try to support older compilers (e.g. VS2010, GCC 4.6.3),
+so only some C++11 support is available.
+
+For any C++ changes, please make sure to run `sh scripts/clang-format-git.sh`
+
+Include other details as appropriate.

+
+## [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.

+# General function to create FlatBuffer build rules for the given list of
+# schemas.
+#
+# flatbuffers_schemas: A list of flatbuffer schema files to process.
+#
+# schema_include_dirs: A list of schema file include directories, which will be
+# passed to flatc via the -I parameter.
+#
+# custom_target_name: The generated files will be added as dependencies for a
+# new custom target with this name. You should add that target as a dependency
+# for your main target to ensure these files are built. You can also retrieve
+# various properties from this target, such as GENERATED_INCLUDES_DIR,
+# BINARY_SCHEMAS_DIR, and COPY_TEXT_SCHEMAS_DIR.
+#
+# additional_dependencies: A list of additional dependencies that you'd like
+# all generated files to depend on. Pass in a blank string if you have none.
+#
+# generated_includes_dir: Where to generate the C++ header files for these
+# schemas. The generated includes directory will automatically be added to
+# CMake's include directories, and will be where generated header files are
+# placed. This parameter is optional; pass in empty string if you don't want to
+# generate include files for these schemas.
+#
+# binary_schemas_dir: If you specify an optional binary schema directory, binary
+# schemas will be generated for these schemas as well, and placed into the given
+# directory.
+#
+# copy_text_schemas_dir: If you want all text schemas (including schemas from
+# all schema include directories) copied into a directory (for example, if you
+# need them within your project to build JSON files), you can specify that
+# folder here. All text schemas will be copied to that folder.
+#
+# IMPORTANT: Make sure you quote all list arguments you pass to this function!
+# Otherwise CMake will only pass in the first element.
+# Example: build_flatbuffers("${fb_files}" "${include_dirs}" target_name ...)

+# 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

+
+
+**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 compilation (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++`.
