FlatBuffers Version 23.1.21 (#7796)

* [TS/JS] Entry point per namespace

* Fix handling of outputpath and array_test

* Attempt to fix generate_code

* Fix cwd for ts in generate_code

* Attempt to fixup bazel and some docs

* Add --ts-flat-files to bazel build to get bundle

* Move to DEFAULT_FLATC_TS_ARGS

* Attempt to add esbuild

* Attempt to use npm instead

* Remove futile attempt to add esbuild

* Attempt to as bazel esbuild

* Shuffle

* Upgrade bazel deps

* Revert failed attempts to get bazel working

* Ignore flatc tests for now

* Add esbuild dependency

* `package.json` Include esbuild

* `WORKSPACE` Add fetching esbuild binary

* Update WORKSPACE

* Unfreeze Lockfile

* Update WORKSPACE

* Update BUILD.bazel

* Rework to suggest instead of running external bundler

* Add esbuild generation to test script

* Prelim bundle test

* Run test JavaScriptTest from flatbuffers 1.x

* Deps upgrade

* Clang format fix

* Revert bazel changes

* Fix newline

* Generate with type declarations

* Handle "empty" root namespace

* Adjust tests for typescript_keywords.ts

* Separate test procedure for old node resolution module output

* Fix rel path for root level re-exports

* Bazel support for esbuild-based flatc

Unfortunately, we lose typing information because the new esbuild method
of generating single files does not generate type information.

The method used here is a bit hack-ish because it relies on parsing the
console output of flatc to figure out what to do.

* Try to fix bazel build for when node isn't present on host

* Auto formatting fixes

* Fix missing generated code

+
+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.
+
+## [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.

-      ** Because the genrule used to call flatc does not have any trivial way of

-        --gen-includes (the default) being defined for flatc, the --gen-includes
-        flag will not work as expected. The way around this is to add a dependency
-        to the flatbuffer_cc_library defined alongside the flatc included Fileset.
-        For example you might define:
-
-        flatbuffer_cc_library(
-            name = "my_fbs",
-            srcs = [ "schemas/foo.fbs" ],

-        //third_party/bazz:bazz_fbs_includes. When compiling the library that
-        includes foo_generated.h, and therefore has my_fbs as a dependency, it
-        will fail to find any of the bazz *_generated.h files unless you also
-        add bazz's flatbuffer_cc_library to your own dependency list, e.g.:
-
-        cc_library(

 ### Make all warnings into errors
 
-By default all Flatbuffers `cmake` targets are build with `-Werror` flag.
-With this flag (or `/WX` for MSVC) C++ compiler will treat all warnings as errors.
-Additionally `-Wall -pedantic -Wextra` (or `/W4` form MSVC) flags are set.
-These flags minimize the number of possible defects in code and keep code highly portable.
-Using these flags is considered good practice but sometimes it can break dependent projects 
-if a compiler is upgraded or a toolset is changed.
-Usually, newer compiler versions add new compile-time diagnostics that were unavailable before.
-These new diagnostic warnings could stop the build process if `-Werror` flag is set.
+By default all Flatbuffers `cmake` targets are **not** built with the `-Werror` 
+(or `/WX` for MSVC) flag that treats any warning as an error. This allows more 
+flexibility for users of Flatbuffers to use newer compilers and toolsets that
+may add new warnings that would cause a build failure.
 
-It is possible to cancel `warnings as errors` flag at `cmake` configuration stage using 
-`FLATBUFFERS_CXX_FLAGS` option. Compilation flags declared in `FLATBUFFERS_CXX_FLAGS` will be 
-appended to the project-level `CMAKE_CXX_FLAGS` variable.
-Examples:
+To enable a stricter build that does treat warnings as errors, set the
+`FLATBUFFERS_STRICT_MODE` `cmake` compliation flag to `ON`. 
 
-- GCC and Clang: `cmake . -D FLATBUFFERS_CXX_FLAGS="-Wno-error"`
-- MSVC: `cmake . -D FLATBUFFERS_CXX_FLAGS="/WX-"`
-- MSVC: `cmake . -D FLATBUFFERS_CXX_FLAGS="/Wv <compiler.version>"`
+```
+cmake . -DFLATBUFFERS_STRICT_MODE=ON
+```
 
+Our CI builds run with strict mode on, ensuring the code that is committed to 
+the project is as portable and warning free as possible. Thus developers
+contributing to the project should enable strict mode locally before making a 
+PR.
