relnotes: write final 6.9 notes

I've folded bugfixes that only exist to fix 6.9-specific things to the best
of my attention span for this task.

/!\ These are release notes for a release candidate version. Any and all points can be reverted before the final release.

/!\ These are release notes for a release candidate version. Any and all points can be reverted before the final release.

== New Features ==

 * exchange: improve computation of relevant markers for large repos
 * Add a Rust fast-path to speed up update (also for `clone`) from null (up to 4x faster) 

 * install: static data moved from setup.py to pyproject.toml
 * upgrade: disable using the parallel workers optimization on macOS
 * doc: generate separate commands/topics/extension pages
 * extdiff: don't run gui programs when in a cli-only environment
 * clonebundles: stop shell quoting `HGCB_BUNDLE_BASENAME` environment variable
 * rev-branch-cache: disable mmapping by default on Windows

== Backwards Compatibility Changes ==

 * This release drops support for Python 3.6 and 3.7.

== Internal API Changes ==

 * manifest: deprecated readdelta and readfast

 * debugwireproto: redo logging to also work for https
 * rust: use `.cargo/config.toml` instead of `.cargo/config`
 * A whole bunch of typing improvements, which in turn found many bugs
 * Test suite improvements
 * Various packaging improvements

= Mercurial 6.9 =

== Backwards Compatibility Changes ==

 * This release drops support for Python 3.6 and 3.7.
 * Starting with this release and hopefully for the forseeable future,
   we are now building wheels for most architectures.
   /!\ Note that for Rust users installing via `pip` or `pipx`, you will need
   to specify `--no-binary` to continue using Rust since we do not yet package
   the Rust compilation in our wheels. We plan on fixing this for 7.0.
 * Python 3.13 changed how it handles docstrings (namely removing uniform
   leading whitespace for every line), which forced us to align the
   representation of our help text with this new behavior across all versions.
   Due to this and a lack of time and expertise from contributors, a lot of
   existing translations could be missing. The effort of i18n in general has
   died down many years ago, but if this matters to you, feel free to send
   your contributions.
