v1.7: update changelog

parent bdd03157
v1.7
----
This is release v1.7.0, "Kleine Raupe Nimmersatt". This release adds
shallow clone support, completes the experimental SHA256 support,
adds Schannel support for Windows, and includes many other new
features and bugfixes.
## Major changes
* **Shallow clone support**
libgit2 now supports shallow clone and shallow repositories, thanks
to a significant investment from many community members -- hundreds
of commits by many contributors.
* Shallow (#6396) with some fixes from review by @ethomson in
https://github.com/libgit2/libgit2/pull/6557
* Shallow Clone Support by @lya001 in
https://github.com/libgit2/libgit2/pull/6396
* Shallow support v2 by @pks-t in
https://github.com/libgit2/libgit2/pull/5254
* **SHA256 support**
libgit2 should now support SHA256 repositories using the
`extensions.objectFormat` configuration option when the library is
built with `EXPERIMENTAL_SHA256=ON`. Users are encouraged to begin
testing their applications with this option and provide bug reports
and feedback. This _is_ a breaking API change; SHA256 support will
be enabled by default in libgit2 v2.0.
* sha256: less hardcoded SHA1 types and lengths by @ethomson in
https://github.com/libgit2/libgit2/pull/6549
* Support SHA256 in git_repository_wrap_odb by @ethomson in
https://github.com/libgit2/libgit2/pull/6556
* **Schannel and SSPI for Windows**
libgit2 now supports the Windows Schannel and SSPI APIs for HTTPS
support on Windows, when configured with `USE_HTTPS=Schannel`.
Setting this option will not use the existing WinHTTP support, but
will use libgit2's standard HTTP client stack with Windows TLS
primitives. Windows users are encouraged to begin testing their
applications with this option and provide bug reports and feedback.
This will be enabled by default in a future version of libgit2.
* Introduce Schannel and SSPI for Windows by @ethomson in
https://github.com/libgit2/libgit2/pull/6533
## Breaking changes
* **Simplify custom pluggable allocator** (System API / ABI breaking change)
The `git_allocator` structure (configurable by the
`GIT_OPT_SET_ALLOCATOR` option) now only contains `gmalloc`,
`grealloc` and `gfree` members. This simplifies both the work needed
by an implementer _and_ allows more flexibility and correctness in
libgit2 itself, especially during out-of-memory situations and
errors during bootstrapping.
* tests: add allocator with limited number of bytes by @ethomson in
https://github.com/libgit2/libgit2/pull/6563
