As usual, it contains numerous +bug fixes, compatibility improvements, and new features. + +This is expected to be the final release in the libgit2 v1.x lineage. +libgit2 v2.0 is expected to be the next version, with support for +SHA256 moving to "supported" status (out of "experimental" status). +This means that v2.0 will have API and ABI changes to support SHA256. + +## Major changes + +* **Documentation improvements** + We've launched a new website for our API reference docs at + https://libgit2.org/docs/reference/main/. To support this, + we've updated the documentation to ensure that all APIs are + well-documented, and added docurium-style specifiers to indicate + more depth about the API surface. + + We now also publish a JSON blob with the API structure and the + documentation that may be helpful for binding authors. + +* **TLS cipher updates** + libgit2 has updated our TLS cipher selection to match the + "compatibility" cipher suite settings as [documented by + Mozilla](https://wiki.mozilla.org/Security/Server_Side_TLS). + +* **Blame improvements** + The blame API now contains committer information and commit summaries + for blame hunks, and the ability to get information about the line of + text that was modified. In addition, a CLI blame command has been added + so that the blame functionality can be benchmarked by our benchmark + suite. + +* **More CLI commands** + libgit2 has added `blame` and `init` commands, which have allowed for + [further benchmarking](https://benchmarks.libgit2.org/) and several API + improvements and git compatibility updates. + +* **Warning when configuring without SHA1DC** + Users are encouraged to use SHA1DC, which is _git's hash_; users + should not use SHA1 in the general case. Users will now be warned + if they try to configure cmake with a SHA1 backend (`-DUSE_SHA1=...`). + +## Breaking changes + +There are several ABI-breaking changes that integrators, particularly +maintainers of bindings or FFI users, may want to be aware of. + +* **Blame hunk structure updates** (ABI breaking change) + There are numerous additions to the `git_blame_hunk` structure to + accommodate more information about the blame process. + +* **Checkout strategy updates** (ABI breaking change) + The values for `GIT_CHECKOUT_SAFE` and `GIT_CHECKOUT_NONE` have been + updated. `GIT_CHECKOUT_SAFE` is now `0`; this was implicitly the + default value (with the options constructors setting that as the + checkout strategy). It is now the default if the checkout strategy + is set to `0`. This allows for an overall code simplification in the + library. + +* **Configuration entry member removal** (ABI breaking change) + The `git_config_entry` structure no longer contains a `free` member; + this was an oversight as end-users should not try to free that + structure. + +* **Configuration backend function changes** (ABI breaking change) + `git_config_backend`s should now return `git_config_backend_entry` + objects instead of `git_config_entry` objects. This allows backends + to provide a mechanism to nicely free the configuration entries that + they provide. + +* **`update_refs` callback for remotes** (ABI breaking change) + The `update_refs` callback was added to the `git_remote_callbacks` + structure to provide additional information about updated refs; + in particular, the `git_refspec` is included for more information + about the remote ref. The `update_refs` callback will be + preferred over the now deprecated `update_tips` callback. + +## What's Changed + +### New features + +* The `git_signature_default_from_env` API will now produce a pair + of `git_signature`s representing the author, and the committer, + taking the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME` environment + variables into account. Added by @u-quark in + https://github.com/libgit2/libgit2/pull/6706 + +* packbuilder can now be interrupted from a callback. Added @roberth + in https://github.com/libgit2/libgit2/pull/6874 + +* libgit2 now claims to honor the `preciousObject` repository extension. + This extension indicates that the client will never delete objects + (in other words, will not garbage collect). libgit2 has no functionality + to remove objects, so it implicitly obeys this in all cases. Added + by @ethomson in https://github.com/libgit2/libgit2/pull/6886 + +* Push status will be reported even when a push fails. This is useful + to give information from the server about possible updates, even when + the overall status failed. Added by @yerseg in + https://github.com/libgit2/libgit2/pull/6876 + +* You can now generate a thin pack from a mempack instance using + `git_mempack_write_thin_pack`. Added by @roberth in + https://github.com/libgit2/libgit2/pull/6875 + +* The new `LIBGIT2_VERSION_CHECK` macro will indicate whether the version + of libgit2 being compiled against is at least the version specified. + For example: `#if LIBGIT2_VERSION_CHECK(1, 6, 3)` is true for libgit2 + version 1.6.3 or newer. In addition, the new `LIBGIT2_VERSION_NUMBER` + macro will return an integer version representing the libgit2 version + number. For example, for version 1.6.3, `LIBGIT2_VERSION_NUMBER` will + evaluate to `010603`. Added by @HamedMasafi in + https://github.com/libgit2/libgit2/pull/6882 + +* Custom X509 certificates can be added to OpenSSL's certificate store + using the `GIT_OPT_ADD_SSL_X509_CERT` option. Added by @yerseg in + https://github.com/libgit2/libgit2/pull/6877 + +* The libgit2 compatibility CLI now has a `git blame` command. Added by + @ethomson in https://github.com/libgit2/libgit2/pull/6907 + +* Remote callbacks now provide an `update_refs` callback so that users + can now get the `refspec` of the updated reference during push. This + gives more complete information about the remote reference that was + updated. Added by @ethomson in + https://github.com/libgit2/libgit2/pull/6559 + +* An optional FIPS-compliant mode for hashing is now available; you + can set `-DUSE_SHA256=OpenSSL-FIPS` to enable it. Added by @marcind-dot + in https://github.com/libgit2/libgit2/pull/6906 + +* The git-compatible CLI now supports the `git init` command, which has + been useful in identifying API improvements and incompatibilities with + git. Added by @ethomson in https://github.com/libgit2/libgit2/pull/6984 + +* Consumers can now query more information about how libgit2 was + compiled, and query the "backends" that libgit2 uses.

To support +the report unchanged tips option, users can set the `update_fetchhead` +member to include the `GIT_REMOTE_UPDATE_REPORT_UNCHANGED` value. + +The libgit2 projects regrets the API change, but this was required to +support cross-platform compatibility. + +## What's Changed + +### New features + +* Allow more control over the user-agent by @ethomson in + https://github.com/libgit2/libgit2/pull/6788 + +### Bug fixes + +* commit: Fix git_commit_create_from_stage without author and + committer by @florianpircher in + https://github.com/libgit2/libgit2/pull/6781 +* process.c: fix environ for macOS by @barracuda156 in + https://github.com/libgit2/libgit2/pull/6792 +* Bounds check for pack index read by @ConradIrwin in + https://github.com/libgit2/libgit2/pull/6796 +* transport: provide a useful error message during cancellation + by @ethomson in https://github.com/libgit2/libgit2/pull/6802 +* transport: support sha256 oids by @ethomson in + https://github.com/libgit2/libgit2/pull/6803 +* Revparse: Correctly accept ref with '@' at the end by @csware in + https://github.com/libgit2/libgit2/pull/6809 +* remote: drop bitfields in git_remote_fetch_options by @ethomson in + https://github.com/libgit2/libgit2/pull/6806 +* examples: fix memory leak in for-each-ref.c by @qaqland in + https://github.com/libgit2/libgit2/pull/6808 +* xdiff: use proper free function by @ethomson in + https://github.com/libgit2/libgit2/pull/6810 +* rand: avoid uninitialized loadavg warnings by @ethomson in + https://github.com/libgit2/libgit2/pull/6812 +* cli: include alloca on illumos / solaris / sunos by @ethomson in + https://github.com/libgit2/libgit2/pull/6813 +* Update git_array allocator to obey strict aliasing rules + by @ethomson in https://github.com/libgit2/libgit2/pull/6814 +* tree: avoid mixed signedness comparison by @ethomson in + https://github.com/libgit2/libgit2/pull/6815 + +### Build and CI improvements + +* ci: update nightly workflows by @ethomson in + https://github.com/libgit2/libgit2/pull/6773 +* ci: give all nightly builds a unique id by @ethomson in + https://github.com/libgit2/libgit2/pull/6782 +* cmake: remove workaround that isn't compatible with Windows on + ARM by @hackhaslam in https://github.com/libgit2/libgit2/pull/6794 + +### Documentation improvements + +* Docs meta-updates by @ethomson in + https://github.com/libgit2/libgit2/pull/6787 + +### Dependency updates + +* Enable llhttp for HTTP parsing by @sgallagher in + https://github.com/libgit2/libgit2/pull/6713 + +## New Contributors + +* @florianpircher made their first contribution in + https://github.com/libgit2/libgit2/pull/6781 +* @barracuda156 made their first contribution in + https://github.com/libgit2/libgit2/pull/6792 +* @sgallagher made their first contribution in + https://github.com/libgit2/libgit2/pull/6713 +* @ConradIrwin made their first contribution in + https://github.com/libgit2/libgit2/pull/6796 +* @qaqland made their first contribution in + https://github.com/libgit2/libgit2/pull/6808 + +**Full Changelog**: https://github.com/libgit2/libgit2/compare/v1.8.0...v1.8.1 + +v1.8 +---- + +This is release v1.8.0, "Das Fliegende Klassenzimmer". This release +includes optional, experimental support for invoking OpenSSH to fetch +and push, an easier mechanism to perform the default behavior of +`git commit`, and has many improvements for worktrees. This release +also includes many other new features and bugfixes. + +## Major changes + +* **Executable SSH (OpenSSH) support** + libgit2 can now invoke the command-line OpenSSH to fetch from and push + to remotes over SSH. This support takes the place of libssh2 support. + To use it, configure libgit2 with `cmake -DUSE_SSH=exec`, and please + report any problems that you discover. By @ethomson in + https://github.com/libgit2/libgit2/pull/6617 + +* **Simplified commit creation** + The `git_commit_create_from_stage` API was introduced to allow users to + better emulate the behavior of `git commit` without needing to provide + unnecessary information. The current state of the index is committed to + the current branch. By @ethomson in + https://github.com/libgit2/libgit2/pull/6716 + +* **Worktree improvements** + A number of worktree improvements have been made for better + compatibility with core git. First, libgit2 now understands per-worktree + references, thanks to @csware in + https://github.com/libgit2/libgit2/pull/6387. Worktree-specific + configuration is now supported, thanks to @vermiculus in + https://github.com/libgit2/libgit2/pull/6202. And improved compatibility + with `git worktree add` is now supported, thanks to @herrerog in + https://github.com/libgit2/libgit2/pull/5319. + +## Breaking changes + +* **Adding `WORKTREE` configuration level** (ABI breaking change) + To support worktree configurations at the appropriate level (higher + priority than local configuration, but lower priority than app-specific + configuration), the `GIT_CONFIG_LEVEL_WORKTREE` level was introduced at + priority 6. `GIT_CONFIG_LEVEL_APP` now begins at priority 7. + +* **Changes to `git_config_entry`** (ABI breaking change) + The `git_config_entry` structure now contains information about the + `backend_type` and `origin_path`. The unused `payload` value has been + removed. + +* **`git_push_options` includes remote push options** (ABI breaking change) + The `git_push_options` structure now contains a value for remote push + options. + +## Other changes + +### New features + +* config: provide an "origin" for config entries by @ethomson in + https://github.com/libgit2/libgit2/pull/6615 +* cli: add a `git config` command

https://github.com/libgit2/libgit2/compare/v1.7.0...v1.8.0 + +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.
