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 #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 #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 #6387. Worktree-specific configuration is now supported, thanks to @vermiculus in #6202. And improved compatibility with git worktree add is now supported, thanks to @herrerog in #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.
