-### Changes or improvements
-
-* Branch and tag name validation functions have been introduced:
-  `git_branch_name_is_valid` will check if a branch name is valid,
-  and `git_tag_name_is_valid` will check if a tag name is valid.
-
-* Some remote and reference validity checking functions have been
-  introduced with error reporting semantics.  `git_remote_name_is_valid`
-  replaces `git_remote_is_valid_name`.  `git_reference_name_is_valid`
-  replaces `git_reference_is_valid_name`.  Tthe former functions are
-  deprecated.
-
-### Breaking CMake configuration changes
-
-The `MVSC_CRTDBG` configuration option is now `WIN32_LEAKCHECK`.
+This is release v1.2.0, "Absacker".  This release includes many new features: in particular, support for commit graphs, multi-pack indexes, and `core.longpaths` support.
+
+This is meant to be the final minor release in the v1 lineage.  v2.0 will be the next major release and will remove deprecated APIs and may include breaking changes.
