 * Improve the performance of the revwalk and bring us closer to git's code.
 
+* The reference db has improved support for concurrency and returns `GIT_ELOCKED`
+  when an operation could not be performed due to locking.
+
+* Nanosecond resolution is now activated by default, following git's change to
+  do this.
+
+* We now restrict the set of ciphers we let OpenSSL use by default.
+
+* Users can now register their own merge drivers for use with `.gitattributes`.
+  The library also gained built-in support for the union merge driver.
+
+* The default for creating references is now to validate that the object does
+  exist.
+
+* Add `git_proxy_options` which is used by the different networking
+  implementations to let the caller specify the proxy settings instead of
+  relying on the environment variables.

 ### API additions
 
 * You can now get the user-agent used by libgit2 using the
   `GIT_OPT_GET_USER_AGENT` option with `git_libgit2_opts()`.
   It is the counterpart to `GIT_OPT_SET_USER_AGENT`.
 
+* The `GIT_OPT_SET_SSL_CIPHERS` option for `git_libgit2_opts()` lets you specify
+  a custom list of ciphers to use for OpenSSL.

 * `git_commit_create_buffer()` creates a commit and writes it into a
-  user-provided buffer instead of writing it into the object db.
+  user-provided buffer instead of writing it into the object db. Combine it with

+
+* The new `git_blob_dup()`, `git_commit_dup()`, `git_tag_dup()` and
+  `git_tree_dup()` functions provide type-specific wrappers for
+  `git_object_dup()` to reduce noise and increase type safety for callers.
+
+* `git_reference_dup()` lets you duplicate a reference to aid in ownership

+
+* `git_signature_from_buffer()` lets you create a signature from a string in the

+
+* `git_tree_create_updated()` lets you create a tree based on another one

+  efficient than the `git_index` route.
+
+* `git_apply_patch()` applies hunks from a `git_patch` to a buffer.
+
+* `git_diff_to_buf()` lets you print an entire diff directory to a buffer,
+  similar to how `git_patch_to_buf()` works.
+
+* `git_proxy_init_options()` is added to initialize a `git_proxy_options`
+  structure at run-time.
+
+* `git_merge_driver_register()`, `git_merge_driver_unregister()` let you
+  register and unregister a custom merge driver to be used when `.gitattributes`
