[Full Changelog](https://github.com/nodegit/nodegit/compare/v0.9.0...v0.10.0)

- Clean mutexes are part of GC. No longer leaves processes running after the script ends [PR #880](https://github.com/nodegit/nodegit/pull/880

- Increased the performance of `ConvenientPatch` by an order of magnitude [PR #883](https://github.com/nodegit/nodegit/pull/883

- `ConvenientPatch`

- `ConvenientPatch` does not have a `patch` or a `delta` property associated with it, if you were using the `delta`, please just use prototype methods `oldFIle`, `newFile`, and `Status`, which are stripped directly from the `delta`.

- `ConvenientPatch#hunks` returns a promise with an array of `ConvenientHunks`.

- `ConvenientHunk`

- `ConvenientHunk` does not have an exposed diffHunk associated with it, but does have the same members as diffHunk:

- `size()` : number of lines in the hunk

- `oldStart()` : old starting position

- `oldLines()` : number of lines in old file

- `newStart()` : new starting position

- `newLines()` : number of lines in new file

- `headerLen()` : length of header

- `header()` : returns the header of the hunk

- `lines()` : returns a promise containing `DiffLines`, not `ConvenientLines`.

- `DiffLine`

- `DiffLine` now contains the members `rawContent()` and `content()`.

- `rawContent()` contains the unformatted content of the line. This is no longer a string from the line to the end of the file.

- `content()` contains the utf8 formatted content of the line.

- `Submodule#setIgnore`, `Submodule#setUpdate`, and `Submodule#setUrl` are now all async. `Submodule#status` and `Submodule#location` are now available [PR #867](https://github.com/nodegit/nodegit/pull/867) and [PR #870](https://github.com/nodegit/nodegit/pull/870)

- `Remote#defaultBranch` is now available [PR #872](https://github.com/nodegit/nodegit/pull/872)

- `Repository#mergeBranches` now takes in a `MergeOptions` parameter [PR #873](https://github.com/nodegit/nodegit/pull/873)

- Remove a NodeGit specific hack to make `Index#addAll` faster since that is fixed in libgit2 [PR #875](https://github.com/nodegit/nodegit/pull/875))
