[Full Changelog](https://github.com/nodegit/nodegit/compare/v0.25.0-alpha.3...v0.25.0-alpha.4)

- Fixed bug where signing the init commit failed due to being unable to update the `HEAD` ref.

- Changed `NodeGit.Signature.default` to async, because it actually ends up reading the config.

- Fixed bug where templates were not reporting errors for synchronous methods. It's a bit of a wide net, but in general,

it is now possible certain sync methods in NodeGit will begin failin that did not fail before. This is the correct

behavior.

- Switched `NodeGit.Oid.fromString`'s internal implementation from `git_oid_fromstr` to `git_oid_fromstrp`

- Fixed builds for Electron 4

- Added `NodeGit.Reference.updateTerminal`

- [Fix non-existent / dangling refs cause Repository.prototype.createCommitWithSignature to fail #1624](https://github.com/nodegit/nodegit/pull/1624)

- [Handle new gyp information for electron builds #1623](https://github.com/nodegit/nodegit/pull/1623)
