This version is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of nodegit.
Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Do you have any ideas how I could improve these pull requests? Did I report anything you think isn’t right?
Are you unsure about how things are supposed to work?

There is a collection of frequently asked questions and while I’m just a bot, there is a group of people who are happy to teach me new things. Let them know.

Good luck with your project ✨

You rock!

GitHub Release

• Update to libgit2 @ 37dba1a PR #1041

This updates NodeGit to use the latest HEAD version of libgit2. The plan for staying on the official tagged releases of libgit2 is that they will get a maintenance branch and not-breaking API fixes will be backported to them. The first branch of this sort is maint/0.14. Going forward new releases of NodeGit will follow closely to the master branch of libgit2.

Summary of changes that were brought in:

libgit2/libgit2@37dba1a

Changes or improvements

• NodeGit.FetchOptions, and NodeGit.PushOptions now have a proxyOpts field that accepts a NodeGit.ProxyOptions object that allows NodeGit to use a proxy for all remote communication

• NodeGit.MergeOptions has a defaultDriver field that lets the caller change the driver used to when both sides of a merge have changed

API additions

• Commit.createWithSignature allows the caller to create a signed commit. There are no tests for this currently so it's labelled experimental.

• Blob, Commit, Tag, and Tree all have a new prototype dup method on them to make a low-level copy of the libgit2 object if needed.

• Odb#expandIds is exposed which takes in a list of short ids and expands them in-place to the full id of the object in the database
