v2.0.0

Git LFS v2.0.0 brings a number of important bug fixes, some new features, and
a lot of internal refactoring. It also completely removes old APIs that were
deprecated in Git LFS v0.6.

Locking

File Locking is a brand new feature that lets teams communicate when they are
working on files that are difficult to merge. Users are not able to edit or push
changes to any files that are locked by other users. While the feature has been
in discussion for a year, we are releasing a basic locking implementation to
solicit feedback from the community.

You can read an overview of how file locking works on the wiki.

Transfer Queue

LFS 2.0 introduces a new Git Scanner, which walks a range of Git commits looking
for LFS objects to transfer. The Git Scanner is now asynchronous, initiating
large uploads or downloads in the Transfer Queue immediately once an LFS object
is found. Previously, the Transfer Queue waited until all of the Git commits
have been scanned before initiating the transfer. The Transfer Queue also
automatically retries failed uploads and downloads more often.

Deprecations

Git LFS v2.0.0 also drops support for the legacy API in v0.5.0. If you're still
using LFS servers on the old API, you'll have to stick to v1.5.6.
