• 579325 Use git config core.commentChar when committing, creating merge conflict messages and creating and editing squash messages.
• 579325 CommitConfig: add support for core.commentChar
• 546567 [push, lfs] Tell the pre-push hook whether the push is a dry run

Performance Improvements

• 577948 RewriteGenerator: Fully buffering of input is no longer necessary
• 578020 Lazy loading of .lfsconfig

Bug Fixes

• Fix connection leak for smart http connections
• 579445 Remove stray files (probes or lock files) created by background threads
• 579676 HTTP Smart: set correct HTTP status on error
• 579550 De-couple ServiceLoader calls from class loading
• 579550 GpgSigner: prevent class lock inversion on the default signer
• CommitCommand: call GpgSigner.getDefault() only if indeed signing
• DirCacheCheckout: use a LinkedHashMap instead of HashMap. This guarantees that updates are checked out in git order, which is important for LFS if a .lfsconfig file is used
• 579116 Re-try reading a file when there are concurrent writes and the filesystem does not support atomic rename
• 575629 [sideband] Ensure last bit of progress channel is written
• 544769 LsRemoteCommand: apply url.*.insteadOf to ensure remote URI is translated if used without repository
