Changes since Git for Windows v2.51.0 (August 19th 2025)

New Features

  * Comes with PCRE2 v10.46.
  * Comes with cURL v8.16.0. This addresses a bug where fetches/pushes
    could fail with failed to read data from server:
    SEC_E_CONTEXT_EXPIRED (0x80090317) under certain circumstances.
    Also included: a back-port of a fix for a bug where connection
    failures were mistakenly reported as time-outs.
  * Comes with Tig v2.6.0.
  * Comes with MinTTY v3.8.1.
  * Comes with OpenSSL v3.5.3.

Bug Fixes

  * The auto-updater now shows Git for Windows icon in the notification
    also on Windows/ARM64.
  * git clone/git fetch now deals more gracefully with directory / file
    conflicts when the files backend is used for ref storage, by
    failing only the ones that are involved in the conflict while
    allowing others. This is a regression in Git v2.51.0 that was
    reported in Git for Windows and independently also to the Git
    mailing list. This was fixed by merging Git's topic branch kn/
    refs-files-case-insensitive.
  * Support for pathspecs in diff --no-index was somewhat buggy, which
    has been fixed.
  * git sparse-checkout subcommand learned a new clean action to prune
    otherwise unused working-tree files that are outside the areas of
    interest. An earlier version of this had been integrated into
    Microsoft Git already. This was fixed by merging Git's topic branch
    ds/sparse-checkout-clean.
  * git rebase -i failed to clean-up the commit log message when the
    command commits the final one in a chain of "fixup" commands, which
    has been corrected. Backported from Git's topic branch pw/
    rebase-i-cleanup-fix.
  * git subtree did not work correctly when splitting squashed
    subtrees, which has been improved. Backported from Git's topic
    branch cs/subtree-squash-split-fix.
  * Some among git add -p and friends ignored color.diff and/or
    color.ui configuration variables, which is an old regression, which
    has been corrected. This was fixed by merging Git's topic branch jk
    /add-i-color.
  * A corner-case bug in git log -L... has been corrected. This was
    fixed by merging Git's topic branch sg/line-log-boundary-fixes.
  * A broken or malicious git fetch can say that it has the same object
    for many many times, and the upload-pack serving it can exhaust
    memory storing them redundantly, which has been corrected. This was
    fixed by merging Git's topic branch ps/upload-pack-oom-protection.
  * Fixes multiple crashes around midx write-out codepaths. This was
    fixed by merging Git's topic branch ds/midx-write-fixes.
  * git repack --path-walk lost objects in some corner cases, which has
    been corrected. This was fixed by merging Git's topic branch ds/
    path-walk-repack-fix.
  * Under a race against another process that is repacking the
    repository, especially a partially cloned one, git fetch may
    mistakenly think some objects we do have are missing, which has
    been corrected. This was fixed by merging Git's topic branch jk/
    fetch-check-graph-objects-fix.
  * Various options to git diff that makes comparison ignore certain
    aspects of the differences (like "space changes are ignored",
    "differences in lines that match these regular expressions are
    ignored") did not work well with --name-only and friends. This was
    fixed by merging Git's topic branch ly/
    diff-name-only-with-diff-from-content.
  * git diff --no-index run inside a subdirectory under control of a
    Git repository operated at the top of the working tree and stripped
    the prefix from the output, and oddballs like "-" (stdin) did not
    work correctly because of it. Correct the set-up by undoing what
    the set-up sequence did to the current working directory and
    prefix. This was fixed by merging Git's topic branch jc/
    diff-no-index-in-subdir.
  * Various bugs about rename handling in "ort" merge strategy have
    been fixed. This was fixed by merging Git's topic branch en/
    ort-rename-fixes.
  * git push had a code path that led to BUG() but it should have
    reported a regular failure, as it is a response to a usual but
    invalid end-user action to attempt pushing an object that does not
    exist. This was fixed by merging Git's topic branch dl/
    push-missing-object-error.
  * git refs migrate to migrate the reflog entries from a refs backend
    to another had a handful of bugs squashed. This was fixed by
    merging Git's topic branch ps/reflog-migrate-fixes.
  * During interactive rebase, using drop on a merge commit lead to an
    error, which was incorrect. This was fixed by merging Git's topic
    branch js/rebase-i-allow-drop-on-a-merge.
