   1 Git v2.41 Release Notes
   2 =======================
   3
   4 UI, Workflows & Features
   5
   6  * Allow information carried on the WWW-AUthenticate header to be
   7    passed to the credential helpers.
   8
   9  * A new "fetch.hideRefs" option can be used to exclude specified refs
  10    from "rev-list --objects --stdin --not --all" traversal for
  11    checking object connectivity, most useful when there are many
  12    unrelated histories in a single repository.
  13
  14  * "git push" has been taught to allow deletion of refs with one-level
  15    names to help repairing a repository who acquired such a ref by
  16    mistake.  In general, we don't encourage use of such a ref, and
  17    creation or update to such a ref is rejected as before.
  18
  19  * Allow "git bisect reset" to check out the original branch when the
  20    branch is already checked out in a different worktree linked to the
  21    same repository.
  22
  23  * A few subcommands have been taught to stop users from working on a
  24    branch that is being used in another worktree linked to the same
  25    repository.
  26
  27  * "git format-patch" learned to write a log-message only output file
  28    for empty commits.
  29
  30  * "git format-patch" honors the src/dst prefixes set to nonstandard
  31    values with configuration variables like "diff.noprefix", causing
  32    receiving end of the patch that expects the standard -p1 format to
  33    break.  "format-patch" has been taught to ignore end-user configuration
  34    and always use the standard prefixes.
  35
  36    This is a backward compatibility breaking change.
  37
  38  * Lift the limitation that colored prompts can only be used with
  39    PROMPT_COMMAND mode.
  40
  41
  42 Performance, Internal Implementation, Development Support etc.
  43
  44  * Code clean-up to clarify directory traversal API.
  45
  46  * Code clean-up to clarify the rule that "git-compat-util.h" must be
  47    the first to be included.
  48
  49  * More work towards -Wunused.
  50
  51  * Instead of forcing each command to choose to honor GPG related
  52    configuration variables, make the subsystem lazily initialize
  53    itself.
  54
  55  * Remove workaround for ancient versions of DocBook to make it work
  56    correctly with groff, which has not been necessary since docbook
  57    1.76 from 2010.
  58
  59  * Code clean-up to include and/or uninclude parse-options.h file as
  60    needed.
  61
  62
  63 Fixes since v2.40
  64 -----------------
  65
  66  * "git fsck" learned to check the index files in other worktrees,
  67    just like "git gc" honors them as anchoring points.
  68    (merge 8d3e7eac52 jk/fsck-indices-in-worktrees later to maint).
  69
  70  * Fix a segfaulting loop.  The function and its caller may need
  71    further clean-up.
  72    (merge c5773dc078 ew/commit-reach-clean-up-flags-fix later to maint).
  73
  74  * "git restore" supports options like "--ours" that are only
  75    meaningful during a conflicted merge, but these options are only
  76    meaningful when updating the working tree files.  These options are
  77    marked to be incompatible when both "--staged" and "--worktree" are
  78    in effect.
  79    (merge ee8a88826a ak/restore-both-incompatible-with-conflicts later to maint).
  80
  81  * Simplify UI to control progress meter given by "git bundle" command.
  82    (merge 8b95521edb jk/bundle-progress later to maint).
  83
  84  * "git bundle" learned that "-" is a common way to say that the input
  85    comes from the standard input and/or the output goes to the
  86    standard output.  It used to work only for output and only from the
  87    root level of the working tree.
  88    (merge 0bbe10313e jk/bundle-use-dash-for-stdfiles later to maint).
  89
  90  * Once we start running, we assumed that the list of alternate object
  91    databases would never change.  Hook into the machinery used to
  92    update the list of packfiles during runtime to update this list as
  93    well.
  94    (merge e2d003dbed ds/reprepare-alternates-when-repreparing-packfiles later to maint).
  95
  96  * The code to parse "git rebase -X<opt>" was not prepared to see an
  97    unparsable option string, which has been corrected.
  98    (merge 15a4cc912e ab/fix-strategy-opts-parsing later to maint).
  99
 100  * "git add -p" while the index is unmerged sometimes failed to parse
 101    the diff output it internally produces and died, which has been
 102    corrected.
 103    (merge 28d1122f9c jk/add-p-unmerged-fix later to maint).
 104
 105  * Fix for a "ls-files --format="%(path)" that produced nonsense
 106    output, which was a bug in 2.38.
 107    (merge cfb62dd006 aj/ls-files-format-fix later to maint).
 108
 109  * "git receive-pack" that responds to "git push" requests failed to
 110    clean a stale lockfile when killed in the middle, which has been
 111    corrected.
 112    (merge c55c30669c ps/receive-pack-unlock-before-die later to maint).
 113
 114  * "git rev-parse --quiet foo@{u}", or anything that asks @{u} to be
 115    parsed with GET_OID_QUIETLY option, did not quietly fail, which has
 116    been corrected.
 117    (merge dfbfdc521d fc/oid-quietly-parse-upstream later to maint).
 118
 119  * Transports that do not support protocol v2 did not correctly fall
 120    back to protocol v0 under certain conditions, which has been
 121    corrected.
 122    (merge eaa0fd6584 jk/fix-proto-downgrade-to-v0 later to maint).
 123
 124  * time(2) on glib 2.31+, especially on Linux, goes out of sync with
 125    higher resolution timers used for gettimeofday(2) and by the
 126    filesystem.  Replace all calls to it with a git_time() wrapper and
 127    (merge 370ddcbc89 pe/time-use-gettimeofday later to maint).
 128
 129  * Code clean-up to use designated initializers in parse-options API.
 130    (merge 353e6d4554 sg/parse-options-h-initializers later to maint).
 131
 132  * A recent-ish change to allow unicode character classes to be used
 133    with "grep -P" triggered a JIT bug in older pcre2 libraries.
 134    The problematic change in Git built with these older libraries has
 135    been disabled to work around the bug.
 136    (merge 14b9a04479 mk/workaround-pcre-jit-ucp-bug later to maint).
 137
 138  * Other code cleanup, docfix, build fix, etc.
 139    (merge f7111175df as/doc-markup-fix later to maint).
 140    (merge 90ff7c9898 fc/test-aggregation-clean-up later to maint).
 141    (merge 9b0c7f308a jc/am-doc-refer-to-format-patch later to maint).
 142    (merge b10cbdac4c bb/unicode-width-table-15 later to maint).
 143    (merge 3457b50e8c ab/retire-scripted-add-p later to maint).
 144    (merge d52fcf493b ds/p2000-fix-grep-sparse later to maint).
 145    (merge ec063d2591 ss/hashmap-typofix later to maint).
