7 Backward compatibility notes
9 * "feature.experimental" configuration variable is to let volunteers
10 easily opt into a set of newer features, which use of the v2
11 transport protocol is now a part of.
14 UI, Workflows & Features
16 * The commands in the "diff" family learned to honor "diff.relative"
17 configuration variable.
19 * The check in "git fsck" to ensure that the tree objects are sorted
20 still had corner cases it missed unsorted entries.
23 Performance, Internal Implementation, Development Support etc.
25 * Code optimization for a common case.
26 (merge 8777616e4d an/merge-single-strategy-optim later to maint).
28 * We've adopted a convention that any on-stack structure can be
29 initialized to have zero values in all fields with "= { 0 }",
30 even when the first field happens to be a pointer, but sparse
31 complained that a null pointer should be spelled NULL for a long
32 time. Start using -Wno-universal-initializer option to squelch
33 it (the latest sparse has it on by default).
35 * "git log -L..." now takes advantage of the "which paths are touched
36 by this commit?" info stored in the commit-graph system.
38 * As FreeBSD is not the only platform whose regexp library reports
39 a REG_ILLSEQ error when fed invalid UTF-8, add logic to detect that
40 automatically and skip the affected tests.
42 * "git bugreport" learns to report what shell is in use.
44 * Support for GIT_CURL_VERBOSE has been rewritten in terms of
47 * Preliminary clean-ups around refs API, plus file format
48 specification documentation for the reftable backend.
50 * Workaround breakage in MSVC build, where "curl-config --cflags"
51 gives settings appropriate for GCC build.
57 * The "--prepare-p4-only" option of "git p4" is supposed to stop
58 after replaying one changeset, but kept going (by mistake?)
60 * The error message from "git checkout -b foo -t bar baz" was
63 * Some repositories in the wild have commits that record nonsense
64 committer timezone (e.g. rails.git); "git fast-import" learned an
65 option to pass these nonsense timestamps intact to allow recreating
66 existing repositories as-is.
67 (merge d42a2fb72f en/fast-import-looser-date later to maint).
69 * The command line completion script (in contrib/) tried to complete
70 "git stash -p" as if it were "git stash push -p", but it was too
71 aggressive and also affected "git stash show -p", which has been
73 (merge fffd0cf520 vs/complete-stash-show-p-fix later to maint).
75 * On-the-wire protocol v2 easily falls into a deadlock between the
76 remote-curl helper and the fetch-pack process when the server side
77 prematurely throws an error and disconnects. The communication has
78 been updated to make it more robust.
80 * "git checkout -p" did not handle a newly added path at all.
81 (merge 2c8bd8471a js/checkout-p-new-file later to maint).
83 * The code to parse "git bisect start" command line was lax in
84 validating the arguments.
85 (merge 4d9005ff5d cb/bisect-helper-parser-fix later to maint).
87 * Reduce memory usage during "diff --quiet" in a worktree with too
88 many stat-unmatched paths.
89 (merge d2d7fbe129 jk/diff-memuse-optim-with-stat-unmatch later to maint).
91 * The reflog entries for "git clone" and "git fetch" did not
92 anonymize the URL they operated on.
93 (merge 46da295a77 js/reflog-anonymize-for-clone-and-fetch later to maint).
95 * The behaviour of "sparse-checkout" in the state "git clone
96 --no-checkout" left was changed accidentally in 2.27, which has
99 * Use of negative pathspec, while collecting paths including
100 untracked ones in the working tree, was broken.
102 * Other code cleanup, docfix, build fix, etc.
