1 Git 2.22 Release Notes
2 ======================
4 Updates since v2.21
5 -------------------
7 UI, Workflows & Features
9 * "git checkout --no-overlay" can be used to trigger a new mode of
10 checking out paths out of the tree-ish, that allows paths that
11 match the pathspec that are in the current index and working tree
12 and are not in the tree-ish.
14 * The %(trailers) formatter in "git log --format=..." now allows to
15 optionally pick trailers selectively by keyword, show only values,
16 etc.
18 * Four new configuration variables {author,committer}.{name,email}
19 have been introduced to override user.{name,email} in more specific
20 cases.
22 * Command-line completion (in contrib/) learned to tab-complete the
23 "git submodule absorbgitdirs" subcommand.
25 * "git branch" learned a new subcommand "--show-current".
27 * Output from "diff --cc" did not show the original paths when the
28 merge involved renames. A new option adds the paths in the
29 original trees to the output.
31 * The command line completion (in contrib/) has been taught to
32 complete more subcommand parameters.
35 Performance, Internal Implementation, Development Support etc.
37 * The diff machinery, one of the oldest parts of the system, which
38 long predates the parse-options API, uses fairly long and complex
39 handcrafted option parser. This is being rewritten to use the
40 parse-options API.
42 * The implementation of pack-redundant has been updated for
43 performance in a repository with many packfiles.
45 * A more structured way to obtain execution trace has been added.
47 * "git prune" has been taught to take advantage of reachability
48 bitmap when able.
51 Fixes since v2.21
52 -----------------
54 * "git prune-packed" did not notice and complain against excess
55 arguments given from the command line, which now it does.
56 (merge 9b0bd87ed2 rj/prune-packed-excess-args later to maint).
58 * Split-index fix.
59 (merge 6e37c8ed3c nd/split-index-null-base-fix later to maint).
61 * "git diff --no-index" may still want to access Git goodies like
62 --ext-diff and --textconv, but so far these have been ignored,
63 which has been corrected.
64 (merge 287ab28bfa jk/diff-no-index-initialize later to maint).
66 * Unify RPC code for smart http in protocol v0/v1 and v2, which fixes
67 a bug in the latter (lack of authentication retry) and generally
68 improves the code base.
69 (merge a97d00799a jt/http-auth-proto-v2-fix later to maint).
71 * The include file compat/bswap.h has been updated so that it is safe
72 to (accidentally) include it more than once.
73 (merge 33aa579a55 jk/guard-bswap-header later to maint).
75 * The set of header files used by "make hdr-check" unconditionally
76 included sha256/gcrypt.h, even when it is not used, causing the
77 make target to fail. We now skip it when GCRYPT_SHA256 is not in
78 use.
79 (merge f23aa18e7f rj/hdr-check-gcrypt-fix later to maint).
81 * The Makefile uses 'find' utility to enumerate all the *.h header
82 files, which is expensive on platforms with slow filesystems; it
83 now optionally uses "ls-files" if working within a repository,
84 which is a trick similar to how all sources are enumerated to run
85 ETAGS on.
86 (merge 92b88eba9f js/find-lib-h-with-ls-files-when-possible later to maint).
88 * Code cleanup, docfix, build fix, etc.
89 (merge 11f470aee7 jc/test-yes-doc later to maint).
90 (merge 90503a240b js/doc-symref-in-proto-v1 later to maint).
91 (merge 5c326d1252 jk/unused-params later to maint).
92 (merge 68cabbfda3 dl/doc-submodule-wo-subcommand later to maint).
93 (merge 9903623761 ab/receive-pack-use-after-free-fix later to maint).
94 (merge 1ede45e44b en/merge-options-doc later to maint).
95 (merge 3e14dd2c8e rd/doc-hook-used-in-sample later to maint).
96 (merge c271dc28fd nd/no-more-check-racy later to maint).
97 (merge e6e15194a8 yb/utf-16le-bom-spellfix later to maint).
98 (merge bb101aaf0c rd/attr.c-comment-typofix later to maint).

101 (merge dbf47215e3 js/rebase-recreate-merge later to maint).
