7 Backward compatibility notes
10 UI, Workflows & Features
12 * A tutorial on object enumeration has been added.
14 * The branch description ("git branch --edit-description") has been
15 used to fill the body of the cover letters by the format-patch
16 command; this has been enhanced so that the subject can also be
19 * "git rebase --preserve-merges" has been marked as deprecated; this
20 release stops advertising it in the "git rebase -h" output.
22 * The code to generate multi-pack index learned to show (or not to
23 show) progress indicators.
25 * "git apply --3way" learned to honor merge.conflictStyle
26 configuration variable, like merges would.
28 * The custom format for "git log --format=<format>" learned the l/L
29 placeholder that is similar to e/E that fills in the e-mail
30 address, but only the local part on the left side of '@'.
32 * Documentation pages for "git shortlog" now list commit limiting
35 * The patterns to detect function boundary for Elixir language has
38 * The completion script (in contrib/) learned that the "--onto"
39 option of "git rebase" can take its argument as the value of the
42 * The userdiff machinery has been taught that "async def" is another
43 way to begin a "function" in Python.
45 * "git range-diff" learned to take the "--notes=<ref>" and the
46 "--no-notes" options to control the commit notes included in the
47 log message that gets compared.
49 * "git rev-parse --show-toplevel" run outside of any working tree did
50 not error out, which has been corrected.
53 Performance, Internal Implementation, Development Support etc.
55 * Debugging support for lazy cloning has been a bit improved.
57 * Move the definition of a set of bitmask constants from 0ctal
58 literal to (1U<<count) notation.
60 * Test updates to prepare for SHA-2 transition continues.
62 * Crufty code and logic accumulated over time around the object
63 parsing and low-level object access used in "git fsck" have been
66 * The implementation of "git log --graph" got refactored and then its
67 output got simplified.
69 * Follow recent push to move API docs from Documentation/ to header
70 files and update config.h
72 * "git bundle" has been taught to use the parse options API. "git
73 bundle verify" learned "--quiet" and "git bundle create" learned
74 options to control the progress output.
76 * Handling of commit objects that use non UTF-8 encoding during
77 "rebase -i" has been improved.
79 * The beginning of rewriting "git add -i" in C.
81 * A label used in the todo list that are generated by "git rebase
82 --rebase-merges" is used as a part of a refname; the logic to come
83 up with the label has been tightened to avoid names that cannot be
86 * The logic to avoid duplicate label names generated by "git rebase
87 --rebase-merges" forgot that the machinery itself uses "onto" as a
88 label name, which must be avoided by auto-generated labels, which
91 * We have had compatibility fallback macro definitions for "PRIuMAX",
92 "PRIu32", etc. but did not for "PRIdMAX", while the code used the
93 last one apparently without any hiccup reported recently. The
94 fallback macro definitions for these <inttypes.h> macros that must
95 appear in C99 systems have been removed.
97 * Recently we have declared that GIT_TEST_* variables take the
98 usual boolean values (it used to be that some used "non-empty
99 means true" and taking GIT_TEST_VAR=YesPlease as true); make
100 sure we notice and fail when non-bool strings are given to
103 * Users of oneway_merge() (like "reset --hard") learned to take
104 advantage of fsmonitor to avoid unnecessary lstat(2) calls.
106 * Performance tweak on "git push" into a repository with many refs
107 that point at objects we have never heard of.
109 * PerfTest fix to avoid stale result mixed up with the latest round
116 * "rebase -i" ceased to run post-commit hook by mistake in an earlier
117 update, which has been corrected.
119 * "git notes copy $original" ought to copy the notes attached to the
120 original object to HEAD, but a mistaken tightening to command line
121 parameter validation made earlier disabled that feature by mistake.
123 * When all files from some subdirectory were renamed to the root
124 directory, the directory rename heuristics would fail to detect that
125 as a rename/merge of the subdirectory to the root directory, which has
128 * Code clean-up and a bugfix in the logic used to tell worktree local
129 and repository global refs apart.
130 (merge f45f88b2e4 sg/dir-trie-fixes later to maint).
132 * "git stash save" in a working tree that is sparsely checked out
133 mistakenly removed paths that are outside the area of interest.
134 (merge 4a58c3d7f7 js/update-index-ignore-removal-for-skip-worktree later to maint).
136 * "git rev-parse --git-path HEAD.lock" did not give the right path
137 when run in a secondary worktree.
138 (merge 76a53d640f js/git-path-head-dot-lock-fix later to maint).
140 * "git merge --no-commit" needs "--no-ff" if you do not want to move
141 HEAD, which has been corrected in the manual page for "git bisect".
142 (merge 8dd327b246 ma/bisect-doc-sample-update later to maint).
144 * "git worktree add" internally calls "reset --hard" that should not
145 descend into submodules, even when submodule.recurse configuration
146 is set, but it was affected. This has been corrected.
147 (merge 4782cf2ab6 pb/no-recursive-reset-hard-in-worktree-add later to maint).
149 * Messages from die() etc. can be mixed up from multiple processes
150 without even line buffering on Windows, which has been worked
152 (merge 116d1fa6c6 js/vreportf-wo-buffering later to maint).
154 * HTTP transport had possible allocator/deallocator mismatch, which
157 * The watchman integration for fsmonitor was racy, which has been
158 corrected to be more conservative.
159 (merge dd0b61f577 kw/fsmonitor-watchman-fix later to maint).
161 * Fetching from multiple remotes into the same repository in parallel
162 had a bad interaction with the recent change to (optionally) update
163 the commit-graph after a fetch job finishes, as these parallel
164 fetches compete with each other. Which has been corrected.
166 * Recent update to "git stash pop" made the command empty the index
167 when run with the "--quiet" option, which has been corrected.
169 * "git fetch" codepath had a big "do not lazily fetch missing objects
170 when I ask if something exists" switch. This has been corrected by
171 marking the "does this thing exist?" calls with "if not please do not
172 lazily fetch it" flag.
174 * Test update to avoid wasted cycles.
175 (merge e0316695ec sg/skip-skipped-prereq later to maint).
177 * Error handling after "git push" finishes sending the packdata and
178 waits for the response to the remote side has been improved.
179 (merge ad7a403268 jk/send-pack-remote-failure later to maint).
181 * Some codepaths in "gitweb" that forgot to escape URLs generated
182 based on end-user input have been corrected.
183 (merge a376e37b2c jk/gitweb-anti-xss later to maint).
185 * CI jobs for macOS has been made less chatty when updating perforce
186 package used during testing.
187 (merge 0dbc4a0edf jc/azure-ci-osx-fix-fix later to maint).
189 * "git unpack-objects" used to show progress based only on the number
190 of received and unpacked objects, which stalled when it has to
191 handle an unusually large object. It now shows the throughput as
193 (merge bae60ba7e9 sg/unpack-progress-throughput later to maint).
195 * The sequencer machinery compared the HEAD and the state it is
196 attempting to commit to decide if the result would be a no-op
197 commit, even when amending a commit, which was incorrect, and
200 * The code to parse GPG output used to assume incorrectly that the
201 finterprint for the primary key would always be present for a valid
202 signature, which has been corrected.
203 (merge 67a6ea6300 hi/gpg-optional-pkfp-fix later to maint).
205 * "git submodule status" and "git submodule status --cached" show
206 different things, but the documentation did not cover them
207 correctly, which has been corrected.
208 (merge 8d483c8408 mg/doc-submodule-status-cached later to maint).
210 * "git reset --patch $object" without any pathspec should allow a
211 tree object to be given, but incorrectly required a committish,
212 which has been corrected.
214 * "git submodule status" that is run from a subdirectory of the
215 superproject did not work well, which has been corrected.
216 (merge 1f3aea22c7 mg/submodule-status-from-a-subdirectory later to maint).
218 * The revision walking machinery uses resources like per-object flag
219 bits that need to be reset before a new iteration of walking
220 begins, but the resources related to topological walk were not
221 cleared correctly, which has been corrected.
222 (merge 0aa0c2b2ec mh/clear-topo-walk-upon-reset later to maint).
225 (merge 176441bfb5 sg/osx-force-gcc-9 later to maint).
227 * While running "revert" or "cherry-pick --edit" for multiple
228 commits, a recent regression incorrectly detected "nothing to
229 commit, working tree clean", instead of replaying the commits,
230 which has been corrected.
231 (merge befd4f6a81 sg/assume-no-todo-update-in-cherry-pick later to maint).
233 * Other code cleanup, docfix, build fix, etc.
234 (merge 80736d7c5e jc/am-show-current-patch-docfix later to maint).
