Force compilation failure on exotic platforms + where variadic macros are not available to find out who screams in + such a way that we can easily revert if it turns out that the world + is not yet ready. + + * Code clean-up to ensure our use of hashtables using object names as + keys use the "struct object_id" objects, not the raw hash values. + + * Lose the debugging aid that may have been useful in the past, but + no longer is, in the "grep" codepaths. + + * Some pretty-format specifiers do not need the data in commit object + (e.g. "%H"), but we were over-eager to load and parse it, which has + been made even lazier. + + * Get rid of "GETTEXT_POISON" support altogether, which may or may + not be controversial. + + * Introduce an on-disk file to record revindex for packdata, which + traditionally was always created on the fly and only in-core. + + * The commit-graph learned to use corrected commit dates instead of + the generation number to help topological revision traversal. + + * Piecemeal of rewrite of "git bisect" in C continues. + + * When a pager spawned by us exited, the trace log did not record its + exit status correctly, which has been corrected. + + * Removal of GIT_TEST_GETTEXT_POISON continues. + + * The code to implement "git merge-base --independent" was poorly + done and was kept from the very beginning of the feature. + + * Preliminary changes to fsmonitor integration. + + * Performance improvements for rename detection. + + * The common code to deal with "chunked file format" that is shared + by the multi-pack-index and commit-graph files have been factored + out, to help codepaths for both filetypes to become more robust. + + * The approach to "fsck" the incoming objects in "index-pack" is + attractive for performance reasons (we have them already in core, + inflated and ready to be inspected), but fundamentally cannot be + applied fully when we receive more than one pack stream, as a tree + object in one pack may refer to a blob object in another pack as + ".gitmodules", when we want to inspect blobs that are used as + ".gitmodules" file, for example. Teach "index-pack" to emit + objects that must be inspected later and check them in the calling + "fetch-pack" process. + + * The logic to handle "trailer" related placeholders in the + "--format=" mechanisms in the "log" family and "for-each-ref" + family is getting unified. + + * Raise the buffer size used when writing the index file out from + (obviously too small) 8kB to (clearly sufficiently large) 128kB. + + * It is reported that open() on some platforms (e.g. macOS Big Sur) + can return EINTR even though our timers are set up with SA_RESTART. + A workaround has been implemented and enabled for macOS to rerun + open() transparently from the caller when this happens. + + +Fixes since v2.30 +----------------- + + * Diagnose command line error of "git rebase" early. + + * Clean up option descriptions in "git cmd --help". + + * "git stash" did not work well in a sparsely checked out working + tree. + + * Some tests expect that "ls -l" output has either '-' or 'x' for + group executable bit, but setgid bit can be inherited from parent + directory and make these fields 'S' or 's' instead, causing test + failures. + + * "git for-each-repo --config=<var> <cmd>" should not run <cmd> for + any repository when the configuration variable <var> is not defined + even once. + + * Fix 2.29 regression where "git mergetool --tool-help" fails to list + all the available tools. + + * Fix for procedure to building CI test environment for mac. + + * The implementation of "git branch --sort" wrt the detached HEAD + display has always been hacky, which has been cleaned up. + + * Newline characters in the host and path part of git:// URL are + now forbidden. + + * "git diff" showed a submodule working tree with untracked cruft as + "Submodule commit <objectname>-dirty", but a natural expectation is + that the "-dirty" indicator would align with "git describe --dirty", + which does not consider having untracked files in the working tree + as source of dirtiness. The inconsistency has been fixed. + + * When more than one commit with the same patch ID appears on one + side, "git log --cherry-pick A...B" did not exclude them all when a + commit with the same patch ID appears on the other side. Now it + does. + + * Documentation for "git fsck" lost stale bits that has become + incorrect. + + * Doc fix for packfile URI feature. + + * When "git rebase -i" processes "fixup" insn, there is no reason to + clean up the commit log message, but we did the usual stripspace + processing.

"git branch -M" had the same problem. + (merge 27dc071b9a jk/complete-branch-force-delete later to maint). + + * When commands are started from a subdirectory, they may have to + compare the path to the subdirectory (called prefix and found out + from $(pwd)) with the tracked paths.
