+ * When the "clean" filter can reduce the size of a huge file in the
+ working tree down to a small "token" (a la Git LFS), there is no
+ point in allocating a huge scratch area upfront, but the buffer is
+ sized based on the original file size. The convert mechanism now
+ allocates very minimum and reallocates as it receives the output
+ from the clean filter process.
+ (merge 02156ab031 jh/resize-convert-scratch-buffer later to maint).
+
+ * "git rebase" uses the refs/rewritten/ hierarchy to store its
+ intermediate states, which inherently makes the hierarchy per
+ worktree, but it didn't quite work well.
+ (merge b9317d55a3 nd/rewritten-ref-is-per-worktree later to maint).
+
+ * "git log -L<from>,<to>:<path>" with "-s" did not suppress the patch
+ output as it should. This has been corrected.
+ (merge 05314efaea jk/line-log-with-patch later to maint).
+
+ * "git worktree add" used to do a "find an available name with stat
+ and then mkdir", which is race-prone. This has been fixed by using
+ mkdir and reacting to EEXIST in a loop.
+ (merge 7af01f2367 ms/worktree-add-atomic-mkdir later to maint).
+
+ * Build update for SHA-1 with collision detection.
+ (merge 07a20f569b jk/sha1dc later to maint).
+
+ * Build procedure has been fixed around use of asciidoctor instead of
+ asciidoc.
+ (merge 185f9a0ea0 ma/asciidoctor-fixes later to maint).
+
+ * remote-http transport did not anonymize URLs reported in its error
+ messages at places.
+ (merge c1284b21f2 js/anonymize-remote-curl-diag later to maint).
+
+ * Error messages given from the http transport have been updated so
+ that they can be localized.
+ (merge ed8b4132c8 js/remote-curl-i18n later to maint).
+
+ * "git init" forgot to read platform-specific repository
+ configuration, which made Windows port to ignore settings of
+ core.hidedotfiles, for example.
+
+ * A corner-case object name ambiguity while the sequencer machinery
+ is working (e.g. "rebase -i -x") has been fixed.
+
+ * "git format-patch" used overwrite an existing patch/cover-letter
+ file. A new "--no-clobber" option stops it.
