   1Git 2.23 Release Notes
   2======================
   3
   4Updates since v2.22
   5-------------------
   6
   7Backward compatibility note
   8
   9 * The "--base" option of "format-patch" computed the patch-ids for
  10   prerequisite patches in an unstable way, which has been updated to
  11   compute in a way that is compatible with "git patch-id --stable".
  12
  13
  14UI, Workflows & Features
  15
  16 * The "git fast-export/import" pair has been taught to handle commits
  17   with log messages in encoding other than UTF-8 better.
  18
  19 * In recent versions of Git, per-worktree refs are exposed in
  20   refs/worktrees/<wtname>/ hierarchy, which means that worktree names
  21   must be a valid refname component.  The code now sanitizes the names
  22   given to worktrees, to make sure these refs are well-formed.
  23
  24 * "git merge" learned "--quit" option that cleans up the in-progress
  25   merge while leaving the working tree and the index still in a mess.
  26
  27 * "git format-patch" learns a configuration to set the default for
  28   its --notes=<ref> option.
  29
  30 * The code to show args with potential typo that cannot be
  31   interpreted as a commit-ish has been improved.
  32
  33 * "git clone --recurse-submodules" learned to set up the submodules
  34   to ignore commit object names recorded in the superproject gitlink
  35   and instead use the commits that happen to be at the tip of the
  36   remote-tracking branches from the get-go, by passing the new
  37   "--remote-submodules" option.
  38
  39 * The pattern "git diff/grep" use to extract funcname and words
  40   boundary for Matlab has been extend to cover Octave, which is more
  41   or less equivalent.
  42
  43 * "git help git" was hard to discover (well, at least for some
  44   people).
  45
  46 * The pattern "git diff/grep" use to extract funcname and words
  47   boundary for Rust has been added.
  48
  49
  50Performance, Internal Implementation, Development Support etc.
  51
  52 * Update supporting parts of "git rebase" to remove code that should
  53   no longer be used.
  54
  55 * Developer support to emulate unsatisfied prerequisites in tests to
  56   ensure that the remainer of the tests still succeeds when tests
  57   with prerequisites are skipped.
  58
  59 * "git update-server-info" learned not to rewrite the file with the
  60   same contents.
  61
  62 * The way of specifying the path to find dynamic libraries at runtime
  63   has been simplified.  The old default to pass -R/path/to/dir has been
  64   replaced with the new default to pass -Wl,-rpath,/path/to/dir,
  65   which is the more recent GCC uses.  Those who need to build with an
  66   old GCC can still use "CC_LD_DYNPATH=-R"
  67
  68 * Prepare use of reachability index in topological walker that works
  69   on a range (A..B).
  70
  71 * A new tutorial targetting specifically aspiring git-core
  72   developers has been added.

  76Fixes since v2.22
  77-----------------
  78
  79 * A relative pathname given to "git init --template=<path> <repo>"
  80   ought to be relative to the directory "git init" gets invoked in,
  81   but it instead was made relative to the repository, which has been
  82   corrected.
  83   (merge e1df7fe43f nd/init-relative-template-fix later to maint).
  84
  85 * "git worktree add" used to fail when another worktree connected to
  86   the same repository was corrupt, which has been corrected.
  87   (merge 105df73e71 nd/corrupt-worktrees later to maint).
  88
  89 * The ownership rule for the file descriptor to fast-import remote
  90   backend was mixed up, leading to unrelated file descriptor getting
  91   closed, which has been fixed.
  92   (merge 3203566a71 mh/import-transport-fd-fix later to maint).
  93
  94 * A "merge -c" instruction during "git rebase --rebase-merges" should
  95   give the user a chance to edit the log message, even when there is
  96   otherwise no need to create a new merge and replace the existing
  97   one (i.e. fast-forward instead), but did not.  Which has been
  98   corrected.
  99
 100 * Code cleanup and futureproof.
 101   (merge 31f5256c82 ds/object-info-for-prefetch-fix later to maint).
 102
 103 * More parameter validation.
 104   (merge de99eb0c24 es/grep-require-name-when-needed later to maint).
 105
 106 * "git update-server-info" used to leave stale packfiles in its
 107   output, which has been corrected.
 108   (merge e941c48d49 ew/server-info-remove-crufts later to maint).
 109
 110 * The server side support for "git fetch" used to show incorrect
 111   value for the HEAD symbolic ref when the namespace feature is in
 112   use, which has been corrected.
 113   (merge 533e088250 jk/HEAD-symref-in-xfer-namespaces later to maint).
 114
 115 * "git am -i --resolved" segfaulted after trying to see a commit as
 116   if it were a tree, which has been corrected.
 117   (merge 7663e438c5 jk/am-i-resolved-fix later to maint).
 118
 119 * "git bundle verify" needs to see if prerequisite objects exist in
 120   the receiving repository, but the command did not check if we are
 121   in a repository upfront, which has been corrected.
 122   (merge 3bbbe467f2 js/bundle-verify-require-object-store later to maint).
 123
 124 * "git merge --squash" is designed to update the working tree and the
 125   index without creating the commit, and this cannot be countermanded
 126   by adding the "--commit" option; the command now refuses to work
 127   when both options are given.
 128   (merge 1d14d0c994 vv/merge-squash-with-explicit-commit later to maint).
 129
 130 * The data collected by fsmonitor was not properly written back to
 131   the on-disk index file, breaking t7519 tests occasionally, which
 132   has been corrected.
 133   (merge b5a8169752 js/fsmonitor-unflake later to maint).
 134
 135 * Update to Unicode 12.1 width table.
 136   (merge 5817f9caa3 bb/unicode-12.1-reiwa later to maint).
 137
 138 * The command line to invoke a "git cat-file" command from inside
 139   "git p4" was not properly quoted to protect a caret and running a
 140   broken command on Windows, which has been corrected.
 141   (merge c3f2358de3 mm/p4-unshelve-windows-fix later to maint).
 142
 143 * "git request-pull" learned to warn when the ref we ask them to pull
 144   from in the local repository and in the published repository are
 145   different.
 146   (merge 0454220d66 pb/request-pull-verify-remote-ref later to maint).
 147
 148 * When creating a partial clone, the object filtering criteria is
 149   recorded for the origin of the clone, but this incorrectly used a
 150   hardcoded name "origin" to name that remote; it has been corrected
 151   to honor the "--origin <name>" option.
 152   (merge 1c4a9f9114 xl/record-partial-clone-origin later to maint).
 153
 154 * "git fetch" into a lazy clone forgot to fetch base objects that are
 155   necessary to complete delta in a thin packfile, which has been
 156   corrected.
 157   (merge 810e19322d jt/partial-clone-missing-ref-delta-base later to maint).
 158
 159 * The filter_data used in the list-objects-filter (which manages a
 160   lazily sparse clone repository) did not use the dynamic array API
 161   correctly---'nr' is supposed to point at one past the last element
 162   of the array in use.  This has been corrected.
 163   (merge 7140600e2e md/list-objects-filter-memfix later to maint).
 164
 165 * The description about slashes in gitignore patterns (used to
 166   indicate things like "anchored to this level only" and "only
 167   matches directories") has been revamped.
 168   (merge 1a58bad014 an/ignore-doc-update later to maint).
 169
 170 * The URL decoding code has been updated to avoid going past the end
 171   of the string while parsing %-<hex>-<hex> sequence.
 172   (merge d37dc239a4 md/url-parse-harden later to maint).
 173
 174 * The list of for-each like macros used by clang-format has been
 175   updated.
 176   (merge fc7e03aace mo/clang-format-for-each-update later to maint).
 177
 178 * Other code cleanup, docfix, build fix, etc.
 179   (merge f547101b26 es/git-debugger-doc later to maint).
 180   (merge 7877ac3d7b js/bisect-helper-check-get-oid-return-value later to maint).
 181   (merge 0108f47eb3 sw/git-p4-unshelve-branched-files later to maint).
 182   (merge 9df8f734fd cm/send-email-document-req-modules later to maint).
 183   (merge afc3bf6eb1 ab/hash-object-doc later to maint).
