-shaped the way you want it to look for your patchset v2.
+This section will focus on how to send a v2 of your patchset. To learn what
+should go into v2, skip ahead to <<reviewing,Responding to Reviews>> for
+information on how to handle comments from reviewers.
+
+We'll reuse our `psuh` topic branch for v2. Before we make any changes, we'll
+mark the tip of our v1 branch for easy reference:
-When you're ready with the next iteration of your patch, the process is fairly
-similar.
+----
+$ git checkout psuh
+$ git branch psuh-v1
+----
-First, generate your v2 patches again:
+Refine your patch series by using `git rebase -i` to adjust commits based upon
+reviewer comments. Once the patch series is ready for submission, generate your
+patches again, but with some new flags:
----
-$ git format-patch -v2 --cover-letter -o psuh/ master..psuh
+$ git format-patch -v2 --cover-letter -o psuh/ --range-diff master..psuh-v1 master..
----
-This will add your v2 patches, all named like `v2-000n-my-commit-subject.patch`,
-to the `psuh/` directory. You may notice that they are sitting alongside the v1
-patches; that's fine, but be careful when you are ready to send them.
+The `--range-diff master..psuh-v1` parameter tells `format-patch` to include a
+range-diff between `psuh-v1` and `psuh` in the cover letter (see
+linkgit:git-range-diff[1]). This helps tell reviewers about the differences
+between your v1 and v2 patches.
+
+The `-v2` parameter tells `format-patch` to output your patches
+as version "2". For instance, you may notice that your v2 patches are
+all named like `v2-000n-my-commit-subject.patch`. `-v2` will also format
+your patches by prefixing them with "[PATCH v2]" instead of "[PATCH]",
+and your range-diff will be prefaced with "Range-diff against v1".
+
+Afer you run this command, `format-patch` will output the patches to the `psuh/`
+directory, alongside the v1 patches. Using a single directory makes it easy to
+refer to the old v1 patches while proofreading the v2 patches, but you will need
+to be careful to send out only the v2 patches. We will use a pattern like
+"psuh/v2-*.patch" (not "psuh/*.patch", which would match v1 and v2 patches).
Edit your cover letter again. Now is a good time to mention what's different
between your last version and now, if it's something significant. You do not

+Git 2.33.1 Release Notes
+========================
+
+This primarily is to backport various fixes accumulated during the
+development towards Git 2.34, the next feature release.
+
+
+Fixes since v2.33
+-----------------
+
+ * The unicode character width table (used for output alignment) has
+ been updated.
+
+ * Input validation of "git pack-objects --stdin-packs" has been
+ corrected.
+
+ * Bugfix for common ancestor negotiation recently introduced in "git
+ push" codepath.
+
+ * "git pull" had various corner cases that were not well thought out
+ around its --rebase backend, e.g. "git pull --ff-only" did not stop
+ but went ahead and rebased when the history on other side is not a
+ descendant of our history. The series tries to fix them up.
+
+ * "git apply" miscounted the bytes and failed to read to the end of
+ binary hunks.
+
+ * "git range-diff" code clean-up.
+
+ * "git commit --fixup" now works with "--edit" again, after it was
+ broken in v2.32.
+
+ * Use upload-artifacts v1 (instead of v2) for 32-bit linux, as the
+ new version has a blocker bug for that architecture.
+
+ * Checking out all the paths from HEAD during the last conflicted
+ step in "git rebase" and continuing would cause the step to be
+ skipped (which is expected), but leaves MERGE_MSG file behind in
+ $GIT_DIR and confuses the next "git commit", which has been
+ corrected.
+
+ * Various bugs in "git rebase -r" have been fixed.
+
+ * mmap() imitation used to call xmalloc() that dies upon malloc()
+ failure, which has been corrected to just return an error to the
+ caller to be handled.
+
+ * "git diff --relative" segfaulted and/or produced incorrect result
+ when there are unmerged paths.
+
+ * The delayed checkout code path in "git checkout" etc. were chatty
+ even when --quiet and/or --no-progress options were given.
+
+ * "git branch -D <branch>" used to refuse to remove a broken branch
+ ref that points at a missing commit, which has been corrected.
+
+ * Build update for Apple clang.
+
+ * The parser for the "--nl" option of "git column" has been
+ corrected.
+
+ * "git upload-pack" which runs on the other side of "git fetch"
+ forgot to take the ref namespaces into account when handling
+ want-ref requests.
+
+ * The sparse-index support can corrupt the index structure by storing
+ a stale and/or uninitialized data, which has been corrected.
+
+ * Buggy tests could damage repositories outside the throw-away test
+ area we created. We now by default export GIT_CEILING_DIRECTORIES
+ to limit the damage from such a stray test.
+
+ * Even when running "git send-email" without its own threaded
+ discussion support, a threading related header in one message is
+ carried over to the subsequent message to result in an unwanted
+ threading, which has been corrected.
+
+ * The output from "git fast-export", when its anonymization feature
+ is in use, showed an annotated tag incorrectly.
+
+ * Recent "diff -m" changes broke "gitk", which has been corrected.
+
+ * "git maintenance" scheduler fix for macOS.
+
+ * A pathname in an advice message has been made cut-and-paste ready.
+
+ * The "git apply -3" code path learned not to bother the lower level
+ merge machinery when the three-way merge can be trivially resolved
+ without the content level merge.
+
+ * The code that optionally creates the *.rev reverse index file has
+ been optimized to avoid needless computation when it is not writing
+ the file out.
+
+ * "git range-diff -I... <range> <range>" segfaulted, which has been
+ corrected.
+
+ * The order in which various files that make up a single (conceptual)
+ packfile has been reevaluated and straightened up. This matters in
+ correctness, as an incomplete set of files must not be shown to a
+ running Git.
+
+ * The "mode" word is useless in a call to open(2) that does not
+ create a new file. Such a call in the files backend of the ref
+ subsystem has been cleaned up.
+
+ * "git update-ref --stdin" failed to flush its output as needed,
+ which potentially led the conversation to a deadlock.
+
+ * When "git am --abort" fails to abort correctly, it still exited
+ with exit status of 0, which has been corrected.
+
+ * Correct nr and alloc members of strvec struct to be of type size_t.
+
+ * "git stash", where the tentative change involves changing a
+ directory to a file (or vice versa), was confused, which has been
+ corrected.
+
+ * "git clone" from a repository whose HEAD is unborn into a bare
+ repository didn't follow the branch name the other side used, which
+ is corrected.
+
+ * "git cvsserver" had a long-standing bug in its authentication code,
+ which has finally been corrected (it is unclear and is a separate
+ question if anybody is seriously using it, though).
+
+ * "git difftool --dir-diff" mishandled symbolic links.
+
+ * Sensitive data in the HTTP trace were supposed to be redacted, but
+ we failed to do so in HTTP/2 requests.
+
+ * "make clean" has been updated to remove leftover .depend/
+ directories, even when it is not told to use them to compute header
+ dependencies.
+
+ * Protocol v0 clients can get stuck parsing a malformed feature line.
+
+Also contains various documentation updates and code clean-ups.

+the current/spawning process, so the child's PID is reported here as
+a hint for post-processing. (But it is only a hint because the child
+process may be a shell script which doesn't have a session-id.)
++
+This event is generated after the child is started in the background
+and given a little time to boot up and start working. If the child
+startups normally and while the parent is still waiting, the "ready"
+field will have the value "ready".
+If the child is too slow to start and the parent times out, the field
+will have the value "timeout".
+If the child starts but the parent is unable to probe it, the field
+will have the value "error".
++
+After the parent process emits this event, it will release all of its
+handles to the child process and treat the child as a background
+daemon. So even if the child does eventually finish booting up,
+the parent will not emit an updated event.
++
+Note that the `t_rel` field contains the observed run time in seconds
+when the parent released the child process into the background.
+The child is assumed to be a long-running daemon process and may
+outlive the parent process. So the parent's child event times should
+not be compared to the child's atexit times.

`"exec"`::
This event is generated before git attempts to `exec()`
another command rather than starting a child process.
