The parent commit, which merged the feature/redrawhook bug and thereby
closed PR #749, also fixed the following issue:
Fixes#40.
Fixes#90, closes#470. (The latter is a PR for the former.)
Fixes#150, closes#151, closes#160. (The latter two are PR's for the first one.) The related issue #183 appears to have been fixed in master. For #150, a different fix for older versions of zsh was considered but has not been implemented.
Issue #154 was fixed in xsel(1) in 2017. The parent commit probably fixed that issue for pre-2017 xsel(1).
Is #245, #356, and #749. Fixes#245 (redrawhook umbrella issue).

* feature/redrawhook:
docs: Track making the new codepath conditional upon the 'memo=' feature.
On the feature/redrawhook branch, changelog: Add entries for issues fixed by this branch.
On the feature/redrawhook branch, change the detection of the 'memo=' feature to avoid a catch-22.

On the feature/redrawhook branch, move the changelog entry to the current release's section.
driver: Fix a bug that prevented subsequent, third-party zle-line-pre-redraw hooks from running.
driver: Do not pass widget arguments to _zsh_highlight
driver: Clarify comment. No functional change.

wrappers: Reimplement using Mikachu's zle-line-pre-redraw hook (workers/36650).
This reverts commit 8a1bd7c8b6.
The detection only works correctly from a widget function, so the change
was wrong: it caused zsh_highlight__memo_feature to be set to false
every time.

driver: Follow-up to grandparent: Have all test suite entry points declare the mock $region_highlight.

...
The error message uses «$1», but it is always unset at that point.
Furthermore, the NO_UNSET (-u) option is in effect. Therefore, when the
error message was to be printed, zsh's NO_UNSET error message was
printed instead:
.
(anon):20: 1: parameter not set
That error message was printed to stderr, and was caught by the caller
within the test harness:
.
Bail out! On './highlighters/main/test-data/path_prefix3.zsh': output on stderr
Thus, the bug being fixed would not caused false positive or false
negative test results, but only wrong error messages.
Follow-up to 0.7.1-71-ge6eea1f, "test harness: Don't leak options from
test files to the test harness".

— it actually makes things measurably slower (!), even on input that has
a large number of pasted double-quoted strings: on «BUFFER=": ${(r.8*1500..foo"bar".):-}"»
the slowdown is (1123.24ms / 1091.06ms = 1.0295). Therefore, I won't be
committing that change.

The great-grandparent commit, "a3ae74 'main': Fix the last commit's bug
concerning parameter elision not happening in redirects in command
position.", is not added because it's not a change with respect
to 0.7.1.
In those versions of zsh, «[[ -o nosuchoption ]]» is regarded as
a syntax error. In newer zsh versions, it merely returns non-zero
(specifically, it returns 3, unlike «[[ -o unsetoption ]]» which
returns 1).
Fixes#732.
Fixes#733.
