+ been corrected.

+ + t: avoid sed-based chain-linting in some expensive cases
 
- Document that "format-patch" skips merges.
+ The "chainlint" feature in the test framework is a handy way to
+ catch common mistakes in writing new tests, but tends to get
+ expensive.  An knob to selectively disable it has been introduced
+ to help running tests that the developer has not modified.

+ end over protocol v2.

+* lh/maintenance-leakfix (2021-05-12) 1 commit
+  (merged to 'next' on 2021-05-13 at 38d02fe309)
+ + maintenance: fix two memory leaks
 
- When the reachability bitmap is in effect, the "do not lose

-  (merged to 'next' on 2021-04-30 at 829167e135)
- + apply: adjust messages to account for --3way changes
-
- When we swapped the order of --3way fallback, we forgot to adjust

-
- "git add" and "git rm" learned not to touch those paths that are
- outside of sparse checkout.
-
-
-* nc/submodule-update-quiet (2021-05-03) 1 commit
-  (merged to 'next' on 2021-05-04 at 09bed89b60)

- Replace GIT_CONFIG_NOSYSTEM mechanism to decline from reading the
- system-wide configuration file with GIT_CONFIG_SYSTEM that lets

+ combination of options has taught to error out.

- The way the command line specified by the trailer.<token>.command
- configuration variable receives the end-user supplied value was
- both error prone and misleading.  An alternative to achieve the
- same goal in a safer and more intuitive way has been added, as
- the trailer.<token>.cmd configuration variable, to replace it.
