+- Reflect the `--skip-magic-trailing-comma` and `--experimental-string-processing` flags
+ in the name of the cache file. Without this fix, changes in these flags would not take

+ return statements. (#2143)

+#### _Black_
+
+- Fixed a rare but annoying formatting instability created by the combination of
+ optional trailing commas inserted by `Black` and optional parentheses looking at
+ pre-existing "magic" trailing commas. This fixes issue #1629 and all of its many many
+ duplicates. (#2126)
+
