+### Documentation
+
+- Replaced all remaining references to the
+ [`master`](https://github.com/psf/black/tree/main) branch with the
+ [`main`](https://github.com/psf/black/tree/main) branch. Some additional changes in

+
+- Fix crash when atypical whitespace is cleaned out of dostrings (#2120)
+
+- 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

+
+- PR #2053: Black no longer relies on typed-ast for Python 3.8 and higher

+ Releases (#1743)
+
+## 20.8b1

+ older than 7.0
