1. asyncpg v0.22.0 …

   A new asyncpg release is here, just in time for Christmas.  Notableadditions include Python 3.9 support, support for recently addedPostgreSQL types like `jsonpath`, and last but not least, vastlyimproved `executemany()` performance.  Importantly, `executemany()` isalso now _atomic_, which means that either all iterations succeed, ornone at all, whereas previously partial results would have remained inplace, unless `executemany()` was called in a transaction.There is also the usual assortment of improvements and bugfixes, see thedetails below.This is the last release of asyncpg that supports Python 3.5, which hasreached EOL in September.Improvements------------* Vastly speedup executemany by batching protocol messages (#295)  (by@fantix in690048d for#295)* Allow using custom `Record` class  (by@elprans indb4f1a6 for#577)* Add Python 3.9 support (#610)  (by@elprans inc05d726 for#610)* Prefer SSL connections by default (#660)  (by@elprans in16183aa for#660)* Add codecs for a bunch of new builtin types (#665)  (by@elprans inb53f038 for#665)* Expose Pool as `asyncpg.Pool` (#669)  (by@rugleb in0e0eb8d for#669)Fixes-----* Add a workaround for bpo-37658  (by@elprans in2bac166 for #21894)* Fix wrong default transaction isolation level (#622)  (by@fantix in4a627d5 for#622)* Fix `set_type_codec()` to accept standard SQL type names (#619)  (by@elprans in68b40cb for#619)* Ignore custom data codec for internal introspection (#618)  (by@fantix ine064f59 for#618)* Fix null/NULL quoting in array text encoder (#627)  (by@fantix in92aa806 for#627)* Fix link in connect docstring (#653)  (by@samuelcolvin in8b313bd for#653)* Make asyncpg work with pyinstaller (#651)  (by@Atem18 in5ddabb1 for#651)* Fix possible `AttributeError` exception in `ConnectionSettings` (#632)  (by@petriborg in0d23182 for#632)* Prohibit custom codecs on domains  (by@elprans in50f964f for#457)* Raise proper error on anonymous composite input (tuple arguments) (#664)  (by@elprans in7252dbe for#664)* Fix incorrect application of custom codecs in some cases (#662)  (by@elprans in50f65fb for#662)
