  February 10, 2021

  🚀 A new asyncpg release is here.

  👍 Notable additions include Python 3.9 support, support for recently added
  PostgreSQL types like jsonpath, and last but not least, vastly
  👌 improved executemany() performance. Importantly, executemany() is
  also now atomic, which means that either all iterations succeed, or
  none at all, whereas previously partial results would have remained in
  place, unless executemany() was called in a transaction.

  🛠 There is also the usual assortment of improvements and bugfixes, see the
  details below.

  🚀 This is the last release of asyncpg that supports Python 3.5, which has
  reached EOL last September.
