v0.22.0
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.
Improvements
Vastly speedup executemany by batching protocol messages
Allow using custom Record class
Add Python 3.9 support
Prefer SSL connections by default
Add codecs for a bunch of new builtin types
Expose Pool as asyncpg.Pool
Avoid unnecessary overhead during connection reset

* Properly cleanup connections closed by remote
asyncpg v0.18.1:
Fix DSN parsing regression
asyncpg v0.18.0:
Improvements
Implement Record.get()
Internal asyncpg errors are now consistently raised as InternalClientError
Allow mappings as composite type input
Add BitString.to_int() and BitString.from_int()
Allow 'sslmode' in DSNs
Add support for specifying multiple host addresses when connecting
Low-level protocol implementation has been tweaked and
optimized for slightly better performance in certain scenarios

asyncpg v0.17.0:
Improvements
Official support for Python 3.7.
Bug Fixes
Fix garbage collection of connections and emit a ResourceWarning
if an unclosed connection is garbage collected.
Raise a clear error if there's a race in pool intialization.
Channel names in Connection.add_listener() and
Connection.remove_listener() are now quoted properly.
Fixed endianness detection on *BSD systems.
Fixed handling of large type OIDs.
asyncpg v0.16.0:
Behavior Changes
----------------
Pool.close() now waits until all acquired connections are released.
Hence, the below code will now hang indefinitely:
conn = await pool.acquire()
await pool.close()
Asyncpg will log a warning if pool.close() takes over 60 seconds to
complete. It is advisable to use asyncio.wait_for() to set a timeout.
Improvements
------------
Add support for reading passwords from .pgpass
Add Connection.is_in_transaction()
Added codec for built-in type tid
Allow setting custom codecs on domains and enumerated types
Allow passing datetime.date instances as timestamp input
Implement support for pool connection rotation
Bug Fixes
---------
Prohibit non-iterable containers to be passed as array input
Decode numeric zeros with correct scale
Fix handling of OIDs >= 2**31
Make Pool.close() wait until all checked out connections are released
Fix type codec cache races
Raise a consistent exception on input encoding errors
asyncpg v0.15.0
Behavior Changes
asyncpg no longer uses the common statement cache for explicit
prepared statements, so Connection.prepare() always returns a
new prepared statement
Bug Fixes
Initialize statement codecs immediately after Prepare
Fix server version parsing when it contains trailing data
v0.14.0:
Backwards Incompatible Changes:
asyncpg now reports the server version as x.0.y for PostgreSQL 10.0 and later.
This is in alignment with how upstream is interpreting the "minor" version
component now.
Improvements:
Support timeouts in Connection.close() and Pool.release()
Invalidate type cache on schema changes affecting statement result.
A new Connection.reload_schema_state() method.
Add CrateDB detection
Bug Fixes:
Make prepared statement uid generator global
Document pgbouncer-related prepared statement breakage
Fix unaligned access issues in host-network byte I/O on ARM
Fix issues with timetz type I/O
Consistently use postgres/postgres as database/user pair in tests

------------------------------
Drop support for PostgreSQL 9.1
Remove the deprecated "binary" parameter from Connection.set_type_codec()
New Features
------------
