Release Notes

coleifer/peewee (peewee)

v4.0.0

Compare Source

• Adds preliminary support for asyncio via a new playhouse extension. See
  the documentation
  for details.
• PostgresqlDatabase can use psycopg (psycopg3) if it is installed. If both
  psycopg2 and psycopg3 are installed, Peewee will prefer psycopg2, but this
  can be controlled by specifying prefer_psycopg3=True in the constructor.
  Same applies to PostgresqlExtDatabase.
• Psycopg3Database class has been moved to playhouse.postgres_ext and is
  now just a thin wrapper around PostgresqlExtDatabase.
• Postgres JSON operations no longer dump and try to do minimal casts, instead
  relying on the driver-provided Json() wrapper(s).
• Adds new ISODateTimeField for Sqlite that encodes datetimes in ISO format
  (more friendly when db is shared with other tools), and also properly reads
  back UTC offset info.
• Remove playhouse.sqlite_ext.ClosureTable implementation.
• Add a Model.dirty_field_names attribute that is safe for membership
  testing, since testing x in dirty_fields returns True if one or more field
  exists due to operator overloads returning a truthy Expression object.
  Refs #​3028.
• Removal of Cython _sqlite_ext extension. The C implementations of the FTS
  rank functions are moved to sqlite_udf. Most of the remaining functionality
  is moved to playhouse.cysqlite_ext which supports it natively.

Migrating CSqliteExtDatabase usage:

You can either use sqlite_ext.SqliteExtDatabase or try the new
cysqlite_ext.CySqliteDatabase if you want all the old functionality and are
willing to try a new driver.
