0.8

The major feature in this release is async support. Turn it on using
the async feature. If you wish to use SQLite with async, you must
also enable async-adapter. Enabling pg automatically enables
async (but the Postgres backend may still be used with sync
methods, enabling async does not disable synchronous usage).

For more about async support, see the README

Breaking Changes

• In order to allow sync and async code to look as similar as possible
  for types and traits which do not otherwise need separate sync and
  async variants, several "Ops" traits have been introduced which
  contain methods split off from prior types and traits and must now
  be imported explicitly if you are not using the prelude (use butane::prelude::* or use butane::prelude_async::*). The Ops
  traits are:

  • DataObjectOpsSync / DataObjectOpsAsync (for use with DataObject)
  • QueryOpsSync / QueryOpsAsync (for use with Query, less commonly needed directly if you use the query! or filter! macros)
  • ForeignKeyOpsSync / ForeignKeyOpsAsync (for use with ForeignKey)
  • ManyOpsSync / ManyOpsAsync (for use with Many)

• The ConnectionManager struct has moved from butane::db::r2 to
  butane::db. It no longer implements ConnectionMethods as this was
  unnecessary due to Deref. The butane::db::r2 module is no longer
  public.

API Features

• Impl Deref for AutoPk (#302)
• Add deadpool support (#284)

Library fixes & internal improvements.

• SQLite operates under strict mode (#320)
• Use nanosecond granularity on sqlite timestamp cols (#316)
• Dont rely on serde being in scope (#314)
• Recognize more paths for String and Vec (#299)
• Addressed new clippy lints
• Dependency updates

Contributors to this release: John Vandenberg, James Oakley, João M. Martins

0.5.1

• Add try_get to DataObject. This returns a Result<Option<T>> rather than Result<T>. When it's expected that the object may not exist, this leads to slightly better ergonomics.
• Support Chrono DateTime<Utc> like NaiveDateTime

0.5

• Many::add now returns a Result, which will indicate an error if used with an uninitialized primary key.
• Dependency version updates and clippy bitrot
• Cleanup improvements to Postgres tests

0.4.3

Add butane CLI commands clear and collapse

• clear clears out all data from the database without affecting the schema
• collapse collapses all (applied) migrations into a single new migration.

0.4.2

• Add offset parameter to Query
• Fix BoolExpr::In handling
• Add Many::remove
• Allow a ForeignKey to refer to the same type
• Fix bug saving an object with an auto-pk and a Many field.

0.4.1

Add sqlite-bundled feature
