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

0.4: Implement Serialize/Deserialize for Many

Support Serialize/Deserialize for Many
This required changing the Query/Expr structures, and so is technically a breaking change.

0.3.1

Add the #[unique] model field attribute. This can be used to add a UNIQUE constraint on the field.
