Release 2.3.0

[bgunebakan]

Changes

Added

• CrateDB column type identifiers in DataType: INTERVAL (17), ROW (18), FLOAT_VECTOR (28), UUID (29), and REGTYPE (30). (Fix ValueError on unlisted CrateDB column type identifiers #830)

Fixed

• Converter.get() raised ValueError for column type identifiers it does not know. Unknown identifiers now fall back to the default converter, so queries on columns using newer CrateDB types no longer fail. (Fix ValueError on unlisted CrateDB column type identifiers #830)

Behavior changes

• connect() now raises ConnectionError immediately if no configured server node responds, instead of deferring the error until the first statement is executed. Code that creates a connection eagerly, before the cluster is reachable, needs to handle the error at connect() time. (Fix: Fail early when database cluster does not respond #711)
• DefaultTypeConverter now decodes DataType.BIT columns, converting CrateDB's B'0110' wire format to a plain string of 0/1 digits. Code that stripped the wrapper itself needs to be adjusted, or can restore the previous behaviour by mapping DataType.BIT to a converter of its own. (Fix Register converter for DataType.BIT #828)
• DefaultTypeConverter now decodes DataType.UUID columns to Python uuid.UUID objects instead of returning the raw string. Code that expected a string can call str() on the value, or map DataType.UUID to a converter of its own.

Both converter changes only affect code that opts into DefaultTypeConverter; the default Converter is unchanged.
