BREAKING CHANGE

With the advance of the BSUP format to v2, super will no longer read BSUP v1 format as input. There is currently no backward compatibility in super for reading BSUP v1 inputs. If you have valuable saved BSUP v1 files that you cannot easily regenerate into v2 from their original sources, please speak up on community Slack or open an issue for assistance.

Added

• New debug operator (#6685, #6694, #6680, #6691, #6726)
• New infer operator (#6704)
• New defuse function (#6698)
• New unblend function (#6725)
• New db vacate command (#6706, #6747)
• Fusion types (#6713)
• Named types in upcast function (#6752)
• Optional fields in record expressions (#6702)

Changed

• Change license to SuperDB Source Available License v1.0 (#6755)
• In collect and union aggregate functions, error("quiet") values are now dropped and error("missing") values are preserved (#6710)
• null values are now ignored in concat function and f-strings (#6730)
• macOS super release artifacts are now signed and notarized (#6703)
• The BSUP format has been advanced to version 2 (#6713)

Fixed

• Fix unnest bug when to-be-unnested array is in a union (#6692)
• Fix precision bug when casting from float16 or float32 to string (#6722)

BREAKING CHANGE

With the advance of the BSUP format to v1, super will no longer read BSUP v0 format as input. There is currently no backward compatibility in super for reading BSUP v0 inputs. If you have valuable saved BSUP v0 files that you cannot easily regenerate into v1 from their original sources, please speak up on community Slack or open an issue for assistance.

Added

• New upcast function (#6634)
• Line numbers are now shown for SUP parsing errors (#6630)
• Optional fields in records (#6669)

Changed

• Upgrade to github.com/apache/arrow-go/[email protected] (#6625)
• Type fusion now ensures any fused unions contain at most one instance of each kind of complex type (#6651)
• Type decoration for self-describing error values in SUP are now omitted (#6656)
• By default, super now reads the first 1000 values when reading from an input file to infer type information used to type check the query. This can cause type errors when data being referenced occurs later in the input. The -samplesize flag can be used to adjust this. (#6667)
• The BSUP format has been advanced to version 1 (#6674)

Removed

• Typed nulls are no longer supported, with nullable values now represented with a union that includes type null (#6633)

Fixed

• vam: Casting an error value now propagates the error (#6602)
• vam: Fix an issue where a mixed type error was not returned if the aggregation received a number first followed by a string (#6618)
• vam: Fix a rename operator issue where nested records were not getting assigned updated types (#6623)
• Fix a deadlock that could occur when running a group-by aggregation on BSUP input (#6624)
• The BSUP union tag is now encoded as a uvarint, in line with the specification (#6660)
