Release 0.6.0 (Aug 13, 2026)

Notable Changes

• Drop support for Python 3.8 and 3.9. Python 3.10+ is now required.
• IMPORTANT: Fixes a potential denial of service attack (DOS) in the lexer, which consumed CPU quadratically on statements containing many unclosed dollar-quoted literals or multiline comments (CVE-2026-59893). See the security advisory for details: GHSA-prg7-hcfm-mfcr The vulnerability was discovered by EQSTLab, min8282 and 7thpark. Thanks for reporting!
• IMPORTANT: Fixes a potential denial of service attack (DOS) when grouping deeply nested or very wide statements. Building a token group re-read the whole group on every step, so a small statement could keep a worker busy for a long time (CVE-2026-54284, pr848 by alhudz and tonghuaroot).
• IMPORTANT: Fixes a potential denial of service attack (DOS) in format(sql, reindent=True), which consumed CPU quadratically on long lists of tuples. See the security advisory for details: GHSA-cfqr-cjx5-5jcm
• IMPORTANT: Fixes a potential denial of service attack (DOS) on statements that consist only of comments (CVE-2026-71491). See the security advisory for details: GHSA-f2ff-p2ww-7p4p The vulnerability was discovered by @​sanktjodel. Thanks for reporting!
• IMPORTANT: Backslashes are now escaped in the python and php output formats. Without escaping, SQL containing a backslash could break out of the generated string literal (CVE-2026-59894). See the security advisory for details: GHSA-3496-9g83-7v6x The vulnerability was discovered by @​7thParkk. Thanks for reporting!

Enhancements

• Modernize type annotations in top-level API functions using PEP 585 and PEP 604 syntax.
• END FOR and END CASE are now recognized as keywords.

Bug Fixes

• Statement splitting was rewritten on a stack-based architecture. This fixes splitting of statements with nested BEGIN ... END blocks (issue845).
• Fix function grouping being skipped in CREATE TABLE ... AS SELECT statements when the as keyword is lowercase (pr867 by Osamaali313).
• Recognize ROW_FORMAT as a keyword so that ALTER TABLE ... ROW_FORMAT=... no longer merges the table name and the option into a single identifier (issue773, pr860 by apoorvdarshan).
• Recognize MATERIALIZED as a keyword so it is parsed and formatted consistently in CREATE MATERIALIZED VIEW statements (issue752, pr854 by
