Changelog

Notable Formalint updates and site quality changes.

October 13, 2026 - SQL Error Output Consistency

Failed Compact and Check actions now replace stale results with the current SQL input, matching Format. Copy, download and metrics remain consistent with the failed input. Added regression coverage and documented error examples and formatter limitations.

October 4, 2026 - XML Conversion Data Preservation

Fixed XML to JSON conversion dropping CDATA and special element or attribute names such as __proto__. Adjacent text is concatenated without invented spaces, and text-only values retain surrounding whitespace. Added mapping examples, mixed-content limitations and conversion regression tests.

October 2, 2026 - Regex Flag and Unicode Corrections

The regex matcher now respects the global flag, advances empty Unicode matches by code point, clears stale metrics on invalid input and labels the 200-match display limit. The email sample starts with multiline matching enabled. Added reproducible flag examples and automated regression tests.

October 1, 2026 - Email Validation Consolidation

Consolidated three overlapping email-regex references into the maintained Email Regex Validator. Added the JavaScript implementation and policy boundaries to the primary page, pointed legacy references to it with canonical tags, removed duplicate discovery cards and sitemap entries, and taught the sitemap generator to exclude canonicalized or noindex pages.

September 30, 2026 - Search Quality and Core Intent Update

Paused library expansion after a content-quality audit and improved four established search destinations: Regex Matcher, Email Regex Validator, XML Linter and SQL Cleanup.
