Changelog

Notable Formalint updates and site quality changes.

August 27, 2026 - Resource Hub Update

Expanded Formalint from a tool collection into a stronger developer resource hub. The home page now shows quality signals, operating principles, a reference library, maintained-site indicators and clearer routes into high-value guide content. Added long-form guides for developer data validation and formatter/linter/validator decisions.

August 27, 2026 - Content Quality Update

Added cornerstone guides for regex, data formats and API debugging. Added transparency pages for editorial policy, local-first behavior and changelog visibility. Improved the home page structure so Formalint reads more clearly as a developer tools and reference site.

July 28, 2026

Added focused regex references for email validation, URL validation, UUID v4 validation, date validation and log parsing. Updated Search Console-oriented internal links and sitemap entries.

July 2026

Added XML linting, YAML indentation, SQL cleanup and Python indentation references. Expanded the developer tools directory and strengthened cross-links between related tools.

Earlier 2026

Launched the core Formalint toolkit with JSON formatting, XML formatting, YAML cleanup, SQL formatting, Python snippet cleanup, Regex testing, JWT decoding, Base64, URL encoding, hashing, timestamps, cron parsing, UUID generation, color conversion and CSV to JSON conversion.

Quality Direction

Future updates should continue to pair tools with practical examples, clear limitations, safe sample handling notes and visible author/contact information.
