Changelog
Material changes to calculations, sources and user-facing behavior.
Re-audited high-impact data and added the vehicle-tax surcharge
- Corrected the disclosed Ft period to September–December 2026 while keeping 16.23 satang per unit, with a 150-unit regression example.
- Pinned all 20 BOT financial-institution holidays including the Bangkok-only date and stopped invalid, out-of-year and duplicate dates from inflating leave counts.
- Rechecked income tax, withholding, VAT, the Section 33 wage base and SSO rounding evidence, adding source metadata and regression tests.
- Added the 1% per month-or-part late vehicle-tax estimate from a user-confirmed count without guessing compulsory-insurance fines or covering vehicles unpaid for three years.
- Re-opened the invoice, receipt, billing-note and delivery-note sources, added the Section 105 quater delivery-note scope and covered impossible dates and text limits with regressions.
- Updated review dates only for tools whose primary sources were actually opened; unrelated dates were not moved in bulk.
- Added eight Thai/English journeys, bringing the catalog to ten distinct multi-tool workflows across debt, freelance work, web publishing, files, Thai text, dates, sharing and property.
- Completed the editorial review of all 88 medium- and low-risk English pages, replaced low-value suite placeholders and added regression coverage.
Corrected severance evidence and added a Section 118 guide
- Replaced a Ministry summary still capped at 300 days with the consolidated Act supporting 400 days for 20+ years.
- Added scoped source metadata and a regression test for the effective date, review date and highest bracket.
- Added a Thai/English guide separating service-bracket arithmetic from eligibility, exclusions and special compensation.
- Corrected stamp-duty rounding per THB 200 or part and the sale-price basis for the supported individual-withholding cap without generalising a condominium-specific minimum.
First developer, image, business, government and analytics backlog tranche
- Added a URL parser, NIST-aligned password readiness checker and live HTTP status checker with SSRF controls, a timeout and no redirect following.

- Expanded local image output to WebP, JPG or PNG with explicit transparency handling and MIME verification.
- Added visible-content HowTo/FAQ semantic markup and English breadcrumbs without claiming rich-result eligibility.
- Added privacy-safe favorite, share, related-tool and guide-click events.

- Added thirteen Thai/English tools covering hashes, regex, JWT decoding, text diffs, YAML, XML, HTTP statuses, UTM links, meta tags, schema, robots.txt and sitemap.xml.
- Processing stays on the device with input limits and a timeout worker for regex. The JWT tool decodes data without claiming to verify signatures or claims.
- Documented W3C, IETF, IANA, ECMA, WHATWG, Schema.org, YAML and Sitemaps sources with risk, review dates, specifications and tests.
