v0.1.0

Added

• Initial browser-local Rust and WebAssembly implementation for Unix/Vixie five-field cron expressions
• Visual and raw expression editors with common five-field presets
• English and Simplified Chinese descriptions and interface text
• IANA 2026c time-zone occurrence previews whose scheduling and selected-zone display share the bundled data, with DST-aware wall-clock evaluation and a visible data version
• Minute-boundary and page-resume refreshes that prevent stale occurrence previews
• Limits of 256 UTF-8 bytes per expression and 50 occurrences per request
• Public product scope, contract, maturity, release, maintainership, security, support, contribution, and community-governance documentation

Fixed

• Selected-zone timestamps now use the same bundled IANA data as schedule calculation instead of the browser host database
• Custom visual field values remain synchronized with the raw expression across language changes
• Occurrence columns remain fully visible across the single-column and two-column layout boundary
• Relative-time formatting handles the full signed 64-bit timestamp range without overflow

Security

• Expression parsing and schedule calculation remain in the browser-loaded WASM module
• Bounded expression and result sizes limit resource use from untrusted input
• The npm lockfile is restricted to HTTPS package URLs from the official npm registry

Known limitations

• Only five-field Unix/Vixie cron is supported
• Six- and seven-field expressions and L, W, #, +, and ? are rejected
• Quartz, AWS scheduling syntax, CLI, MCP integration, Agent Skill, hosted API, and published packages are not provided
