1.0.0 (2026-02-13)#

Initial stable release of MilliCache — a full-page cache plugin for WordPress powered by Redis compatible servers.

Highlights#

  • In-Memory Full-Page Cache — Pages are served directly from memory before WordPress even initializes. No database queries.
  • Flag-Based Invalidation — Tag cached pages with flags like post:123 or archive:category:5, then clear related entries with a single command. Built-in flags are assigned automatically; custom flags give you full control.
  • Stale-While-Revalidate — Serve expired content while fresh content regenerates in the background. Prevents cache stampedes on high-traffic pages.
  • Rules Engine — Define caching behavior with a fluent, chainable PHP API. Set TTL, grace periods, and exclusions per condition — all version-controllable.
  • Multisite Native — Per-site cache isolation with network-wide management. Clear one site, a subset, or an entire network.
  • Multiple Backends — Redis, ValKey, KeyDB, or Dragonfly. Any Redis-compatible server works out of the box.
  • WP-CLI Integration — Commands for cache testing, status checks, diagnostics, and bulk operations. AI-agent friendly.
  • Debug Headers & Browser Extension — X-MilliCache-* headers show cache status, flags, and keys. The companion browser extension makes debugging effortless.
  • REST API — /millicache/v1/* endpoints for cache control, status checks, and settings — ideal for CI/CD pipelines and monitoring.
  • Action & Filter Hooks — Full customization of caching behavior, flag assignment, and invalidation events.
  • Smart Auto-Invalidation — Cache clears automatically when posts, menus, widgets, or theme settings change.
  • Open Source — GPL-2.0+ licensed. No vendor lock-in.
