Increment version

v2.0.3 - Purge bugfix

Hotfix release

Fixes issue with partial cache entries and stale-while-revalidate headers serving broken responses.

v2.0.0: Merge pull request #158 from hamishforbes/master

Fixes for metadata transaction abort

v1.28

• Fixed issue where Surrogate-Capability parser incorrectly looked for our current host name to match (thanks @hamishforbes)
• ORIGIN_MODE_AVOID now properly ignores request validators

v1.27.3

• Fixed issue where local validation would pass if a validator was present but respective Etag or Last-Modified was not (local validation should always fail in this case). Thanks @hamishforbes

v1.27.2

• Fixed issue where partially evicted entries could be served rather than revalidated

v1.27.1

• Fixed error handling to prevent the qless purge job from failing batch work

v1.27

Features

• Major data structure refactor to reduce the number of keys. If you wish to retain cache on upgrading, you must run migrations/1.26-1.27.lua
• Introduced support for RFC5861 to control and improve stale content semantics
  Note: The old max_stale and stale_if_error configuration options have been removed, setting them will do nothing - use the Cache-Control extensions described in RFC5861 instead
• Range requests which go upstream (fetching a partial yet cacheable response), will now trigger a background revalidation for the complete resource
• Fixed no-cache=HEADER implementation (thanks @hamishforbes)

Tweaks

• Added code coverage tests
• All Redis keys for a cache entry are now touched on read, to help with LRU accuracy
• Removed old (unused) state machine entries revealed by coverage tests
• Changed all state machine events to be tail calls
• We now return 525 in the event of SSL handshake failure (previously the request would be attempted on a closed socket)
