The MapServer Team is pleased to announce the release of MapCache 1.4

This 1.4 release brings a number of major new features that are summarized in this document.

• REST Caches

  • Amazon S3 REST Caches

  • Microsoft Azure REST Caches

  • Google Cloud Storage REST Caches

• Meta Caches

  • Composite Caches

  • Fallback Caches

  • Multitier Caches

• Sqlite caches now support custom schemas, and database files can be organized to e.g. contain a single tileset or grid, and can be configured to distribute tiles across multiple database files: SQLite Caches.

• Riak Caches

• Proxying Unsupported Requests now supports POST requests (apache module only)

• Locks used for synchronizing mapcache instances can now be stored in memcache, and have a configurable timeout to prevent deadlocks in case of killed instances: Locking Mechanisms

• WMS GetMap requests may now override the default image format: GetMap Image Format

• Intermediate/Hidden grid levels can be used to create higher quality resampled GetMap images, at the cost of higher tile storage (à la MapProxy’s sqrt2 tiles): tileset->use_wms_intermediate_resolution

• Support for worldwind layout of disk stored tiles

• Forward headers to backend WMS servers: Source

• Seeder can log failed seeded tiles, and can replay previously logged failed tiles.
