<p>The MapServer Team is pleased to announce the release of MapCache 1.4</p>
<p>This 1.4 release brings a number of major new features that are summarized in
this document.</p>
<ul class="simple">
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-rest"><span class="std std-ref">REST Caches</span></a></p>
<ul>
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-rest-s3"><span class="std std-ref">Amazon S3 REST Caches</span></a></p></li>
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-rest-azure"><span class="std std-ref">Microsoft Azure REST Caches</span></a></p></li>
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-rest-google"><span class="std std-ref">Google Cloud Storage REST Caches</span></a></p></li>
</ul>
</li>
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-meta"><span class="std std-ref">Meta Caches</span></a></p>
<ul>
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-composite"><span class="std std-ref">Composite Caches</span></a></p></li>
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-fallback"><span class="std std-ref">Fallback Caches</span></a></p></li>
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-multitier"><span class="std std-ref">Multitier Caches</span></a></p></li>
</ul>
</li>
<li><p>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: <a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-sqlite"><span class="std std-ref">SQLite Caches</span></a>.</p></li>
<li><p><a class="reference internal" href="../../mapcache/caches.html#mapcache-cache-riak"><span class="std std-ref">Riak Caches</span></a></p></li>
<li><p><a class="reference internal" href="../../mapcache/proxying.html#mapcache-proxying"><span class="std std-ref">Proxying Unsupported Requests</span></a> now supports POST requests (apache module only)</p></li>
<li><p>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:
<a class="reference internal" href="../../mapcache/locks.html#mapcache-locks"><span class="std std-ref">Locking Mechanisms</span></a></p></li>
<li><p>WMS GetMap requests may now override the default image format: <a class="reference internal" href="../../mapcache/services.html#mapcache-getmap-format"><span class="std std-ref">GetMap Image Format</span></a></p></li>
<li><p>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): <a class="reference internal" href="../../mapcache/config.html#mapcache-config-tileset"><span class="std std-ref">tileset->use_wms_intermediate_resolution</span></a></p></li>
<li><p>Support for worldwind layout of disk stored tiles</p></li>
<li><p>Forward headers to backend WMS servers: <a class="reference internal" href="../../mapcache/config.html#mapcache-config-source"><span class="std std-ref">Source</span></a></p></li>
<li><p>Seeder can log failed seeded tiles, and can replay previously logged failed tiles.</p></li>
