+h3. WebDAV service uses @/var/cache@ for file content
+
+@keep-web@ now stores copies of recently accessed data blocks in @/var/cache/arvados/keep@ instead of in memory. That directory will be created automatically. The default cache size is 10% of the filesystem size. Use the new @Collections.WebDAVCache.DiskCacheSize@ config to specify a different percentage or an absolute size.
+
+If the previously supported @MaxBlockEntries@ config is present, remove it to avoid warning messages at startup.

 h3. Check MaxGatewayTunnels config
 
 If you use the LSF or Slurm dispatcher, ensure the new @API.MaxGatewayTunnels@ config entry is high enough to support the size of your cluster. See "LSF docs":{{site.baseurl}}/install/crunch2-lsf/install-dispatch.html#MaxGatewayTunnels or "Slurm docs":{{site.baseurl}}/install/crunch2-slurm/install-dispatch.html#MaxGatewayTunnels for details.
