Summary of changes from 2.1.3 to 2.1.4

    * A bug in the binary heap layout caused inflated object counts, this has \ 
been fixed.
    * Much more comprehensive documentation.
    * A DNS director that uses DNS lookups for choosing which backend to route \ 
requests to has been added.
    * The client director now uses the variable client.identity for choosing \ 
which backend to send a given request to.
    * String representation of now, making it easier to add Expires headers
    * Portability fixes for Solaris.
    * Various bug fixes.

Summary of changes from 2.1.2 to 2.1.3

    * The scalability of critbit, the default hashing method, has been improved.
    * A bug in varnishd would in some cases confuse varnishncsa leading to lost \ 
or wrong log lines.
    * Some bugs in the handling of Range requests has been fixed. This only \ 
matters if you enable Range support.
    * Add «log» command to VCL which will log to the Varnish log.

Summary of changes from 2.1.1 to 2.1.2

    * When adding Range support in 2.1.1 an error was introduced. Garbage was \ 
appended to some objects. This affected some load balancers - but clients seemed \ 
not to be affected.

    * Experimental support for the Range header, must be enabled with the \ 
http_range_support parameter.

situations. This is now fixed.

    * Support for completely obliterating objects including all variants \ 
(«nuke»). See http://varnish-cache.org/changeset/4668 for details

Summary of changes from 2.0.6 to 2.1.0

Varnish 2.1.0 has just been released. It contains lots of changes relative to \ 
2.0.6, the most important ones being:

    * Experimental support for persistent cache
    * The regular expression engine is now PCRE
    * Saint mode, where we can serve a cached object if the backend is down or \ 
otherwise faulty.
    * A more scalable hashing method called critbit
    * Increased scalability, removing a limitation of maximum 64k connections
    * obj_workspace is removed, this is now scaled automatically
    * Hashing and client IP based directors
