2008-10-08 Release candidate 1
We are happy to announce Varnish 2.0 Release Candidate 1, and are aiming for a 2.0 release in one week, on October 15th.
The release candidate can be downloaded from https://sourceforge.net/project/showfiles.php?group_id=155816
Since beta 2, most of the changes have been minor. Some highlights are:
- Correctness fixes for ESI
- Better MacOS X support
- Documentation fixes
- Handle out-of-resource situations better by sleeping a little bit if we run out of file descriptors.
2008-09-24 Beta 2 released
Hopefully the last beta before entering release candidate mode.. Get it from Sourceforge!
And, of course, please remember to report your issues here :-)

2008-08-15: Varnish 2.0 Tech Preview Now Available!
We have a bunch of new features we've implemented since 1.1.2, and we'd love you to check out, among others:
- ESI - Supporting only the sensible subset
- Saves objects past expiration date («grace»)
- Multiple storage file support
- URL-rewrites
- PURGE-support based on regular expressions also over HTTP
- Backend selection and load distribution
- Directors can select by any metric they prefer
- Incomplete support for 64k long shmlog records - planned finalised in v 2.0 Final
- Restarts, allowing you to try the transaction again if you don't like where you ended up.
- Race condition in kqueue acceptor fixed
- The hash string is now built by VCL, which means people can customize it
- We have both "purge_hash" and "purge_url" as a result
- The former allowing purges per vhost for instance.
- New and less jumpy thread pool sizing algorithm
- Swallow request body where necessary
- Handle PUT/POST with pass
- Better TCP shutdown in pipe mode
- Garbage collection of purge entries
- Spelled 'Authorization' correctly instead of 'Authentication' in default VCL
- Added parameter tuneability - remember to be careful when trying them out!
As this is not a final release, we also have some known issues:
- There is a race-condition during start-up, causing pages with a certain amount of traffic needing several tries to start. This is easy to spot if you keep an eye on varnishstat and see it receive requests, but not sending any to the clients
- There's a known crash error we've found during testing on Finn.no, and it seemingly occurs once a week: The Varnish Supervisor-process restarts the cache, but the cache content usually disappears.
- An error caused the sourcecode in the download link to not include all the tests you can run with varnishtest. The missing tests can be grabbed from SVN
- If the client sends a Connection: header and the VCL code deletes one or more HTTP headers, the wrong set of headers may be sent to the backend.
Please take the TP for a testdrive, and let us know what you think, and please remember to report your issues here :-)
