Varnish 3.0 发布第二个 beta 测试版本，主要改进包括：
- 文档更新，特别是在标准 VMOD 方面
- varnishncsa now ignores piped requests, since there's generally too
little information for us to do anything sensible with them.
- the VCL compiler is now stricter in enforcing no duplication of backends or probes.
statscommand has been removed from the CLI interface as it did not work well with the new dynamic counters.
- VCL now has
vcl_finifunctions that are called when a VCL is loaded or unloaded. This can be used for initialising VMODs.
