OpenACS Core 5.3.0 Beta 1 has been released

OpenACS Core 5.3.0 Beta 1 has been released, and is available for downloading now. All automated tests for the core packages pass when using PostgreSQL. A few tests fail for Oracle, but are minor. At least six production sites are running on the alpha release of 5.3.0, and the oacs-5-2 branch of .LRN packages appear to run fine with 5.3.
