The release 6.5.3 of OCCT libraries has been planned for the end of March.
Taking into account the needs of our projects (SALOME first of all) we are going to delay the release by about two weeks; this time will be needed to complete testing and verification of the important fixes made for the projects.
Anyway, most of the changes are already certified and integrated, so we consider current version as ready for beta-testing, and invite you to test this version in your applications. If you had reported some issues in Mantis bug tracker, please check those having Verified status -- we assume they are fixed, and will appreciate to see your comments in the notes of the issue.
Please use the commit tagged "V6_5_3_beta1" in the Git master branch for this testing. If you do not have direct access to the repository, you may download the archive of sources from GitWeb (just click on the "snapshot" link).
For the users who are not ready to build from bare sources with WOK, we are going to prepare standard source package containing pre-processed sources and build tools. This package will be published on www.opencascade.org.
