We have upgraded the Webcrossing server with the following change:
Attachments. We fixed an issue with tracking “enclosure reference counts.” It’s rather techy, but the brief explanation is that the Webcrossing server has the ability to attach (or embed, for images) the same attachment (enclosure) to multiple posts without actually duplicating the file. Only one copy of the file is maintained in the enclosures directory. There was a reference counting error which could cause an attachment file to be removed from the enclosures directory even if all posts using it had not yet been deleted. This would usually only be noticeable at sites which did custom scripting taking advantage of the feature.
The latest release version is now Webcrossing 6.4 source: 1675 2014-09-27.
We will be upgrading all hosted customers, and coordinate the upgrade timing as needed. The upgrade itself only requires a few minutes of site downtime.
All self-hosted customers with valid support and maintenance contracts can download this new version at no cost.
We recommend upgrading to the new version. If you are a self-hosted customer and have a valid support and maintenance contract, please contact support for access to the new server. If your support and maintenance contract has expired, please contact us to renew so we can provide you with this important update.
Also a reminder about our previous recent upgrades: Version 1673 2014-08-31 was released on September 8 and fixed attachment deletion and cluster attachment propagation issues. Version 1670 2014-04-25 was released on May 7, 2014 and fixed an important stability issue which, under certain circumstances, could cause a Webcrossing server process to silently quit, leaving the site unresponsive, and also added a new feature to allow guest users to visit sites licensed for a limited number of users (a so-called “seat license”).
The latest release includes all those fixes and enhancements.
