Dear OpendTect users,

We have made a patch release for our previous stable version: OpendTect 6.4.6, which is now available for installation/update on Windows and Linux.

OpendTect patch release 6.4.6

This special maintenance release addresses compatibility issues with the current stable release 6.6 and various security issues. It is possible that after the upgrade older versions of the F3 and Penobscot surveys will not be recognized as license-free. If that happens, please download the latest version of these projects from Terranubis. Please be informed that we added more free data sets that will not check for license keys. These data sets, which are also downloadable from TerraNubis, can thus be used for R&D and testing OpendTect Pro and the commercial plugins.

The new version of OpendTect comes with updated license management executables (lmgrd, lmutil, dgbld) in FlexNet v11.18.1. OpendTect v6.4 will continue to be fully compatible with all license daemon versions down to v11.15.1. Nevertheless, it is strongly recommended to replace on your license server the executables listed above by the newer FlexNet versions provided in this release. The latest FlexNet version for all platforms can always be downloaded from the flexnet vendors packages download page. These versions are updated regularly.

To install or update to the new version, either use the 'Installation -> Update' option from the Utilities menu in OpendTect-6.4 or download the Installation Manager from our download center, and ensure to select the release "OpendTect 6.4 (Previous)".

For a list of improvements and bug-fixes that are included in the 6.4.6 release, please refer to the online release notes for OpendTect and the dGB plugins.
