The next release, which has been announced for the end of this month, is already in beta testing (I know, I'm already using it). The beta version works pretty well, with just a couple of minor blips to sort out.
Daniel Benito of Atril announced the build on the list at Yahoogroups a few weeks ago and wrote:
I'm sure all of you will be glad to know that we're about to release a new build of Déjà Vu X. In fact, there is so much new functionality in it that we're going from version 7.0 to 7.5. Among the new things you will find are:
- Full support for Windows Vista
- Support for the new Office 2007 XML formats
- Support for Adobe InDesign CS2 INX
- Support for OpenOffice 2.0 (OpenDocument)
- Support for SDLX ITD files (in projects)
- Support for RESX (.NET resources)
- Support for our new TM Server
- Importing MultiTerm termbases
- Importing SDLX translation memories
In addition to that, we have improved a number of existing features, especially Assemble and Propagate.
We are currently at build 7.5.295, which is being tested internally. A beta build will be released before the end of the week and will be made available to beta testers, and newer beta builds will be released as testing progresses. Version 7.5 will be released on March 30th.
In parallel, we are working on the release of our TM Server - a centralized, SQL-based translation memory and terminology server which will integrate seamlessly with Déjà Vu X 7.5 and provide robust sharing and storage capabilities to larger groups of translators, beyond what the current COM+ based
server can do. The scheduled release date for the TM Server is April 27th.
