[Paraview-developers] Update: Upcoming ParaView Releases (4.4 and 5.0)

[Schlottke-Lakemper, Michael]

Hi Utkarsh,

For those of us maintaining our own ParaView builds (and also our own set of custom-built plugins), it would be great if you can provide a document specifically outlining breaking changes in v5.0 for the Plugin API, differences in required library versions or different flags for compiling ParaView etc. Comments on changes for compiling with OSMesa (if any) are also welcome.

Other than that, kudos for following the dual approach with releasing 4.4/5.0 simultaneously. This is certainly going to make things much easier for us in the transition process, as it allows us to verify if things breaking on our side are due to new features or due to the new backend.

Regards,

Michael

Folks,

Since we're getting close to the next release, I just wanted to send out an email to let everyone know how we're planning to do the next release.

+ We'll do a ParaView 4.4 release will all features/fixes planned for the next release. This will use the older rendering code (same as previous release) that doesn't using OpenGL 2+ features.

+  Following the same pattern as VTK, soon after (at the same time, if possible), we'll release ParaView 5.0. This will be ParaView 4.4 but with OpenGL2 backend.

The main reason for this separation would be to have a fallback in case showstopper issues are noticed with the major rendering changes and for legacy systems that don't have a newer OpenGL.

Any thoughts? Comments? Suggestions? If things go according to plan, release candidates should start popping up mid/late August.

p.s. Originally, we also intended to upgrade ParaView 5.0 to use Qt 5, by default. However, there are a few outstanding issues with Qt 5 (some in Qt 5 itself, and some in our testing code) and hence the upgrade to Qt 5 has been tabled for now.
