[Stir-devel] STIR 6.4.0 released

[Kris T. <k.t...@uc...>]

Dear all

You might have noticed that STIR 6.4.0 was released last week.

This is a release with an important TOF bug fix, considerable improvements in the Python interface, support for libparallelproj 2, speed-up in CUDA code and normalisation code, example/documentation improvements (including an example script to process Siemens Quadra data from e7tools output).
We're especially happy to report that Quadra reconstructions are of similar quality as the e7tools ones, with of course more options than OSEM available. Memory requirements are relatively modest, but the more cores you have, the better 🙂. Note however that GPU (via parallelproj) reconstructions of Quadra data are still work-in-progress.
Full release notes are at Release v6.4.0 · UCL/STIR<https://github.com/UCL/STIR/releases/tag/rel_6.4.0>. Build instructions are as usual, but easiest install is via conda<https://github.com/UCL/STIR/wiki/Installing-STIR-with-conda>.
Many thanks to Zekai Li (UMCG), Denis Prokopenko (KCL), Nicole Jurjew (UCL), Markus Jehl (Positrigo),  Dimitra Kyriakopoulou (Academy of Athens) for code contributions. Thanks also to Christian Hinge (U Copenhagen) for additional testing of Quadra reconstructions.
There's lot of exciting things coming to STIR in the near future, but in the mean time, enjoy this release!
