The Ultra Release

Some more notable additions to pySDC, in particular :

• (yet) some others improvements on CI thanks to @jakob-fritz (#477, #478)
• minor improvements and bugfixes thanks to @brownbaerchen (#479, #480, #482, #484, #485, #486, #487)
• project update for the first revision of the parallel SDC theory paper thanks to @tlunet (#481, #488)
• 🚀 implementation of a first standalone spectral discretization framework for the problem classes (Fourier, Chebyshev, Ultraspherical) thanks to @brownbaerchen (#476)

And cherry on top, a brand new release guide for maintainers in the contribution guidelines.

Back-to-school release

A new minor release to start the new season, including

• some fixes (#449, #452, #465, #468), migration to scipy (#449), new HPC infrastructure for resilience scripts on JUSUF (#451), new plots from a paper review (#467) and some more GPU porting (#469) thanks to @brownbaerchen
• improvements on DAE parts (#450, #455, #460, #463) thanks to @lisawim
• many fixes and improvements on the CI pipeline (#456, #457, #459, #461, #462, #466, #470, #475) thanks to @jakob-fritz
• instructions to install with pip+git (#471) thanks to @BenjaminRodenberg (first contribution 🚀)
• a brand new playground to mix pySDC and dedalus thanks to @tlunet

Feels like a busy start !

The summer cleanup release

This release brings major cleanup of the code base, moving all quadrature-based stuff to the newly developed qmat library. We also have more examples, more sweepers, more CI, more consistency in the naming scheme and more more. See the changelog for (a bit) more details.

Another preparatory release

In this release a lot of cleanup happened, including much better documentation. pySDC learned about new time-steppers and now has even more projects to play with. Thanks to @brownbaerchen, @tlunet, @lisawim, @ikrom96git.

The preparatory release

This release mainly provides changes under the hood to prepare for Version 6 of pySDC. More in the release notes.

The Documentation release

This version marks significant changes in the documentation and a few key updates in terms of functionality. See the changelog for more details! Thanks to @brownbaerchen, @tlunet, @lisawim!
