--   July 28, 2023: For Version 5.3 a lot of pull requests got merged, thanks to [\@brownbaerchen](https://github.com/brownbaerchen),
-    [\@tlunet](https://github.com/tlunet), [\@lisawim](https://github.com/lisawim), [\@ikrom96git](https://github.com/ikrom96git) for all the contributions.
-    Besides the usual bugfixing and polishing, `pySDC` now comes with linear multistep methods, classical Runge Kutta methods, DAE sweepers, and more/improved projects.
-    We have second-order SDC on board, the brand-new switch estimator, a testing ground for compression with [libpressio](https://github.com/robertu94/libpressio), and more.
--   March 24, 2023: Version 5.2 is out and improves the code in multiple directions. The problem class can now define their 
-    parameters explicitly with the constructor, and not with a dictionary. `params` is now a property of the problem class, that returns the problem parameters into a dictionary,
-    and parameters are also automatically stored as problem attribute using the `_makeAttributeAndRegister` method, allowing to define readonly paramters
-    (warning: **not backward compatible**).
-    The resilience project now comes with the quench problem, resulting a collaboration between @brownbaerchen and @eschnaubelt during the 
-    TIME-X Apps Hackathon at USI Lugano. Many of the other changes under the hood prepare `pySDC` for Version 6.
--   January 23, 2023: Version 5.1 brings a lot of changes to the documentation, both on Github and on the website. 
-    We revived the [codecov](https://app.codecov.io/gh/Parallel-in-Time/pySDC) connection and started the 
-    [OpenSFF Best Practices](https://bestpractices.coreinfrastructure.org/en/projects/6909) guide. 
-    The hook classes and the way they are handled has changed (without breaking the API, hooray), the battery model 
-    got quite an update and adaptivity plays a more prominent role now. Thanks to [\@brownbaerchen](https://github.com/brownbaerchen),
-    [\@tlunet](https://github.com/tlunet), [\@lisawim](https://github.com/lisawim)!
--   October 7, 2022: Version 5 comes with many changes, both visible and
-    invisible ones. Some of those break the existing API, but if you are
-    using tests, you should be fine. Major changes include:

     -   **New convergence controllers**: Checking whether a step has
         converged can be tricky, so we made separate modules out of
