A completely new version where I stop trying to fix upstream data myself and remove all the bad legacy code, resulting in many breaking changes.

It has become too annoying to constantly check for upstream data changes, especially since some data is officially documented but often doesn’t get a version bump. In the case of PULS, "MobilePlan" exports are introduced mid-year, breaking half of this library (and their own documentation) from time to time.

All issues with upstream data will be labeled as such, and I’ll forward them to the respective company(s). It will then be their choice whether to fix the issues or not. However, please never expect data from the company "VAG" to be correct. From my observations over the past six years, it seems they never verify the accuracy of the information they publish. Their most accurate sources are https://www.vag.de/presse/aktuelle and the ticket shop page.

Other data comes from reverse-engineered sources, so I’ll focus on writing more stable parsers and implementing better error handling to detect and resolve issues faster.
