This release adds error recovery mechanisms, in order to access erroneous datasets, created e.g. by crashing simulations. The BP5 engine of ADIOS2 v2.9 is fully supported by this release, including access to its various features for more fine-grained control of memory usage. Various I/O performance improvements for HDF5 are activated by default. Runtime configuration of openPMD and its backends, e.g. selection of backends and compression, is now consistently done via JSON, and alternatively via TOML for better readability. The data storage/retrieval API now consistently supports all common C++ pointer types (raw and smart pointers), implementing automatic memory optimizations for ADIOS2 BP5 if using unique pointers.

The miminum required C++ version is now C++17. Supported Python versions add Python 3.10 and 3.11.
