Hello Apache DataSketches PMC and Community,
This is a call for vote to release Apache DataSketches-python candidate
version 5.0.0-rc2
This will be the first stand-alone Python release, although continuing the
version numbering used when this portion of the project was bundled with
the C++ release.
This is also a major version release with several significant changes:
* Vastly improved API documentation via sphinx
* More pythonic API:
* __copy__ instead of C++-style copy constructors
* __str__ takes no arguments in all cases
* Moved from pybind11 to nanobind, which also requires c++17 internally
* Added new exact proportional to size sampling sketch, ebpps_sketch
* Fixed slowness with theta intersection
* Fixed incompatibility with Java's serialized empty frequent items sketch
* Removed default Kernel for density sketch (GaussianKernel is still
provided)
* Removed extra (largely transparent to users) wrappers around
density_sketch and tuple_sketch
Changes from rc1:
* Fixed object leaks with KernelFunction and TuplePolicy objects
* Fixed all __str__ methods to perform as intended
* Added NOMINSIZE to nanobind config, increasing performance at the cost of
a slightly larger wheel
