This release introduces a new, faster implementation for `groupby.apply`, as well as many performance fixes related to improving asynchronous execution, a new namespace for accessing experimental functions (for example, `DataFrame.modin.to_pickle_distributed`), a fix for a long-standing problem with the use of Modin objects inside UDFs for `apply` and many other fixes.
**Note:** to get Modin on MPI through unidist (as of unidist 0.5.0) fully working by installing with pip it is required to have a working MPI implementation installed beforehand.
