# The `compression` package

Added in version 3.14.

The `compression` package contains the canonical compression modules containing interfaces to several different compression algorithms. Some of these modules have historically been available as separate modules; those will continue to be available under their original names for compatibility reasons, and will not be removed without a deprecation cycle. The use of modules in `compression` is encouraged where practical.
