Major breaking changes are planned for WFDB v4. We plan to release v4.0.0 in August 2022. Live list of notable changes:

• The processing and plot dependencies will no longer be installed by default. They will have to be installed as extras via: pip install "wfdb[plot,processing]" (now planned for v5)

• Specifying read/write sources for WFDB data will be different for rdrecord, rdsamp, wrsamp, rdann, and wrann.

• Import paths for several conversion functions will be different

• rdrecord/rdsamp will no longer support reading edf and wav files.

• The <format>2mit functions will be renamed to <format>_to_wfdb. See this note.
