 Whipper relies on the following packages in order to run correctly and provide all the supported features:
 
 - [cd-paranoia](https://www.gnu.org/software/libcdio/), for the actual ripping
+  - To avoid bugs it's advised to use `cd-paranoia` **10.2+0.94+2-2**
 - [cdrdao](http://cdrdao.sourceforge.net/), for session, TOC, pre-gap, and ISRC extraction
 - [python-gobject-2](https://packages.debian.org/en/jessie/python-gobject-2), required by `task.py`
 - [python-musicbrainzngs](https://github.com/alastair/python-musicbrainzngs), for metadata lookup
 - [python-mutagen](https://pypi.python.org/pypi/mutagen), for tagging support
 - [python-setuptools](https://pypi.python.org/pypi/setuptools), for installation, plugins support

 - [python-requests](https://pypi.python.org/pypi/requests), for retrieving AccurateRip database entries
-- [pycdio](https://pypi.python.org/pypi/pycdio/) (to avoid bugs please use `pycdio` **0.20** & `libcdio` >= **0.90** or, with previous `libcdio` versions, `pycdio` **0.17**), for drive identification (required for drive offset and caching behavior to be stored in the configuration file)
+- [pycdio](https://pypi.python.org/pypi/pycdio/), for drive identification (required for drive offset and caching behavior to be stored in the configuration file).
+  - To avoid bugs  it's advised to use `pycdio` **0.20** or **0.21** with `libcdio` ≥ **0.90** ≤ **0.94**. If using `libcdio` **0.83**, which is _too old_ to satisfy all the requirements of whipper, just stick to `pycdio` **0.17**. Altough it needs additional testing, `libcdio` **2.0.0** seems to work fine if used with `pycdio` **2.0.0**. All other combinations aren't guaranteed to work.
 - [libsndfile](http://www.mega-nerd.com/libsndfile/), for reading wav files
