Release Notes - SABnzbd 4.0.0 Release Candidate 2

Changes since 3.7.2

In this major update we replaced a core part of Python's SSL handling
with our own improved version. This results in large performance increases
when downloading from news servers with SSL enabled.
In addition, the general connection handling was overhauled, resulting in
performance improvements for all news servers.
Special thanks to: mnightingale, puzzledsab and animetosho!
There are multiple settings that can tweak performance, see:
sabnzbd/sabnzbd#2474
We are trying to find the most optimal default settings, so you
can help us by letting us know the results on your system!
When adding a new news server, SSL is enabled by default.
File assembly performance significantly improved by relying on the
CRC32 instead of the MD5 to perform QuickCheck of files.
Slowdown more gracefully when the cache fills up.
Replaced separate Series/Movie/Date Sorting with general Sorter.
HTTPS files are included in the Backup.
Improved Watched Folder scanning and processing.
Ignore resource fork files created by macOS.
Deobfuscate final filenames is enabled for new installations.
Dropped support for Python 3.7.
