Release Notes - SABnzbd 4.0.0 Alpha 2

Changes since 4.0.0 Alpha 1

  • There are now multiple settings that can tweak performance, see: 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!

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!
  • 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.
  • HTTPS files are included in the Backup.
  • Improved Watched Folder scanning and processing.
  • Dropped support for Python 3.7.

Bugfixes since 3.7.2

  • Restore applying History Retention setting at startup.
  • Windows: Not all invalid characters were removed from filenames.

Upgrade notices
