Release Notes - SABnzbd 5.1.0
=========================================================

This release brings a fundamental improvement to "Retry": instead of
re-downloading any files with missing data, only the articles that were actually
missing are fetched again. RSS got an overhaul under the hood, the interface is
refreshed, and we added quite a long list of of long-requested features and bugfixes.

##### New features in 5.1.0

* Refreshed the interface.
* When Retrying a job, only the actually missing articles are tried again.
  This only works for jobs downloaded in 5.1.0 (or newer).
* RSS items are now stored in the database instead of on disk.
* New RSS `Age` rule to filter jobs based on their age.
* Downloaded RSS items are cleared from the RSS database after 3 days.
* Added support for filename and path pattern matching to the `Cleanup List`.
* `Unwanted extensions` will also be removed after unpacking.
* Allow job setting changes directly from `Extra queue columns`.
* Added support for unpacking `.tar` files during post-processing.
* Improved anonymization of the logs when using `Show Logging`.
* Added `SAB_FILES` environment variable to Post-processing scripts,
  listing all files that resulted from the job.
* New Servers will default to 16 connections instead of 8.
* Use media duration as part of `Ignore Samples` detection.
* Added option to (auto) sort the queue by Remaining Percentage.
* Improved support for screen readers.

* Files unrelated to job could get removed by the `Cleanup List` logic.
* Prevent path traversal in orphaned job APIs.
* `Disk Full` errors from unrar were not handled gracefully during unpacking.
* Memory leak could occur during article decoding.
* In containers (like Docker), the Article Cache could exceed the memory limit.
* Diskspace checks would be too strict when unpacking to different disk.
* Prevent deadlock when a second signal arrives during shutdown procedure.
* Verification using SFV-checks could fail, even though files were correct.
* Don't log Warning during clean shutdowns.
* Windows: Uninstall would not remove Settings or Windows Service.
* Windows: Warn for OS-limit if more than 1024 connections are configured.
* macOS: AppleDouble files could result in failures in `Moving` stage.
* macOS: Restarting the application resulted in Terminal window.
* macOS: Included par2cmdline-turbo will now use all available CPU-features.
