Update CHANGELOG.md

Previously, using multiple track selection flags like `-S -A` would not work
as expected. The flags were treated as mutually exclusive, resulting in only
one type of track being downloaded.

This change refactors the track selection logic to properly handle combinations:

- Multiple "only" flags now work together (e.g., `-S -A` downloads both)
- Exclusion flags (`--no-*`) continue to work and override selections
- Default behavior (no flags) remains unchanged

+## decryption (str | dict)
+
+Choose what software to use to decrypt DRM-protected content throughout unshackle where needed.
+You may provide a single decryption method globally or a mapping of service tags to
+decryption methods.
+
+Options:
+
+- `shaka` (default) - Shaka Packager - <https://github.com/shaka-project/shaka-packager>
+- `mp4decrypt` - mp4decrypt from Bento4 - <https://github.com/axiomatic-systems/Bento4>
+
+Note that Shaka Packager is the traditional method and works with most services. mp4decrypt
+is an alternative that may work better with certain services that have specific encryption formats.

+```yaml
