Shaka Player Upgrade Guide
If you are upgrading from v1 or v2, these releases are no longer supported, and upgrade guides are no longer maintained. You can use these old upgrades guides to upgrade in stages:
Since v3.0, Shaka Player has been following semantic versioning. (The IE11 deprecation announced before v3.0 happened in v3.1, which technically breaks semantic versioning guarantees. It is the only intentional exception.)
Upgrading from any v3 release to a newer v3 release should be backward compatible. The same is true of all major version numbers (v4 => v4, etc).
Here is a summary of breaking changes that might require upgrades to your application:
v3.1
-
New dependencies:
- TextDecoder/TextEncoder platform support or polyfill required (affects Xbox One, but not evergreen browsers); we suggest the polyfill https://github.com/anonyco/FastestSmallestTextEncoderDecoder Fallback included by default in v4.2
-
Support removed:
- IE11 support removed
v4.0
-

- Older TVs and set-top boxes that do not support MediaSource sequence mode can no longer play HLS content (since we now use sequence mode for that)
