A rough changelog of the major versions. For a more complete changelog, see:


These versions were created by @tjhrulz.
WebNowPlaying is a drop-in replacement for Rainmeter's NowPlaying plugin, the browser extension would connect to the plugin and let Rainmeter read/control browser media.
It also allowed for additonl controls, such as the players volume.


Versions from here on were created by @keifufu.
The extension could now connect to multiple adapters.


Support for Desktop Players was added, read more about it here.
Adapters can now also read what functionality the current media supports, e.g., canSkipNext, canSetRating, etc.


Adapters can read and send events to all/any player(s) instead of just the active one.
Events return whether they succeeded or failed.
Players report their available repeat modes.
Shuffle and repeat modes can now be set instead of just toggled.
