We had to turn off strict mode (#4551) in Video.js due to a change in vtt.js. That has now been fixed in videojs/vtt.js#40 and released as part of 0.15.2 which will be available via #6333.
Fixesvideojs/vtt.js#15
Extend keyboard support for the SeekBar, and pass unhandled keydown events from components back to the player.
Switch from raw keycodes to the keycode module.
Using `userActions.hotkeys`, which can either be a function to match the hotkeys plugin, or an object with properties like `fullscreenKey`, see the documentation for more info.
This is currently off by default, we will consider turning it on by default in the future, see #5765.
Fixes#4048, fixes#3022.
Refactor of the clean task added docs/api, which didn't happen
previously. Re-order when things are generated to work around it.
Also, don't show rollup progress on netlify either.
Use npx babel-upgrade --write --install to initiate the upgrade. Then update grunt and rollup.
Decreases minified, gzipped filesize by about 1KB. Decreases build times by a few minutes.
This is upgrades rollup and uglify to latest versions. It also rewrites the rollup config to take advantage of the newest features of rollup. Minification is also split up into a separate process, mostly to speed up the build. The total build type can go down from about 2.5 minutes to around 1 minute for all the generated javascript files.
