 * Added Mango OS mode from DX220.
 
 **Note 1**: Mango OS player was taken from DX220, and, as such, is not 100% compatible. The known restrictions and problems are:
-* Only first 4 Digital Filter options actually work.
+* Only first 5 Digital Filter options actually work.
 * Only two levels of gain actually work: Medium and High produce the same result.
 * Optical Output setting does not work.
 * Due to the new touch screen driver, on DX160 2020 edition, Mango OS boots much longer than on 2019 edition.
-* ~~If you put on Pause during PCM playback for more than a minute, resuming playback produces silence. Workaround: push Pause/Play one more time.~~ (resolved in 1.26b3)
-* ~~After playing DSD files, PCM files don't produce sound. Workaround: either turn the device off then on, or put on pause for one minute or more and resume playback.~~ (resolved in 1.26b3)
 
 **Note 2**: MagiskManager icon is, actually, a stub injected by Magisk core. It is intended by the developer to help installing full MagiskManager, but I disable it to stop annoying. Should you need [MagiskManager, please install it manually](https://github.com/topjohnwu/Magisk/releases).
