Adobe Flash Player 23 Beta Highlight
New and Updated Features: Extended Beta – Flash Player NPAPI for Linux
Linux users have access to both NPAPI and PPAPI versions of Flash Player. However, for the last four years, the NPAPI version has been held at 11.2 and regularly updated with only security fixes while the PPAPI version (used in Chrome and Chromium based browsers), is in line with the standard Windows and Mac releases.
In the past, we communicated that NPAPI Linux releases would stop in 2017. However, this is no longer the case, and once we have performed sufficient testing and received community feedback, we will release both NPAPI and PPAPI Linux with their major version numbers in sync and on a regular basis.
Because this change is primarily a security initiative, some features (like GPU 3D acceleration and premium video DRM) will not be fully implemented.
If you require this functionality, we recommend that you use the PPAPI version of Flash Player
