Does anyone know if the 32-bit of pepper flash plugin support has ended? I use chromium btw.
No, it didn't end in March 2016, and it hasn't ended yet in March 2017
Adobe's Flash Player Tech specs / System requirements doesn't say anything about only 64-bit Linux (actually only supports 32-bit WinXP & Vista)
The Download page (for "another computer" to pick the version) still lists 32-bit Linux (the Win & Mac versions only differentiate between NPAPI & PPAPI, no mention of 32 or 64-bits...)
- The About Flash Player page seems to have a new version for Firefox on Linux (NPAPI), previously it was frozen around version 10.x and appeared to have had it's support dropped, but now it's back at the same version as every other OS (version 24.x today)
