PNaCl has been in development for a while, I'm having trouble understanding just what is being announced here. Is PNaCl now enabled by default in Chrome?
The news is that PNaCl has been enabled on the web in the latest release of chrome. Previously it shipped but ran only on the chrome web store and whitelisted sites like plus.google.com.
I think so. I just updated to Chrome 31 and it brought up a UAC in windows, which probably means that it was installing the PNaCl runtime since it usually doesn't require a UAC.
It was NaCL which was previously available. This one is Portable NaCL which presumably can run the code built from the same intermediate machine code on various platforms (ARM, x86/64, etc). The immediate winner here is which runs on ARM and x64.
Also pepper.js is a fairly recent thing, yes.
