Regex engine PCRE and PCRE2

[r0n]

Currently the regex engine information (PCRE) is sourced from (at least, I assume it is):
[1] https://www.pcre.org/original/doc/html/pcrepattern.html

Information about the newer engine (PCRE2) can be found here:
[2] https://www.pcre.org/current/doc/html/pcre2pattern.html

(It's almost like [2] is an copy of [1] with some things added)

There some differences, most if not all beyond my current use.
But I still need to provide some information about the regex regarding my projects. Currently I use the current (old?) page [1]  in my projects.

My questions:
1) Is the current QM version compatible with [2]
2) Will the next version of "QM" support [2]

QM2 uses [1].
QM3 will use [2].

Thanks!
