JFFS2: Releases? Versions?

[Bernhard Priewasser]

Hi all,

i have just a simple question about JFFS2 & versioning. Too simple 
perhaps... please be patient with me...

I'm confused about the version numbers of JFFS2, "JFFS2 version 2.2. 
(NAND)" (out of a dmesg / boot) for example.

If source code + CVS available: How can i determine the release version?
If source code available: How can i determine the release version?
How can i determine the release of JFFS2 currently running in a kernel?
Is there some changelog "overview" (not only for single files)?

I have to start evaluating (or rather analyzing...) JFFS2 on different 
platforms and flash chips, and it's hard to distinguish between the 
releases already running on some devices here.

Best Thanks & Regards,
Bernhard
