apparently you mis-read what i wrote, and/or mis-remember all the
prior threads on this subject. we are specifically going to have
backwards compatibility, with SANE 1.1.0 only adding some additional
frame types, and perhaps clarifying some more well-known options. We
are doing exactly what you wish, so I do not understand your

i agree with this idea- but it has no real bearing on our release
cycle, since sanei is not part of the public API. in fact, i have a
sanei_gamma on my hard-drive right now :)

your understanding of linux kernel and mine do not jive, as i
routinely see old unmaintained hardware drivers dropped. i have
several ancient scsi and ethernet cards which have not worked since
2.0/2.2. If you want those old drivers to be forward ported to API
changes, then either we have to do it, or we have to get more
developers. I am hoping for the latter :)
but your desire to keep older hardware working does not seem to jive
with the current state of the Avison bug reports...

yes- i agree. i will gladly hand over the release coordination to you :)

which i believe are worth quite a bit more than my 2$cents :)
