[Qgis-developer] Questions about backwards compatibility and documentation

[icosa atropa]

I'm curious about the overall backwards compatibility plan looking
forwards.  Are things stabilizing?  I have a bunch of old work from
Ganymede that consitently crashes with the following message in the
terminal:

row number 0 is out of range 0..-1
Fatal: ASSERT failure in QList<T>::operator[]: "index out of range",
file /usr/include/qt4/QtCore/qlist.h, line 399

When I clicked though on the message box that comes up about reporting
issues to https://svn.qgis.org/trac/wiki, this page has a certificate
that expired a year ago and was generated for spatialserver.net.  So
confused!

Will this be less of a problem going forwards into 1.0?  Is there a
single file that's causing problems?  Is backwards and forwards
compatibility addressed within the documentation?  I didn't see this
*very* important issue mentioned in FAQ, ganymede (most recent) user,
etc.

Incidentally, I'm available for limited and
relatively-time-insensitive user guide proofreading and copy editing
over the next few weeks, if needed :)

best,
christian

Far better an approximate answer to the right question, which is often
vague, than the exact answer to the wrong question, which can always
be made precise -- j.w. tukey
