I have posted 2.0.6 at sourceforge. Here are the improvements:

- Fixed crash with xyyxsievecl with overly large ranges for the GPU.
- More speed enhancements for xyyxsieve, mainly due to reduced memory requirements.
- Do not show ETA or percent done if less than 1% done and -P not used.
- Modify factor rate calculation to handle uneven factor distribution better.
- Fix srsieve2 to not check for algebraic factors when abs(c) != 1.
- Fix srsieve2 as it was counting factors of terms that had already been removed.

srsieve2 has some issues for (k*b^n+c)/d that are not fully worked out. The main ones are the removal of terms if d does not divide k*b^n+c and factors of (k*b^n+c)/d if gcd(d, p) > 1 and gcd(d, p) != p. I would appreciate if anyone could write some code to assist in those areas.
