New features for versions 1.10-2.00 of SOLVE

Resolve version 2.00 (Reciprocal-space solvent flattening and maximum likelihood density modification) is now available for SOLVE users!
SOLVE now has easy scripts for SAD phasing.
SOLVE has even better MAD phasing! SOLVE now re-refines scattering factors using the final heavy atom parameters, improving the final phases. In combination with version 1.04 or later of resolve, the final maps are greatly improved over version 1.17.
Must faster search for solutions: SOLVE now follows only the very best solution by default, greatly speeding up the search in most cases.
You can start from MR or other input phases.
You can read CCP4 unmerged intensities directly.
You can specify a SOLVETMPDIR where SOLVE will write scratch files.
You can tell SOLVE where some sites are and go on from there easily with ANALYZE_SOLVE and with ADDSOLVE
There is now a SOLVE FAQS page.

SOLVE versions starting with 1.16 fix a serious bug that was present in versions 1.10 to 1.15. This bug was that upon conversion from SOLVE's asymmetric unit to the CCP4 asymmetric unit (done in routine "SOLVE" for all data, whether mtz input or not) the phase of FA relative to Fp was not swapped when the asymmetric unit changed. This affects the difference Fouriers calculated by SOLVE for space groups where the CCP4 and SOLVE asymmetric units for reflections are not the same.
SOLVE version 1.17 fixes some array dimensioning errors in versions up to 1.16 that can cause it to hang when finding very large numbers (50 or so) sites.
Solve version 1.17 sets the default of "resolution_steps" to 1 (it was 3 in previous versions). This improves MIR results for polar space groups but could slow down Solve in some cases.
Solve version 1.18 had a minor bug in the way it dealt with SAD phasing, always substituting in the default f-doubleprime values for the heavy atoms from the tables, and including non-zero atomic scattering factors. Version 1.19 allows the user to input f-doubleprime (with fprprv_mad) and sets the form factors other than f-doubleprime to zero. This creates the appropriate scattering factors for a pseudo-derivative that is just like a native but has anomalous differences. This pseudo-derivative is used for phasing with the observed anomalous differences.
Solve version 1.18 had a dimension error preventing the use of more than 5 derivatives; this is fixed in 1.19.
Solve version 2.00 fixes a bug in previous versions of combine_all_data where the number of wavelengths was not read in correctly for the second dataset.
Solve version 2.00 has scattering factors for Br
Solve version 2.00 fixes bug which prevented solving SAD datasets in space group P1.
Solve version 2.00 restores compatibility with new d*trek format.
