• Replaced APOLAR->glen and APOLAR->dime keywords with APOLAR->grid
• Deprecated mergedx. Added mergedx2
• mergedx2 takes the bounding box that a user wishes to calculate a map for, as well as a resolution of the output map. An output map meeting those specifications is calculated and store.
• Added pKa tutorial
• Added warning about strange grid settings (MGparm)
• Fixed a bug in vpmg.c that occured when a user supplied a dielectric map with the ionic strength set to zero, causing the map to not be used.
• Removed deprecated (as of 0.5.0) tools/manip/acc in lieu of new APOLAR APBS features
• Added enumerations for return codes, new PBE solver (SMPBE) and linear/ nonlinear types
• Added in code for Size-Modified PBE (SMPBE)

Bug fixes and API changes

• Fixed buffer over-run problem
• Fixed case inconsistency with inputgen.py and psize.py scripts which caused problems with some versions of Python
• Fixed bug wherein 'bcfl sdh' behaved essentially like 'bcfl zero'.  Now we have the correct behavior:  'bcfl sdh' behaves like 'bcfl mdh' thanks to the multipole code added by Mike Schnieders.  Interestingly, this bug didn't have a major on the large-molecule test cases/examples provided by APBS but did affect the small molecule solvation energies.  Thanks to Bradley Scott Perrin for reporting this bug.
• Added support for chain IDs in noinput.py
• Fixed bug in noinput.py where REMARK lines would cause the script to fail.
