Improvements, deprecations

August 24th, 2015: Structure Checker 15.8.24

Improvements

August 3rd, 2015: Structure Checker 15.8.3

API changes

July 6th, 2015: Structure Checker 15.7.6

Bugfixes

  • Wedge Error Checker  didn't detect non-stereo wiggly bonds.

Improvements

  • Clean Wedge Fixer converts non-stereo wiggly bonds to single bonds.

June 22th, 2015: Structure Checker 15.6.22

Bugfixes

  • Solvent Checker  threw exception if input molecule couldn't be converted to SMILES format.

April 13th, 2015: Structure Checker 15.4.13

New features

January 26th, 2015: Structure Checker 15.1.26

Bugfixes

  • Wedge Error Checker didn't always agree with Wedge Clean Fixer. From now on the molecules fixed by Wedge Clean Fixer are accepted as correct by Wedge Error Checker.

January 12th, 2015: Structure Checker 15.1.12

Improvements

  • Aromaticity error fixing improvements: Dearomatize and Rearomatize fixers can fix aromaticity errors in heteroaromatic rings (containing only carbons and nitrogens) in unambiguous cases.

Bugfixes

  • Bond Angle Checker did not accept some bond angles as correct. Bonds connected to a ring were affected.

January 5th, 2015: Structure Checker 15.1.5

Bugfixes

  • From now on Rare Element Checker will not detect deuterium (D) and tritium (T) as rare element.

November 17th, 2014: Structure Checker 14.11.17
