Release Date: December 3, 2014.

• mmCIF
  • fast loading
  • multi-letter chain support
  • loads auth_asym_id as chain and label_asym_id as segi
  • fetch with “fetch 1a00, type=cif”
  • saving (.cif extension, atoms and symmetry only)
  • experimental connect_mode=4 uses components.cif for bonding (file must exist in current directory or COMPONENTS_CIF environment variable)

• pdb loading: ignore SCALEn in suspicious cases
• load Desmond idx files
• load spi (spider) maps
• load map and mrc extensions as ccp4
• Python callback objects now stored in PSE files

• improve cartoon and CGO transparency by triangle sorting
• color CGOs by ramp

• gray out missing atoms/residues in seq viewer. Missing residues are read from mmCIF _pdbx_unobs_or_zero_occ_residues records

• Right-Mouse-Button zoom doesn't depend on clipping planes anymore

• added --help and --version command line arguments

• fixed full screen for OS X 10.7+
• fixed broken Quicktime export

• MacPyMOL now available with and without bundled Python. The MacPyMOL-v1.7.4.x-syspython.dmg installer uses the system Python (/usr/bin/python2.7) and allows for better integration with scripts that require additional Python modules. We also provide pymol-v1.7.4.x-Darwin-x86_64.tar.gz which uses system Python and the X11 (XQuartz) OpenGL layer.

• deprecated full_screen setting in favour of the full_screen command and to handle external full screen control by the window manager

• Import Phase pharmacophores with Maestro's “View in PyMOL” feature

• cmd.set_state_order (new)
• cmd.load_coords (changed, works on selections now)
• cmd.load_coordset (was: load_coords)
• cmd.get_coords (new)
• cmd.get_coordset (new)
• cmd.get_volume_field now returns numpy array

• fetch: load PDB from memory if fetch_path not writable
• line_width < 1

• Shipped libraries
  • OS X 10.9+, MacPyMOL with bundled Python: scipy.linalg broken. Workaround: Use MacPyMOL-v1.7.4.x-syspython.dmg or pymol-v1.7.4.x-Darwin-x86_64.tar.gz, those use the system Python.
  • OS X 10.7: APBS binary broken. Workaround: Install apbs from fink (or macports, etc.), and in the “PyMOL APBS Tools” panel, point the “APBS binary location” for example to /sw/bin/apbs

• Fixed transparent cartoon cylinders
• Fixed multi-object CIF export
• Enable CIF loading in JyMOL
• pickle protocol 1 for session_compression

• Fixed stereo background color bug
• Fixed logging settings from the Tcl/Tk menus
• Fixed picking when cartoon_debug is set

• Fixed walleye and crosseye stereo (regression of v1.7.4.2)

• fix cartoon_ring_mode ring center color
• fix “Zalman” stereo
• fix “custom” selection operator
• fix crash with “copy” command on transformed objects
