CrystalMaker 7.2.4

Released: 28 August 2007

1. Workaround for System Graphics Export Bug. We have introduced a workaround in our graphics export code, which appears to cure a system-related problem with "missing atoms" in high-resolution TIFF, PNG or PSD files, under Mac OS X 10.3 "Panther" or earlier.
   
   This problem is not seen on Mac OS X 10.4 "Tiger". It also does not affect high-resolution JPEG, SGI, BMP, PICT, TGA or JP2 file export.
   
   
2. Toughened File Import Code. We have made our ICSD and PDB file import more robust, to guard against rogue file formatting problems.
   
   
3. Miscellaneous Changes. A minor issue with saving grid and ruler units when editing a crystal, has now been resolved. Vacant crystal sites are now correctly saved in binary files.

CrystalMaker 7.2.3

Released: 30 April 2007

1. Extended PDB file import. Site occupancies are now read from the PDB file, making it easier to evaluate disordered structures.
   
   
2. Resolved a potential problem with polyhedra generation for disordered structures. The problem was triggered by highly-disordered structures in which virtually co-incident atoms of the same type were defined. Although rare in most cases, some macro-molecular structure refinements were found to contain such issues.
   
   
3. The Define Cluster command now works correctly on Intel systems, as well as PowerPC.
   
   
4. Other Changes. Custom bond styles can now be reliably set for multiply-selected bonds. Surface plots can now be applied to multiple windows, via the Window > Synchronize command. Windows opened via the Files pane of the Overview window now "remember" their source files.

CrystalMaker 7.2.2

Released: 8 March 2007

1. New User's Guide. The full-feature version of CrystalMaker is now shipped with a new, 6th Edition of the CrystalMaker User's Guide. The new edition features many new diagrams and numerous changes to the text. The layout is now much clearer and easier to read on screen, as well as in print.
   
   We have also updated the Demo User's Guide, and this is now available from the Help menu when running CrystalMaker Demo.
   
   
2. Easier Stereo-Pair Viewing. When switching between standard plots and stereo-pair plots, annotation and axes are automatically rescaled, to preserve the original view. Textbox selection frames and other graphics elements now work consistently between different viewing modes.
   
   
3. More Rigorous Auto-Bonding for Crystals. A rare issue with certain bonds not being generated by the automatic bonding command (e.g., Transform > Generate Bonds Now) has been resolved. The problem occurred for crystal structures which contained varying bond lengths for a particular element pair combination, and where the longer bonds also straddled the unit cell boundary.
   
   
4. Other Changes. This version includes a number of other improvements:-
   
   
   • Improved recognition of dual-origin spacegroups, through the provision of more spacegroup synonyms (e.g., "F d 3 m" as well as "F d -3 m".
   • An issue with Universal File Types for CrystalMaker CMDF and CMD5 file types has now been resolved.
   • Grids are no longer automatically displayed following the Edit > Structure command.
   • Switching between Colour and Black & White modes preserves the surface type.
   • The program no longer hangs when attempting to load CrystalMaker-6 files that contain invalid bond or polyhedral definitions.

CrystalMaker 7.2.1

Released: 18 January 2007

1. Formula and Density Calculations. A new menu command (Transform > Calculate Formula & Density) allows you to display the calculated formula for any displayed structure. If the structure is a crystal, the calculated density is also shown, printed in the Output window.
   
   
2. Automatic Removal of Duplicate Crystal Sites. Some input files - most especially those in the CIF format - mistakenly list the entire contents of the unit cell, instead of just the asymmetric unit. This does not stop CrystalMaker from plotting the structure, but symmetry operations result in superimposed atoms which can cause errors in the polyhedral face generation.
   
   Given that a number of incorrectly-specified CIF files are now in circulation (e.g., via the Cambridge Structures Database), CrystalMaker now has to take special precautions when reading what is purported to be the "asymmetric unit" of a crystal. Symmetry operations are now used at an earlier stage, to purge redundant sites.
   
   
3. More Informative Atom Info Icons. The icons are now adapted to take into account stick and polyhedral plot types, where atoms may not be plotted as spheres (but as ball joints, for example), and may appear use a different colour (e.g., the bond colour).
   
   
4. Other Changes. This version includes a number of other improvements:-
   
   
   • A cosmetic issue with the Overview Window's scrollbar has now been addressed.
   • Information about default bond styles is now saved directly in a CrystalMaker binary file, so that some rare cases of custom-created bonds can be displayed correctly.
   • Chemical formulae are now correctly presented for SHELX files immediately after the file has been loaded. SHELX files have unusual site occupancy/multiplicity codings, requiring special action at the input stage.
   • Fixed a potential problem with the Tile Windows command. With a very-large number of windows open, the resulting tiled windows could be too small to display both the notebook text and crystal graphics. In these cases the notebook pane is now hidden.

CrystalMaker 7.2.0

Released: 4 December 2006

1. Non-Destructive Bond Editing. Major improvements have been made to the Edit > Bonding command, for crystal structures. Previous versions of the program regenerated the crystal structure, resulting in the loss of custom atom colouring, labelling or selections. Now, the existing structure is retained, allowing users to freely experiment with different bond settings.
   
   
2. More Flexible Polyhedral Model Options. The Polyhedral model type now allows more flexibility in the combination of model elements used. "Stick" and "ball-and-stick" styles can now be combined, with the program generating atom spheres or "ball-joint" atoms as required.
   
   
3. User-Friendly CrystalMaker Text Export. CrystalMaker Text files are now exported using special comments lines to explain the file syntax. Other improvements include the explicit listing of all general equivalent positions, and the removal of duplicate atom definitions from the TYPE card.
   
   
4. Intuitive Atom Info Window Editing. In order to make the program more intuitive we have changed the behaviour of the Atom Info Window slightly. Changing the radius or colour value for an element row will now update all sites with the same element symbol - rather than just those sites which currently match the element symbol's colour/radius/atom style settings.
   
   For greater convenience, the Options popup menu can now be displayed by control-clicking in the Atom Info window.
   
   
5. Revised Window Tile & Stack Commands. The Window > Stack command now preserves the existing window front-to-back ordering. The Tile command ensures that the window's z-ordering is reflected in the tiling arrangement, such that the bottom-most window appears at the top left-hand side of the screen, with upper windows being arranged in sequence to the right and below.
   
   
6. Other Changes. This version includes a number of performance enhancements and bug fixes:-
   
   
   • Stick bonds are now more accurately rendered, for both "Polyhedral" and "Stick" model types. Stick bond radii are sized relative to the smallest sphere in a structure, whether this be visible or not. Users can control the relative bond radius using the Bonds pane of the Model Options window.
   • The Output Window is no longer listed with other Graphics windows at the bottom of the Window menu. Instead, users can display the Output Window using the Window > Palettes submenu.
   • A possible issue with the Optimize Range commands has been resolved. Structures which contain a mix of isolated molecular units and fully-interconnected units (sheets, chains or a framework) were being processed as if they were molecular crystals, resulting in an empty unit cell.
   • A very-rare case with oversize thermal ellipsoids has now been fixed. This problem only affected structures where thermal ellipsoids were larger than the unit cell dimensions.
   • A problem in which large, undefined thermal ellipsoids could be created via the Make Polyhedron command, has now been resolved. This command now generates a dummy, isotropic thermal ellipsoid for a newly-created centroid atom. The centroid atom uses a default setting for U_iso; to change this setting, you can export the structure to a CrystalMaker text file then add a UISO tag for the dummy site to specify a different size.
   • MacMolecule text file output now correctly lists the first atom type in a structure.
   • An "error -50" problem that appeared when trying to load certain binary files, has now been resolved. The problem occurred when trying to load a file with formatted notebook text, into a window which had a closed Notes Pane.

CrystalMaker 7.1.7

Released: 2 October 2006

1. Thermal Ellipsoids Resized. A problem with thermal ellipsoids being plotted too small has now been resolved. Earlier versions of the program incorrectly took the square root of the probability factor, resulting in ellipsoids that were approximately 20% too small. This version plots the ellipsoids at the full sizes and will automatically re-generate ellipsoids loaded from earlier files. We sincerely apologize for any inconvenience caused; please contact us directly if you require further details.


2. Improved Ellipsoid Generation. Numerous improvements have been made to other aspects of thermal ellipsoid plotting, with much faster and more reliable calculation of ellipsoid axes and the boundary ellipse plus improved label positionning.
   
   
3. Thermal Ellipsoid Error Checking & Recovery. Even a cursory inspection of published structure reports yields many instances of unplottable temperature factors - presumably not just typographic errors, but the result of automated refinement methods? In the light of this, we have introduced robust error detection and recovery. Ellipsoids with invalid Uij or Bij tensors are now replaced by isotropic temperature factors, with warning messages, listing the offending sites, printed in the Output Window.


4. Label Scaling for Exported Graphics. Previous versions of CrystalMaker used a contant font size for atom labels, regardless of the output size used in exported graphics. Labels are now scaled automatically, so that the exported graphic more-closely resembles the on-screen display.


5. Other Changes. This version includes a number of performance enhancements and bug fixes:-
   
   
   • Chem3D files can now be loaded without bonds being generated. The "Generate Bonds at File Import" menu option is respected for this file type.
   • A very-rare problem with reading from files with an excessive number of different atom types (more than 32 element types) has now been resolved.
   • An initialization issue, which could lead to a crash when displaying the Edit Elements window, has now been fixed.
   • Leaving the Labels pane of the Model Options window when exporting graphics, now longer results in the screen display being rescaled.
   • Help buttons in dialogs and windows have been updated to ensure that they now display the correct help pages.
   • A rare problem (introduced in version 7.1.6) that resulted in some lone spheres not being rendered for polyhedral plots, has now been corrected.

CrystalMaker 7.1.6

Released: 7 September 2006

1. Support for ICSD Spacegroups. CrystalMaker now recognizes the abbreviated spacegroup syntax, as used by some files in the ICSD database. This (non-standard) syntax omits spaces and can include the origin choice as part of the spacegroup symbol (e.g., a trailing "S" or "Z"). CrystalMaker now decodes the syntax and applies the appropriate symmetry operators.


2. Optional Auto-Generation of Bonds. When loading a text file from a non-CrystalMaker file format (e.g., CIF, PDB, SHELX), CrystalMaker will by default attempt to generate bonds. For some structures this can be slow - especially if there is an excessive number of atoms or if the appropriate element table has not been set.
   
   You can now instruct CrystalMaker to suppress this automatic bond generation e.g., so that you can quickly display a large structure, or manually define bonds with the Edit Bonding command. Use the Generate Bonds at File Import command on the Transform menu to turn auto bond generation on or off.


3. Improved File Format Checking. CrystalMaker uses the operating system to identify different file types, but occasionally this method breaks down and users are left with apparently "blank" document icons. This can happen if files are transferred from another operating system without the correct file extensions having been applied. CrystalMaker can now look inside such files and auto-detect whether or not they can be opened.


4. Miscellaneous Changes. This version includes a number of new features plus various bug fixes and workarounds for changing system behaviour:-
   
   
   • The "Auto-Generate Bonds" command on the Transform menu has been renamed as "Generate Bonds Now". A sheet alert is now displayed by this command, informing users about the nature of this operation. The sheet can be suppressed in future operations, by selecting the "Don't Show This Again" checkbox.
   • Vertex atoms are now plotted at their ball-and-stick sizes, making it easier to combine "ball-and-stick" and "solid polyhedral" model elements in the same plot.
   • The Edit Elements window has been given a slimmed-down look.
   • Polyhedral "stick" plots now show smoothed "ball" joints.
   • A potential problem with saving files on Intel-based Macs has now been resolved. The issue only affected files with blank notebook panes, and involved an issue with the system function for converting text to the Rich Text Format (RTF).
   • The Symmetry Options dialog now correctly reports origin choice settings back to the Edit Crystal sheet.

CrystalMaker 7.1.5

Released: 26 July 2006

1. Improved Polyhedral Generation. The program is now more tolerant of out-of-plane atoms when generating large polyhedra. This results in less likelihood of individual faces being subdivided into smaller planes - and also resolves a potential problem with some faces not being plotted because of face distortions.


2. Revised Make Polyhedron Command. The Selection > Make Polyhedron command has been revised so that the "symmetrically-equivalent bonds" option works more effectively. In earlier versions of the program this option resulted in only bonds parallel to existing ones being generated.


3. Fixed a Notebook Issue with Intel Systems. A problem with setting the focus for Notebook text has now been resolved. This problem also caused an "Error -50" alert to be displayed on Intel systems.
   
   Users should be aware that problems with the underlying system text editor technology and earlier versions of CrystalMaker could cause Notebook text to be duplicated. We advise users to check review the contents of the Notebook pane when they next load a file, and to delete any duplicate text, as required.


4. More Reliable Unit Cell Labelling. In some very unusual instances, the unit cell labels (0, A, B, C) became interchanged as a structure was rotated. This has now been fixed.


5. Miscellaneous Changes. A rare case where the program could crash during file import, following a "duplicate atom" alert, has now been resolved. Other changes include support for formatted notebook text in CrystalMaker-for-Windows binary files, plus updated contact details in the online help and other documentation.

CrystalMaker 7.1.4

Released: 26 June 2006

1. Chemical Formula Calculation. CrystalMaker now generates the chemical formula, based on site occupancies and multiplicities. The formula is displayed in the Output Window, when a new structure is loaded or an existing structure is recalculated. The formula can also be displayed (together with the calculated density) in a Bond Data file (File > Export > Bond Data).


2. Improvements to the Notebook Pane. Extensive improvements have been made to the Notebook pane of the Graphics window, resulting in smooth, flicker-free resizing and updating. Control-clicking in the pane now sets the focus correctly and users can set default text options even when no structure is being displayed. A problem with the display of notebook text on Intel-based Macs has also been fixed.


3. Improved Slice Model Command. Executing the Slice Model command in Polyhedral Mode now ensures that all atoms on one side of the plane remain hidden, even if the model type is changed.


4. Miscellaneous Changes. Specifying an Origin Choice using the Edit Crystal sheet now works correctly. The CrystalMaker Cache is now more thoroughly purged at startup and quitting times. The size of the Demo version has been reduced slightly.

CrystalMaker 7.1.3

Released: 29 May 2006

1. Extended Symmetry Handling. Previous versions of CrystalMaker used one set of symmetry generators (general equivalent positions) per spacegroup, with multiple origin settings handled via origin offsets. Starting with version 7.1.3, different sets of symmetry generators are available for the different origin choices, and origin offsets are no longer strictly required.
   
   Users can choose a particular spacegroup origin setting by using the Symmetry Browser. Alternatively, power users can enter the origin choice directly in the Edit Crystal sheet's Spacegroup field, by adding the text "[origin 1]" or "[origin 2]" after the spacegroup name, e.g.,
   
   I 41/a m d [origin 1]
   
   This change fixes a possible bug with incorrect symmetry generators saved in a CIF file, when origin choice 1 was specified for one of the 24 dual-origin spacegroups (e.g., I 4₁/amd).


2. More Powerful SHELX File Import. SHELX "site occupancy factors" are now decoded to give conventional site occupancy values in the range 0 to 1. As part of this process, the program now checks for redundant symmetry operators and warns the user if any are detected.
   
   We note that SHELX files use a slightly unusual method of expressing site occupancies, in which the conventional occupancy data are combined with site multiplicities and constraint flags, to give a single "factor" value which can be greater than 20 in some cases.


3. Improved Video Recording Feature. You can now initiate a video recording in "linear video" mode without having to open a structure first. This is useful when the movie is to contain a series of structures from a single text file (e.g., a multi-structure CIF or PDB file), or if you want to open a large number of structures into an existing window, without having to open a "dummy" file first.


4. Multi-Structure PDB Files and Video Recording. The Protein Data Bank file specification version 2.1 allows for multiple structures to be saved in the same text file, with the use of "MODEL" and "ENDMDL" data tags. CrystalMaker can now read from these files - the individual structures are plotted in separate windows.
   
   You can also now record a movie, with the multiple structures displayed in separate frames. To do this:
   
   
   1. Close any existing graphics windows.
   2. Display the Video Recorder palette (Window > Palettes > Video Recorder).
   3. Click the Record button and specify a name and location for your movie file to be saved.
   4. Open your multi-structure PDB file using the File > Open command.
   5. Click the Video Recorder's Stop button to save the movie.


5. Improved Auto-scale Mode. The global "auto-scaling" feature has been replaced by a structure-specific method. Different windows can have auto-scaling enabled or disabled, and switching between them preserves their states.
   
   A separate, but long-standing issue with auto-scaling has also been fixed. If a structure has just been loaded into the program, and the range is changed or the auto-scale button pressed, the model would shrink to a smaller size, before being reset to the correct size. This issue, related to changing unit cell offsets, has now been resolved.


6. Miscellaneous Bug Fixes.
   • A problem with Overview Window thumbnail titles being reset has now been fixed. This problem occurred when the "Open in New Window" button was set and a Recent File thumbnail was clicked.
   
   
   • A problem with colour bond drawing in "Black-and-White" mode has now been resolved.
   
   
   • The ruler visibility state is now correctly saved in the preferences file.
   
   
   • Multiple copies of notebook text are no longer inserted into hidden notebook fields.

CrystalMaker 7.1.2

Released: 22 March 2006

1. Faster bond diagnostics displayed in the Edit Bonding sheet. Coordination displays for both "from" and "to" atom types are calculated using a faster algorithm.


2. New Licence Agreement Dialog. A new dialog appears when the program is first launched, or when installing an update. Users must agree to the terms of our standard licence agreement before then can proceed with software installation.


3. More Rigorous Cluster Generation. The Generate Cluster command now works correctly for the case where target atoms are located at the origin in a crystal with highly-oblique cell angles. An issue where incorrect coordination numbers could be reported for such sites (e.g., in the Atom Info window) has also been resolved.


4. Other Changes:
   
   
   • When importing sites from a Chem3D Cartesian file, the atoms are now numbered from one instead of zero.
   
   
   • SHELX files containing mixed-case element symbols can now be interpreted correctly.
   
   
   • Fixed an issue with thermal ellipsoid generation, for certain structures where negative values had been used for fractional coordinates.
   
   
   • Changing the plot range in "auto-scale" mode now causes the scale to be recalculated correctly.
   
   
   • Splash screen displays correctly on Mac OS X 10.2 "Jaguar".
   
   

CrystalMaker 7.1.1

Released: 15 February 2006

1. New Online Help System. The online help has been completed updated, using a new display style, improved keywords and indexing, and new help topics.


2. Other Changes. This version contains a number of interface improvements, plus various minor changes, designed to improve some areas of file import/export.
   
   
   • Many of the windows have been subtly improved, using the new "Compositing Mode" for improved drawing.
   
   
   • CIF files with missing coordinate values (designated by a "." in place of a number) can now be loaded.
   
   
   • Fixed a possible crash on some systems, when using the Export Web Page command. The program version is now written to the output file.
   
   
   • Fixed an issue reading CrystalMaker binary files generated by version 7.1 containing unicode textboxes.

CrystalMaker 7.1.0

Released: 6 February 2006

1. Universal Binary. CrystalMaker 7.1 has been compiled as a single, "Universal Binary" application. This runs natively on both PowerPC- and Intel-based Macs. The program's underlying "engine" has been extensively updated and tuned to provide seamless compatibility between the two platforms - allowing the sharing of input and output files, including graphics, binary data files and preferences files.
   
   
2. Depth Profiling. This new feature allows you to easily visualize the interior of a bulk material. You can profile the material's structure, by controlling the vertical extent of material to be shown at any time. Atoms "in front" of the slab can be hidden completely, or made translucent; atoms beneath the slab can be faded into the background.
   
   The new Depth tab of the Rendering Options window lets you construct a "depth profile" by clicking-and-dragging control handles. You can also choose from one of a number of preset "depth profiles". A depth slider control lets you "zoom" through varying depths of material, interactively.
   
   
3. Multiple Graphics Formats for High-Resolution Output. A new Export > Pixel Graphics command lets you export high-resolution graphics in a wide range of image formats, including JPEG, TIFF, PNG, SGI, BMP and PICT (previous versions of CrystalMaker provided high-resolution output only in PICT format).
   
   A separate Export > Vector Graphics command, is provided for saving vector graphics in the native Apple PICT file format.
   
   
4. Auto Update Checking. If you are connected to the internet, you can now check for program updates without leaving CrystalMaker, thanks to a new Check for Update command on the Help menu. There is also the option of automatic update checking, at regular intervals.
   
   
5. High-Quality Bond Rendering. Bond cylinders can now rendered using Quartz graphics, for smooth, high-quality screen display.
   
   
6. Other Changes. A large number of "under the hood" changes have been made, adopting new system technologies and bringing the program fully up-to-date to ensure that you get the best-possible user experience on new and future Mac systems. Various new features and bug fixes have also been rolled into this release, including:
   
   
   • Faster display and manipulation of red/blue stereo plots.
   
   
   • Overview window thumbnail files now require much less disc space. The files are now saved as space-efficient JPEG files, rather than PICT files.
   
   
   • The notebook pane is now correctly redrawn after the application has been hidden.
   
   
   • Fixed a very-rare issue with the calculation of coordination numbers for sites in structures with very-oblique axes.
   
   
   • Various compatibility issues with old-format binary files have now been resolved.
   
   
   • The keyboard shortcut for the Rotate Selection command, "O", now toggles between the two rotation modes, "Rotate All" and "Rotate Selection".
   
   
   • Improved handling of PDB-format text files. Two-character element symbols are now correctly interpreted. Atoms are now labelled using their unique atom serial numbers, rather than their residue symbols.
   
   
   • Please note that thermal ellipsoids are no longer retained when converting from 'crystal' to 'molecule' mode. We recommend that you work in 'crystal' mode wherever possible, in order to preserve the underlying crystallographic basis.
   
   

CrystalMaker 7.0.4

Released: 17 October 2005

1. Interface improvements. The "Reset Palette Locations" command has been renamed "Reset Palettes" and moved from a submenu, to the Transform menu. Various other menu titles have been shortened.
   
   
2. Extended Place Molecule command. The scope of the Place Molecule command has been extended, to allow structures with thermal ellipsoid data to be placed. Furthermore, default (isotropic) thermal ellipsoid parameters can be applied to placed structures that do not have existing thermal ellipsoid data.
   
   
3. Miscellaneous bug fixes. Atoms with thermal ellipsoid parameters can now be safely duplicated. Rotation of structures with custom-defined atom styles or colours now works correctly in Thermal Ellipsoid mode. Fixed a rare problem with the Torsion Angle tool; if a colinear group of atoms had been clicked, the tool would not allow subsequent measurements.

CrystalMaker 7.0.3

Released: 8 September 2005

1. New element table for organic structures. The new "CSD CrystalMaker Covalent Radii" table provides improved bond search results when working with organic or organo-metallic structures. Atomic radii are based on Cambridge Structures Database (CSD) data, but modified to work with CrystalMaker's bond search algorithms.
   
   The "CSD CrystalMaker Covalent Radii" element table is now our recommended dataset for use with organic structures.
   
   
2. Edit bond specifications interactively. Existing bond specifications can now be modified using the Add/Delete Bond Tool. If an existing bond specification includes atom types A and B, shift-clicking with the Add/Delete Bond Tool had no effect. In the new version, the existing A-B bond specification is modified to ensure that the two clicked atoms will be encompassed by the bond specification (i.e., the maximum bond distance is increased, if needed).
   
   
3. Improved Optimize Range commands. The Hide/Repair Molecular Fragments and Show Molecular Cell commands now work for structures which have atoms hidden by site. In previous versions of the program, optimizing the range for a structure with hidden sites could result in all sites being hidden.
   
   
4. Less obtrusive partial-bonding warning. The "not all bonds could be found" error alert has been replaced by a warning printed in the Output Window. This should make it easier to load multiple text files - and prevent disruption to movie recording.
   
   
5. Save function enabled for element tables. Element Tables chosen via the Edit Elements window, and saved using that window's Save button, are now correctly loaded at startup time.
   
   
6. Improved rendering of stick plots. The "two-tone" bond style is now correctly rendered, using appropriately-coloured joints.
   
   
7. Fixed a possible crash with bond distance tool on Japanese systems. The bond distance and bond angle tools now function correctly on a Japanese system, displaying Ångstrom and degree symbols, respectively. A font mismatch problem involving the Ångstrom symbol - which could cause a crash - has now been resolved.
   
   
8. Minor bug fixes. Attempting to edit the default polyhedral style (Atoms pane of the Model Options window) could result in unrecognized model styles (generic document icons displayed in the Atoms list). This has now been fixed.
   
   Reading and writing user preferences to file has been made more robust. Bond colours saved in CrystalMaker Text files are now recognized. The "Open in New Window" command now correctly activates the frontmost window.
   
   When rotating a crystal structure on screen, traces of the unit cell outline could be left unerased; this problem has now been eliminated.

CrystalMaker 7.0.2

Released: 16 August 2005

1. Support for new CIF dictionary. Various new tags, introduced in version 2.3.1 of the CIF Dictionary (June 2005) are now supported. These include: _space_group_name_h-m_alt, _space_group_it_number and _space_group_symop_operation_xyz.
   
   
2. Improved behaviour of the Copy Graphics sheet. The Copy/Export Graphics sheets now scale the pixel dimensions by the output resolution, so that high-resolution output is easier to generate.
   
   By default, the output size (measured in cm or inches) is the same as the screen size, but the resolution is higher. So for example, if the screen display was at 800 x 600 pixels (and the screen resolution is 72 dpi), then, an output resolution of 300 dpi would result in a 3333 x 2500 pixel graphic (i.e., the pixel dimensions are scaled by the ratio of the output-to-screen resolution, in this case, 300 dpi /72 dpi).
   
   
3. Improved thermal ellipsoid rendering at high resolution. The thickness of the boundary ellipse line is now correctly scaled.
   
   
4. Improved screen tool display. Ångstrom and degree symbols are now displayed.
   
   
5. Fixed a problem with changing bond styles. Attempting to customize individually-selected bond styles (via the Selection > Bonds submenu) did not always work. This problem has now been fixed.
   
   
6. Updated program badging. "CrystalMaker" is now a registered trademark, and various program graphics and packaging have been updated to reflect this.
   
   

CrystalMaker 7.0.1

Released: 9 August 2005

1. Reversible stereo options. Negative stereo pair separations can now be entered, allowing reversed 3D display e.g., using blue/red instead of red/blue glasses, or "cross-eyed" viewing of stereo pair plots.
   
   
2. Fixed a minor issue on "Jaguar" (Mac OS X 10.2) when using the Model Options window.
   
   
3. Miscellaneous bug fixes. The "List Bonds" command now works correctly. Reading CIF files with thermal ellipsoid data is more reliable; the Add/Delete Bonds tool no longer causes the program to crash.
   
   

CrystalMaker 7.0.0

Released: 11 July 2005

1. New version This program is a major update of CrystalMaker, providing the ability to work with massive structures, display thermal ellipsoids and much more.
