• Models now can contain up to 500 atoms (instead of 400).
• Hide function
• Recognition and special handling of organomet. pi-Bonds (e.g. Ferrocene).
• Powerful and fast search functions (Element, Label, Group, Protein Backbone, DNA/RNA Backbone).
• Interactive Make/Break bond.
• More selection tools (to back, to front, in radius, same molecule).
• Improved import-mechanism.
• Data integrity: no coordinate rounding errors even after ten thousands of rotations.
• Greg's Buttons shareware utility: now more compatible, but you must switch OFF all of its colorizing options (finder windows, menus, dialog boxes and alerts) before running MicroWorld!
• Several bugs removed.
Changed functionalities:
---------------------
• The rarely used display-option 'Brighter with Distance' has been removed.
• The ability to display up to 16 element colors per model has been reduced to an upper limit of 12 colors. This gave way to more depth in the color representation.
• Requires at least 256 colors. The 16 grayscales representaion has been discontinued because of its poor quality.
What you need to do:
------------------
Generally, file compatibility to MW 1.2 files is guaranteed. However, some minor modifications might be necessary:
• Throw away your old MW-Settings file (System 7: in the preferences-folder; System 6.0x: in the same folder as MicroWorld). Microworld 2.0 will then generate a new one when launched.
• Since the element color palette has been reduced from 16 to 12 colors, all assignments to the last 4 colors in the dialog now are re-defined as undefined element color (last entry in the dialog). You might want to re-assign these.
• Old MW-pictures are automatically recalculated to the new color palette when opened. Please save them again after this process, in order to prevent such recalculations in the future.
