New Diamond Version 4.6.3

April 7, 2020

A minor update 4.6.3 of "Diamond", our software for crystal and molecular structure visualization, has just become available. This new version corrects several bugs:

  • The following bugs have been resolved:
    • Some bugs with the "Build/Expand..." command and dialog that prevented H-bonds to be used or created during the expansion from one molecule to another/neighbouring one, although defined on the "H-bonds" page of the "Build/Connectivity" dialog.
    • "Build/Connectivity...", "H-bonds" page: When editing "Standard H-bonds" the edited (atom type pair based) settings could be appended rather than overwriting the previous settings.
    • When using commands "Expand direct" from the toolbar or local context menu (i.e. skipping the Expand dialog that "Build/Expand" shows), D..A (donor .. acceptor) contacts from H-bond definitions were not yet considered.
    For details, see the "Known Bugs" page.

Diamond version 4 customers should use the online update function (menu "Help/Online update") or check the "Diamond Version 4 Update Page" for alternative update choices.
