This will be the last release to support macOS 10.14 (Mojave).
Also, ChimeraX 1.4 is not available for CentOS 7, Ubuntu 16.04 and 18.04 because the Qt 6 window toolkit does not support those older Linux distributions.
Updates since version 1.3 (Dec 2021) include:
- search/retrieve from EBI AlphaFold DB 3rd release, ~1 million structures
- display AlphaFold predicted aligned error (PAE) plots
- can BLAST UniRef100,90,50 (+ previous choices AlphaFold, PDB, NR)
- AlphaFold prediction of multimers (of limited size) on Google Colab
- independent centers of rotation available as mouse mode
- join models with Build Structure tool or command
- define axes for display and/or use in measurements
- increase/decrease VDW radii relative to their current values
- switch PDB residue numbering scheme (author/canonical/uniprot)
- align sequences with Clustal Omega or MUSCLE
- calculate % identity in sequence alignments
- window toolkit updated to Qt 6.2.3 from 5.15.2
