MOLECULAR ORBITALS OF TRANSITION METAL COMPLEXES
Yves Jean, Colin Marsden

Severe bug in ORCA 5.0.1
All users are advised to update to 5.0.2 and check previous results using ORCA 5.0.1

This ORCA release is especially relevant as it fixes a race-condition in a combination of shared matrices and parallel linear algebra, leading to unreliable results and undefined run-time behaviour the more cores have been used.
Due to this bug, all users are thoroughly encouraged to upgrade their ORCA version to 5.0.2 immediately!

UCSF ChimeraX version 1.3 has been released!

ChimeraX includes user documentation and is free for noncommercial use.
Download for Windows, Linux, and MacOS from:

https://www.rbvi.ucsf.edu/chimerax/download.html

Updates since version 1.2 (May 2021) include:

- AlphaFold tool and command to get AI-predicted protein structures
- Selection Inspector to inspect/change attributes of atoms, bonds, etc.
- Scale Bar tool and command
- new BLAST Protein GUI with easier controls for showing hit info such as
source species, crystallographic resolution, ligands in structure
- Altloc Explorer tool and command to switch among alternate locations
- model loops and missing segments with Modeller
- combine or copy models
- change bond lengths
- apply command files iteratively to multiple input files
- list multiple map-fitting solutions from global search
