 ## Changelog for Cristallina computational issues
+- 08.01.2024:
+  - updated analysis_edge, analysis_forge, flet, slic environments. Should improve collaboration features, only small changes otherwise.
+  - checked on general RHEL8 update status. This failed on several consoles due to not enough space on /var. 
 - 18.12.2023:
   - updated environment: analysis_edge for jupyter_collaboration 2.0.0. 
   - updated Saresc-cons-01 as a test for other consoles as RHEL8 were not applied. Also removed ancient flameshot, now only installed one is 12.1.
