  • feature | Nginx has been upgraded to version 1.20.2. (SVM-3368)
  • feature | PHP has been upgraded to version 7.4.26. (SVM-3367)
  • feature | Replaced gzip with zstd in AutoFTP-backup/restore operations for OpenVZ containers on EZ-templates. (SVM-1890)
  • feature | New parameter throttling in /usr/local/solusvm/data/disk-scrubbing. Details (SVM-3161)
  • bugfix | Not possible to migrate KVM (Xen) VPS from CentOS 6 node with enabled compression. (SVM-3317)
  • bugfix | PHP is not upgraded to 7.4 on Centos 7 if Epel-repo disabled or not installed. (SVM-3323)
  • bugfix | Backup creation with zstd-compression fails for OpenVZ container on EZ-template if there are socket files inside the container. (SVM-3350)

  1. In case there are customizations in /usr/local/svmstack/nginx/conf/mime.types file or in /usr/local/svmstack/nginx/conf/nginx.conf file, they will be overwritten during the upgrade.

  2. If there are custom directives specified as custom configuration files at /usr/local/svmstack/nginx/conf/conf.d/ directory, check if those directives still work on nginx version 1.20.1 using nginx documentation.

  3. Now backups of OpenVZ containers on EZ-templates are created with zstd-compression (*.tar.zst) instead of gzip-compression (*.tgz). It provides faster backup/restore operations with lower HW-resources utilization and better compression.

  4. Script /scripts/ftp-restore supports both old and new backup formats.

  5. Current rotation cycle is not interrupted on the format switch.

  6. Backups in zstd-format cannot be restored on CentOS 6 nodes (EOL).

  7. In order to ensure backups integrity this update should be installed at time when no backup is running.
