upgrade your stable Slackware system to Slackware “current”:
1. Set your preferred slackware-current mirror by uncommenting the relevant line in /etc/slackpkg/mirrors.
2. Update package list: # slackpkg update
3. Install new packages: # slackpkg install-new
4. Upgrade all installed packages: # slackpkg upgrade-all
5. Run the above again (due to recent switch from TGZ to TXZ packages): # slackpkg upgrade-all
6. Remove unneeded packages: # slackpkg clean-system
7. Repeat steps 2, 3, 4 and 6 once or twice a week to ensure that you are always in sync with the “current” development.

note: step 5 really should read “run 2,3,4 again now that you have the latest package tools”
