Starting in Sytist version 0.8.4 is a new auto update feature (so when 0.8.5 comes out you will be able to use it). The upgrade process will take less than a minute.
You will receive a notification on your admin home page that a new update is available. Just click the link to get started.
Basically what happens is it will :
- Attempt to fetch the upgrade zip file from the PicturesPro.com server.
- Unzip the zip file
- Make a backup copy of the Sytist files into a backup folder.
- Move the new files into the correct locations.
After that you just have to refresh your admin page and edit your theme and save to complete it. Screen shots of the process below. If for some reason this fails (due to server restrictions or permissions), you will still be able to manually update.
