I just downloaded and installed the .paf version of Calibre ebook reader and converter, version 0.9.16). It is a partially supported developmental test release but it works pretty well. It opens and converts epub to pdf like a charm.
When I open the application I get a notice that a new, updated version is available. When I click on the update button I get taken to the home page for Calibre where it shows an update to the latest version (0.9.42) as a full update with a .exe extension. I gather from this that it will either remove and replace or replace the version I have.
So my question is how to update my portableapps version? Right now I haven't updated Calibre and am running the portableapps developmental version.
Is there a clean and safe way to update, or is it better to wait until the portableapps developer posts the latest version?
