Updater V1 technical details

I'll use this page to document the changes made to the ImageJ Updater in the about to be released version called V1.

What's different

  • Added a check whether Java version supports the HTTPS certificates.
  • Depending on what's supported, the updater will use HTTPS or HTTP links for the update sites on imagej.net (and throw a warning in case HTTPS is not supported)
  • Uploading via HTTPS is working now, both basic and digest authentication supported
  • The updater is smarter about updating URLs of official sites (= listed on the list of available update sites) in case they change remotely
    • It shows a approval dialog for activated update sites, when the URL changed in the official list of update sites.
    • Supports migration from http to https for sites.imagej.net.
