v1.1.1
Download marvel-reading-tracker-windows.zip below, unzip it anywhere, and run Start on Windows.cmd. Node is bundled, so nothing needs installing.
Upgrading from 1.1.0 is safe. Your reading progress lives in your browser against http://127.0.0.1:8787/, not in the folder, so replacing the folder does not touch it. There is nothing to back up and nothing to migrate.
What changed
If the tracker could not start because something else was already using its address, the message it printed told you to run a command this download does not carry, and suggested a different address that would have shown you an empty tracker with none of your reading in it. Both were wrong for anyone using the download rather than a developer copy.
The message now tells you what to actually do: check whether the tracker is already open, and if it is not, close whatever else has the address. It also says plainly not to move the tracker to a different address, and why, since that is the one thing that looks like a fix and quietly loses sight of everything you have marked as read.
This was found by starting this download and letting it fail, which is why it could not have been caught before there was a download to start.
Nothing else about the app has changed.
