I can't find the version number of the Quest program on the Quest site.
I need to know if I have the latest version of Quest installed on my computer.
Is there a log of updates done to quest?

After clicking on Download for Windows I now can see the version number on the download button.
I still need to know if there is a log of Quest updates please.

When you have Quest open, click 'Help' >> 'About'. This will give you the version number.

Then go here and click on 'Previous version' : http://textadventures.co.uk/quest/desktop

Update logs are on the blog: http://blog.textadventures.co.uk/

Quest checks for updates when it starts - there's a big yellow banner that appears underneath the game browser if a new version is available.

there's also this page too for version history:

(it's actually a really useful page, btw)
