The links from previous announced versions in topics usually redirect to the current version, the above link included.
If anyone does want a link to a previous version download they can be found at the link below.
Comodo Dragon at FileHippo
Further enough captainsticks I understand now
also for comodo on filehippo on getting a previous version download they can be found on there but under Latest Updates and you have to scroll down and look for it.
Under Browser & Plugin it only shows current version.
Also there is a shortcut. When Comodo Dragon gets updated and you wish to go back after you upgrade! then you can by looking on Filehippo, And Look under Latest Updates and then press the latest version and wait till page loads then look at the right side to get the last build. If you don't see the Latest version there just for filehippo to update then you can do it.
I just thought I let you know and others.
