There is no time limit set for how long SlideDeck 1.x support will last at this time, however this may change in the future. If you have a SlideDeck 1.x license you got free upgrades within the minor revision of 1.x - the latest being SlideDeck for WordPress 1.4.5 and SlideDeck jQuery 1.3.2. If you are not running the current versions listed, please contact us and we can send you an update to 1.4.5/1.3.2
With the release of SlideDeck 2, future updates/upgrades for the 1.x versions will be halted, apart from bug fixes etc. So if you would like to keep up to date with the latest version, please visit our site and purchase a license.
SlideDeck 1 has been sunset as of March 15, 2013. We had a good run, and are happy with what we have achieved. Check out SlideDeck 2 to see what's new.
