Following our minimum supported version policy, MODX 2.5 will be supported for one more year following the release of MODX 2.6.
We are dropping support for MODX 2.4 on April 22nd and PHP 5.3/5.4 on July 21st, 2017.
We're a bit late with the announcement, but as of August 19th 2016 we will no longer support MODX Revolution 2.3 with our extras.
All of our extras have been tested in Revo 2.5 and have been found to work as expected. With this new release, we'll end support for 2.4 in a year from now.
MODXpo is just around the corner, as is our social get-together on Friday. During this period, we will have limited support availability from November 17th (Tuesday) through November 23rd (Monday).
