Each of the last major versions of Joomla (1.6, 1.7 and 2.5) have some important differencies in core code which have influence on page caching operation. From this reason it was necessary to develop specific solutions which are working only limited on one major version. With coming new long-term supported Joomla 2.5 here are also new version of JotCache, ver.2.0.6. This version has now all functions implemented which are known from versions for Joomla 1.7 and 1.5 (JotCache version for J1.6 is not more developed). But of course some small obstacles related to PHP 5.3 (deprecated functions) were solved for coming JotCache 2.0.6 for J2.5. Download of installation file you can find here. The description of JotCache operation and administration is presented in JotCache 2.0 Help.
