After the update mongodb and mongo module is a deprecated and does not support , I decided to write a new module for Kohana.The module itself : https://github.com/foozzi/kongodbI would be grateful for the support and finding bugs .All bugs please write in https://github.com/foozzi/kongodb/issues
Now under the Kohana has adequate new module for mongodb.
Could you instead of creating separate module, integrate your changes with fork of kohana database module?
