Unfortunately it is unclear to me how many current bugs/issues are related to stable version. On another side, I do not like to use stable but crippled versionthere are some fixes that are going to 2.066, and there is the plan to eventually release 2.066.1 (already here), 2.066.2, etc. with those fixes incorporated. so it should be fairly good to just stick with 2.066 and upgrade it when new minor version released, if you don't need thatshiny new features (and bugs ;-).
Thanks
