DPM news

See comments about LFC.

LFC news

LFC 1.7.4-6 is now the recommended version for SLC5. For SLC4 it is still 1.7.3 due to an issue with the VOMS library.

LFC 1.7.4-7 is in staged rollout but the only difference is some fixes for the Python 2.5 interface.

FTS news

FTS 2.2.5 (supporting sites without SRM and .lsc files) will enter certification next week.
