Nightlies and Releases u Introducing new modus operandi to release AA projects – The main goal is to reduce the ‘time-to-user’ u We would be releasing all the projects from what is currently working in the nightlies – Experiments make requests (bug fixes, new functionality) – These changes/additions are made available and tested with the nightlies » Tested internally with all the test suits » Validated by the experiments – The experiments may request a release at any time » What is working and has been validated in the nightlies gets tagged » The binaries for all the packages are produced centrally (by SPI)

Current Nightlies Slots u Current slots – “dev” - preview of LCG_54 » slc 3, slc 4, osx, win – “dev 1” - integration of changes to LCG_53 x » it includes a gcc 4. 1 preview in addition – “dev 2” - used by Gaudi pre-releases – “dev 3” - like “dev 1” but with Python 2. 5 – “nightlies-devel” - intal use by the nightlies u Towards LCG_54 – we need to clean “dev” slot as soon as possible
