Introduction
The EGI Staged Rollout is a procedure by which certified updates of the supported middleware are first released to and tested by Early Adopter sites before being made available to all sites through the production repositories. This procedure permits testing an update in a production environment that also is more heterogeneous than what is possible during the certification and verification phases. It allows for potential issues with an update to be discovered at a small scale and potential workarounds to be added to the release notes. In some cases an update may even be rejected. The Staged Rollout serves to increase the confidence in the quality of the updates that pass, such that the vast majority of the sites should experience smooth updates. Sites are invited to participate in the Staged Rollout for services that they have a particular interest in, with the proviso that they may need to debug issues with a particular update and in any case should report their findings. Such participation can be of great value to the production infrastructure and is appreciated!
Reminder: members of Early Adopter teams need a EGI SSO account.

Collaboration between EGI and WLCG
EGI received an expression of interest from WLCG to integrate the WLCG Middleware Readiness working group. The main goal of this group it's not only to improve the quality of the middle-ware products available to the WLCG sites but also to increase the speed at which new products or releases are available to sites while avoiding the duplication of effort. This could be achieved by sharing experiences and improving the communication channels of both communities.
The work, discussions, meetings, technical information will be handled in this wiki page: [WLCG Middleware Readiness]
