Yes, first item of business - the official announcement of news that has been showing up here and there already. The upcoming release, that was previously referred to as 2.3 has been renamed to 3.0. :-) After long discussions we decided that the return of CiviReport, together with many other changes and improvements that have been introduced in this release deserve a major version number.
As mentioned previously, we’re introducing quite a few new CiviEvent features in CiviCRM 2.3. Most of them are still undergoing our internal CiviCRM QA cycle, but do check them out at our CiviCRM 2.3 sandbox if you’re interested (there is still time for some minor fixes to accommodate your use-cases!).
CiviCRM Multi-Org refers to the ability to support multiple owner organizations (usually a hierarchical structure of umbrella orgs and sub-orgs or local chapters) and keep some data siloed in each org while allowing other users to aggregate data across orgs too. It has been been a tough nut to crack. But I and the organization I work for (The Public Interest Network) are committed to getting it working in CiviCRM 2.3.
