In typical Open webOS team fashion, the releases for this month have come right at the very end of the month. While the System Manager Bus saw an early release back in April, this month's releases didn't come before their time. Up for July is the LunaSysMgr and the core webOS apps. For the uninitiated, LunaSysMgr is the system manager for webOS, responsible for the launcher, card view, menus, running WebKit, and rendering Enyo applications. In other words, it's kind of a big deal for webOS. The core apps include Accounts, Calculator, Calendar, Clock, Contacts, Email, and Memos, and are all the Enyo 1.0 versions of those apps (minus some features) as they debuted on the TouchPad.
On the LunaSysMgr front, the big news is both the open sourcing and the inclusion of the QtWebKit engine for "state-of-the-art support for HTML rendering and I/O". Using QtWebKit is said to provide for improved stability and performance in Open webOS. Apart from that, it's not radically different from the existing LunaSysMgr in webOS 3.0.5.
As for the core apps, they're a little handicapped at this point (not that there's much you could do with them). Even though the Accounts app was included in today's release, the services needed to enable Synergy haven't yet been open sourced, meaning you're severely limited in how the apps that rely on outside services can be used. For example, Contacts and Calendar can manage on-device contacts and events, and Email can hook up to POP and IMAP accounts, but none of them can sign into services like Google, Yahoo, or Exchange. Synergy support is expected with the beta release of Open webOS 1.0 later this month.
Things are starting to pick up steam with Open webOS as we approach the full release of the open source successor to webOS. As we move into August we can expect the build release model and the beta and final releases for Open webOS. From there, well, that's another story.
