To install the Lion Developer Preview, you'll need 10.6.7 or the previous developer preview which, again, needs to be updated in Software Update. For those who will need to pause their download from the Mac App Store and resume it, Apple says in the FAQ section:
If you need to interrupt your download for any reason, including changing the network you are connected to or traveling to a new location, ensure that you first Pause your download under the Purchases tab in Mac App Store. After you re-establish your connection, you may Resume your download under the Purchases tab.
While TechCrunch reported a few days ago that Apple would soon release a "GM" version of Lion to developers, it clearly appears that Lion still needs a few more updates before being ready for the golden master status. Several bloggers are speculating that a GM version will actually be released at the WWDC, which will kick off in San Francisco on June 6th.
Changes in the Lion Developer Preview 2 are still unknown. We'll update this post as we gather more details.
TechCrunch now follows up to their previous report with details on today's build:
More importantly, this is the build that Apple is considering to be a “GM1″ revision internally, we hear. And yes, it’s said to be much more stable and complete than the previous build.
Having said that, it’s unlikely that this will be the actual “Golden Master” copy. We’re still a solid two months away from Apple’s WWDC event where Lion will be a key area of focus. Apple may attempt to launch Lion there, but more likely is that the release candidates is handed out to developers there.
