Following the release of Chrome 17 earlier this week, Google has begun the early testing phase of Chrome 19 with developers and adventurous users. Since Chrome 18 is already in the beta stage, we can expect to see Chrome 19 come in stable form in either late March or early April.

While exact release notes are scarce, we can already see that Google's Chrome 19 will include a new spellchecker that is powered by the web giant itself. Users must first "opt" themselves into using the service, however, and it's not clear exactly how this is different than the web browser's current spellchecker.

In addition, Chrome 19 brings initial support for Mac OS X Lion's "Resume" feature, which allows applications to be closed and later opened in the exact state that they were left in. Chrome sees support for this with open websites in tabs, which desktop space you left it in last, and whether it was in full-screen mode or not.

The latest build of Chromium (the current testing build of Chrome 19) is available for download here.
