Google's developers clearly missed all the Halloween fun, with both the Chrome and Wave teams slinging out updates yesterday.

The Wave team has pushed out a "developer instance" of the messaging everything platform.

"One of the fundamental concepts we discussed was the vision for wave as an open communications protocol. We are happy to announce that the developer instance of Google Wave is now available for experimental interoperability testing with other wave providers," the relevant blog posting reads.

Anyone wanting to build a service built on the ominous-sounding Google Wave Federation Protocol can peruse introductory docs and more via Google, and of course submit feedback. More details here.

In the slightly less nebulous world of Chrome, the firm has popped out a new beta, promising "a few new treats and cool tricks".

Well, one new treat/trick, it seems, in the shape of bookmark sync, which allows bookmarks and subsequent updates to be mirrored across multiple machines.

If you've only got the one machine, or would prefer your home surfing not to be reflected on your work machine, the new beta still promises a 30 per cent speed increase over the most recent version.

The new beta is downloadable here. ®
