Scala 2.12.0-M4 Released

Release of Scala 2.12.0-M4

On April 11th, Scala 2.12.0-M4 was made available to the public marking feature completeness for 2.12.

M4 includes new features such as the ability to compile a trait to a single interface, Java 8-style Lambdas which can lead to significantly smaller JAR files, a new backend “GenBCode” which emits code more quickly, and a new bytecode optimizer.

Scala.lang reports that in total, 135 pull requests were merged, 16 by new contributors, and 49 JIRA tickets were resolved. You can take a look at 14 of the most significant PR’s here.

There are a few breaking changes that should be reviewed and it should be noted that Scala 2.12 is not binary compatible with the 2.11.x series.

Lightbend acquires BoldRadius

Lightbend acquires consulting firm BoldRadius

Earlier today, Lightbend, the company behind the Reactive Platform, announced that they have agreed to acquire the consulting firm BoldRadius Solutions and all of their current employees.

“The digital business boom is creating an overwhelming demand from traditional enterprises and global system integrators for Reactive technologies and expertise,” said Mark Brewer, CEO at Lightbend. “The acquisition of BoldRadius allows Lightbend to meet this demand with a well-formed team with real-world experience enabling Lightbend customers and partners.”

Brewer further explains, “Acquisition is an obvious tactic to expand our reach, but is only truly beneficial if the values of both sides are deeply aligned.”

The acquisition should be finalized over the next few weeks.
