Spark 0.6.1 and 0.5.2 out

Today we’ve made available two maintenance releases for Spark: 0.6.1 and 0.5.2. They both contain important bug fixes as well as some new features, such as the ability to build against Hadoop 2 distributions. We recommend that users update to the latest version for their branch; for new users, we recommend 0.6.1.
