There's a new leisure release, 5.3.1.0. Upgrading is highly recommended, so upgrade as soon as you can.
This release has some important bug fixes along with some new improvements and features. One of the most important of these fixes is related to a bug that would stall the wallet when starting up in certain cases.
As well there's a fix for a bug where a beacon would be auto renewed at just the wrong time causing magnitude to be 0 (temporarily) on the next superblock
Something else notable in this release is some changes to checkpoints in the wallet. This may help catch some future issues with forked nodes spamming bad block and currently may help some of the remaining forked nodes realize they are on a fork.
