0.9.39 includes extensive changes for the new network database types (proposal 123). We've bundled the i2pcontrol plugin as a webapp to support development of RPC applications. There are numerous performance improvements and bug fixes.

We've removed the midnight and classic themes to reduce the maintenance burden; previous users of those themes will now see the dark or light theme. There's also new home page icons, a first step in updating the console.

As usual, we recommend that you update to this release. The best way to maintain security and help the network is to run the latest release.
