0.9.17 is primarily a bugfix release, but it also continues our migration to stronger cryptographic signatures.

We have moved the news feed system used for the news on your console and the latest router version indication to a signed format using RSA 4096-bit keys for enhanced security.

New eepsites and servers will be ECDSA-signed by default, if ECDSA is available. There is now a warning in the console sidebar if ECDSA is not available. For RedHat users, we have reports of successful installs of the BouncyCastle Provider (bcprov) jar to add ECDSA support.

We've fixed several serious bugs, including an SSU packet corruption problem, and a SAM bug affecting i2p-messenger and other SAM applications. There are several fixes for the preliminary ECDSA router signatures added in the last release but not yet enabled.

Many of us will be attending 31C3 in Hamburg in December. Stop by our table and say hi!

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.
