Item #1: ChaCha20, an improvement of Salsa20. See http://cr.yp.to/talks.html#2008.01.09-1.

Item #2: Better universal hashing, http://cr.yp.to/papers.html#pema, combining the stream-processing speed of UMAC et al. with the small key size and high key agility of Poly1305 et al. See http://cr.yp.to/talks.html#2008.01.09-2 for an application to authentication (MAC1271), and http://eprint.iacr.org/2008/004 by Sarkar for an application to disk-block encryption.

Item #3: http://cr.yp.to/cipherdag/20070924.html, a prototype tool for turning people's C/C++ cipher implementations into data-flow diagrams and then experimenting graphically with the diagrams. If you've written code for automated cryptanalysis (for example, searching for differentials) and if you're annoyed at the difficulty of converting people's ciphers into input to your code, let's see whether we can hook my data-flow diagrams into your code!
