After fixing a couple more bugs in Tellico, I figured I could go ahead and release another version. Tellico 0.13.4, a.k.a. Jeff Gordon on skis is available. The changes include:

• Fixed a bug with the RIS importer that messed up all entry
  types.
• Fixed a bug with Amazon.com character encoding for non-latin1
  characters.
• Fixed a bug with exporting empty groups in HTML.
• Updated and fixed the bibtex character translation table, which
  should finally be correct.
• Added a configure parameter to disable compiling with cddb
  support even if the kcddb headers are found.
