OCRopus 0.5 was released a few weeks ago on Google Code. There are a lot
of changes relative to older versions:
- OCRopus has been completely refactored and now consists of a set of
Python modules, with some native code modules.
- Unicode and ligature support should be fully working now.
- Language modeling still uses finite state transducers, but all finite
state transducer code has been refactored into ocrofst.
- There is a completely new recognizer that performs much better than the
old recognizer and scales to millions of training samples.
- Databases for training/testing have been changed from SQLite format to
HDF5 (using PyTables).
- You can pull over everything you need for an install using a single
command ("hg clone https://code.google.com/p/ocropus";)
There are some videos on Google showing installation and training:

There is also some additional documentation here:

Image preprocessing and layout analysis are still basically the old
versions from OCRopus. They are still fairly sensitive to noise and will
be replaced in future releases.
