This release comes across as quiet, containing just the usual assortment of braille table improvements, cleanups, bug fixes and the classic buffer overflow patches. But beware, a lot has happened behind the scenes. Bert and Davy have been adding a new opcode to handle special emphasis situations. A number of annoying restrictions with regards to names, such as class names have been removed thank to Bert. And lastly also thanks to Bert it is now possible to define inline display tables in your YAML tests.
