The release happened actually more than a week ago, but it is only now that I got around to write about it.
The release brought very little of new formalized mathematics. Most of the effort went into getting the TiddlyWiki rendering work with more IsarMathLib theories. This requires improving the Isar parser and modifying the theories to conform to the Isar dialect that the parses assumes. As I modify the theories the Tiddly Formal Math site content diverges from the last released proof document and this release fixes that. The only significant change was the addition of a small tutorial on reading Isar formal proofs in the new Introduction.thy theory.
The IsarMathLib’s TiddlyWiki rendering got some praise on the Mizar mailing list recently.
