[01:14:46][@donotputmeonpizza][I'm guessing that without specifying some sort of optimization flag, there will still be some optimizations done, which you want to explicitly not do?]

Cinera 0.7.0 Update Add output parameter to all of hero/code, hero/intro-to-c and hero/misc, preserving the current URLs while allowing different .hmml filenames, notably for hero/misc which now gets sorted chronologically.

Relocate riscy and add newly converted hero The idea here is to reduce the amount of superfluous stuff downloaded to each server running cinera 2017-12-06 22:26:13 +00:00			`[00:01:09][Plan for the day]`

Fix some incorrectly converted annotations Also apply some :speech categorisation 2018-03-07 21:48:09 +00:00			`[01:08:19][Q&A][:speech]`
