Bloks 2.8.2

Restores unpack into folders of their own, and spent one-time routines make room at the limit.

• One-time routines no longer fill the limit. A routine that runs once stays on the books afterwards, switched off, and still counted toward the fifty you can have. Fifty of those refused every new routine with nothing left that could run. At the limit, the one that ran longest ago now makes room. A routine that can still run is never dropped. Thanks @rpavlovs (#276)
• Two restores in a row, again. A second restore staged in the same second used the first one's unpacked folder and cleared it. Each now unpacks into a folder of its own, and the one left behind is cleared when a restore is put in place. Thanks @ashottonoyan (#273)
• The restore log names the right folder. After a restore that had to set the old workspace aside under another name, the log pointed at the folder that was already taken. It now names where the workspace really went. Thanks @ashottonoyan (#274)
