Updates Fixes uninformative errors from mirai_map() collection when a task resolves to a non-mirai 'errorValue', e.g. cancelled or timed out (#642). Fixes mirai_map() collection option .flat ignoring an 'errorValue' in the first element (#639). Fixes daemon() returning exit code 1 (idletime) instead of 2 (walltime) when walltime elapses while idle (#637). Fixes race_mirai() not waiting for resolution on compute profiles set with url and dispatcher = FALSE (#635). Fixes daemon crash for errors raised before evaluation begins (#633). Fixes daemon cleanup not restoring options modified during evaluation (#631). Removes an ineffective promise cache from the as.promise() method for 'mirai_map' objects. mirai_map() dispatches tasks with lower per-element overhead. everywhere() dispatches with lower overhead, and errors upfront for a missing expression or invalid ... arguments. Ephemeral daemons return invisibly so that they do not print unnecessary output when this is being logged (thanks @jan-swissre, #619). Requires nanonext >= 1.10.1.
