## Acknowledgements and Changes

**2021-06-19** Thanks to @Deusovi for a better ruleset and also to @Portponky, @Zach, @Hempuli for inspiration, plus @TheGreatEscaper, @Menderbug, @TJM, @dohz, @Hempuli for feedback on the puzzles and/or on the wording of the "turning rule".
**2021-07-09** [Subwhirl] error checking now accepts an interesting loophole, successfully exploited by @Karoo.
**2021-07-09** Thanks @dohz and @Karoo for the suggestions, puzzles and feedback! 
**2023-12-03** Added directional aux marks to subwhirl, a suggestion by @Muhorka.
**2024-03-13** Two puzzles by @PinkHoodie revived [subwhirl]; one using the ´´no-crossing´´ variant. The Enigmarch "wave" theme seems very fitting. Thank you!
**2024-03-15** A third puzzle was created by @PinkHoodie - thank you!
**2024-03-17** :::puzzletters @AnuragSahay sent a [Subwhirl] puzzle - thank you!
**2024-03-18** An encoding regression in older puzzles (using the non-parenthised number format) found by @Sophie was patched. If any of your puzzles used this format, please consider re-opening, interacting (draw/erase a line), and re-saving them the current format.
**2024-03-24** @PinkHoodie made a third small classic [Subwhirl] - thank you!
**2024-04-10** The very difficult [panel modernisation|../panels#modern] of [Subwhirl] was achieved by @PinkHoodie, a herculean effort. Thank you! Also, multi-loop colour variegation was added.
**2024-05-26** A recent regression detected by @MonokuroGreen was corrected (cause: changes in the arrowhead marker templates)
