Version: 0.2.1
Date: 2020-03-17
  Info:
    - The previous owner of "Will-o'-the-Wisps updated" (mk-fg, who has retired from Factorio and modding for now) suggested that somebody should release an update for this mod. As I've already updated it for my own use, and because I also have made a mod that is useless without this one, I'll upload my local version. (https://mods.factorio.com/mod/Will-o-the-Wisps_updated/discussion/5e4921a23c3040000ea61c4b)

    - Please note: I don't really have the time and energy to maintain this. It's intended as a one-shot upload, just so this great mod will be kept alive for Factorio 0.18. If RocketManChronicles (the current owner of "Will-o'-the-Wisps updated") ever updates the original version, I'll deprecate this again.

    - If you have the time, will, and ability to maintain this, please contact me! I'll be happy to transfer ownership to you in this case.

  Changes:
    - Updated for Factorio 0.18.
    - Added "icon_mipmaps = 1" to icon definitions in order to prevent logfile spamming.
