(Edit: the patch 1.42.1 was uploaded, fixing the crash with C++ library not loading.)
This update adds Nanites Absorber and its upgrade, reworks Improved Map System into gameplay option, does a number of enhancements over title screen, implements new PRNG generator and implements daily seeds! As you can see, this is very Cave Random update.
(Japanese translation will come soon.)

- Added Nanites Absorber as chest loot.

- Added Military Armament as craftable item.

- Reworked/nerfed Gravity Necklace: now can be used regardless of being on the ground, but has 1.5 seconds cooldown to compensate.

- Switched the generation order of multitile structures, like clouds, and pickups, like chests.

- Weapons can be now turned into weapon items with pressing Ability key while having them selected.

- Weapon switching is now also accessible if you press Dash key on weapon items.

- Replaced the movement section of tutorial signs with new inventory management section.

- Implemented daily seeds functionality: they set the same seed and playable character each day as long as players have same gameplay options that can affect worldgen, such no Polar Star or no Nemesis. Daily seeds can be replayed as long as player doesn't record their final score for it via dying or winning.

- Removed Improved Map System as chest loot. It is still available for older saves, but will not work properly.

- Added Map System Type as Configuration option, which defines, what kind of map should be used on pressing Map: Normal or Improved.

- Switched both normal and levelgen randomization from multiply-with-carry to PCG (more info on https://www.pcg-random.org/)
