- Update for RimWorld 1.4 and 1.5 (beta)
- Default convection conductivity increased from 10 to 20, and terrain insulation increased by 1 point
- New setting: offset mountain temperature by a certain amount (e.g. to make them a few degrees warmer than the annual average)
- Made freezing/melting system more flexible: it now affects all terrains with tags Freezable and Meltable. Allows mods to add e.g. non-freezable water and custom ice
- When ice is generated on new maps, it can be covered by snow (experimental)
- Autoignition can increase the size of the existing fire
- Added patches for Dub's Bad Hygiene, Layered Wall Destruction, Simple Chains: Steel, VFE Medieval
- Fixed Vanilla Furniture Extended (Architect & Medical) patches
- Other tweaks and optimization

*Two-year anniversary update*
- Geysers and other similar large objects now produce heat from their entire area, not just a single cell. It should also prevent some highly exothermic modded buildings from quickly overheating.
- Changed how thermal properties are defined for a cell, which should make Replace Stuff's vents and coolers work correctly even without a patch.
- Added support for Vanilla Vehicles Expanded (garage doors)
- Removed support for walls in Insulation (Continued) due to how they are implemented
- Added some debugging and logging goodies and null checks

- Autoignition is now checked more frequently (at every update)
- German translation updated (thanks @ntninja)
- Added null checks to avoid compatibility issues with Windows & some other mods
- Celsius now tells the game to be placed after its dependencies

- Added German translation (experimental, thank you @ntninja)
- Freezing and melting are now checked more frequently to reduce stutter
- Roofs now let heat through; their insulation is tweakable in the settings
- Direct sunlight now warms pawns and slightly lowers their comfortable temperatures
- Update interval can be reduced (for greater physics accuracy) or increased (for performance) on the go
- Conductivity stat replaced with Insulation (information only)
- Optimized environment temperature handling causing up to 30% overall performance improvement
- When ice melts, graves only eject corpses if they are destroyed

First Celsius birthday update!

- Vents now initialize in a correct state (i.e. open) when built
- Heat capacity and conductivity stats now show on unbuilt things as well (e.g. in Architect menu) and are more informative
- Ideology DLC: ritual fires now produce heat
- Biotech DLC: waste packs should contaminate environment when they sink in water upon melting (untested)
- VFE Architect: fake woods have proper autoignition temperatures (same as vanilla wood)
- Improved handling of switching the freeze/melt feature on and off during the game
- Some further code optimizations (5-10% performance improvement in my tests)

- Added support for localization (big thanks to @tinygrox). I don't plan to create any translations myself, but feel free to submit yours.
- Winds and being wet (having the "soaking wet" thought) now affect pawns' comfortable temperatures. It can be disabled in the settings.
- Water and ice heat capacity and insulation are increased; water now freezes at -0.5C, and ice melts at +0.5C. It should reduce the number of freeze & melt cycles each year.
- Added a patch for Alpha Animals and improved support for VFE Architect
- Drowning in melting ice now happens via a new hediff and damage type, so that the game's notifications are more immersive (pun intended)
- Settings dialog is now scrollable
- Some optimization of freezing and melting
- Renamed stats to avoid potential collisions with other mods

Celsius 2.0: Major update (RimWorld 1.4 only)

Main changes:

- Much of core code rewritten from scratch. I found ways to get rid of main drawbacks of the old methods (such as limits on how fast heat could travel) while fixing lots of bugs and streamlining the algorithms.
- Saves from Celsius 1 are automatically converted. Mid-save downgrading from Celsius 2.0 to Celsius 1 is not supported.
- Rebalanced all thermal values (except autoignition temperatures) for vanilla and modded buildings, terrains and stuff. Most problems with building thermally efficient bases and ice that wouldn't melt should hopefully be resolved (or at least resolvable) now.
- Heat conductivity now depends on Insulation and is measured in percent. Its stat page now has detailed explanations. Heat capacity is also a more abstract value.
- Better handling of ice melting, e.g. buildings, pawns and other things may drown when they fall in deep water.
- Melting and freezing now always happens at 0C.
- Now showing correct temperature at the specific cell in the bottom-right corner of the screen.
- Full support for Windows mod including open/closed states of windows.
- Optimized the code so that the mod should run even smoother than before despite being more accurate and powerful.
- Fixed an unknowable number of bugs. Then probably added some more.

- Open doors now let through more air; vents are more efficient
- Snow now melts faster under rain
- Snow disappears if ice underneath has melted
- Fixed issues when a map already has ice on it
- Disabled profiling & reduced unnecessary logging => slight performance improvement

- Updated for RimWorld 1.4
- Celsius now replaces vanilla temperature overlay
- Added options to use vanilla temperature colors and to disable cell/terrain temperature tooltip
- Reduced environment convection (from 50% to 30%) and heat push (from the factor of 10 to 4 compared to vanilla); the former setting is not automatically changed in existing games
- Temperature overlay button only works now when no tabs are open to prevent conflicts

- Adjusted some default settings: lowered convection conductivity effect from x200 to x100 and air heat capacity from 3000 to 2500 J/C. It won't affect existing configurations, so you are advised to reset the settings yourself.
- Fixed temperature toggle hotkey remapping not working and having a wrong label
