• Added the biome_rain_effect datapack, which currently includes the types none and fog; the snow and rain types will be introduced in version 0.12.2.
• Debugged certain initialization methods of Fog rendering to avoid issues under specific startup conditions.

0.12.1

• Added seasonal ritual: after crafting the Greenhouse Core Container, it can be activated with a Seasonal Prayer Scroll to begin the ritual and obtain the Seasonal Greenhouse Core. Be careful not to place it directly on the ground.
• Added an experimental fog rendering feature, currently appearing during rain when enabled.
• Added a new display mode for the calendar that shows the current solar term day.
• Added optional datapacks “Rain Together” and “Snow Together” to synchronize weather across biomes, requiring configuration to be enabled.

0.12.0.5.1

0.12.0.2.1

• Adjusted the model settings of the Snowy Grass Block to be compatible with resource packs like Open Lower Grass.

0.12.0.2

• When querying a block’s snowy type, a null (empty) object is now used by default to maintain consistency. This also helps prevent certain Fabric mods using connectors from triggering queries at incorrect times (such as when a chunk is not fully loaded), which could otherwise cause chunk reload loops and server deadlocks.

• Slightly optimized particle effect rendering and generation performance.

• 0.12.0 - First Official Release – Anniversary Edition

  On this special anniversary, we proudly present our first official release! While there may be no significant content changes, this version sets the stage for stability and marks the beginning of a long-lasting experience. Moving forward, expect fewer frequent content updates, focusing instead on maintaining and refining what we’ve built.

  • Spring After Autumn achievement now unlocks a commemorative reward: Snowless Hometown—a symbol of warmth and the passage of time.

0.12.0-z-3

• Now, when it’s snowing, a cauldron filled with water will turn into an ice-filled cauldron, and a cauldron filled with powder snow will turn into a snow-filled cauldron.
• Fixed a potential world initialization crash that could occur when SereneSeasonsCropTag is enabled and an agriculture mod provides both Forge and c namespace tags for the same seed.
• Blocks containing water are no longer affected by the Frozen Water feature. And the Frozen Water feature is now affected by light levels.

0.12.0-z-2

• Fixed an issue where the calendar displayed incorrectly in Next mode when it was the last solar term of the year.
• Added a more complete built-in compatibility system for crop growth conditions. Note that humidity requirements are now included; if you encounter errors, you can disable this feature in the settings.

0.12.0-z

• Enabled ForceCompatMode by default, since many crop-related mods do not use Forge crop events. Forced compatibility essentially restricts random block ticks; if issues occur (though unlikely), you may try disabling it.
• Optimized data recording and caching fields for the “Spring Gone, Autumn Come” advancement. This change invalidates old version data, but it improves tracking of how many seasonal cycles a player has passed, allowing for special use cases.
• Added a special extra_info data pack for prioritizing Ecliptic Seasons’ data packs and removing built-in registrations. For example, biomes can now use an independent argo climate without overriding the built-in argo files. This applies to all mod-provided data pack registrations; please report if you find cases where it doesn’t.
• The FrozenWater feature now requires SnowyWinter to be enabled first, keeping it consistent with existing seasonal mechanics.
• Added temporary caching to server-side global weather parameter calculations when Solar Weather is enabled.
• Optimized the snow reflection parameter object during Iris loading, now aligned with the snow block rather than the snow layer, fixing distant transparency issues in certain shaders (e.g., Complementary Shaders Unbound).

0.12-preview
