## [0.90.1] - 2026-09-14
### Added
- Actions that will or may end the current case now carry a clear warning label and require confirmation before proceeding, without revealing the resulting ending.
- Added a dedicated Companion section above Items in the investigation sidebar. It shows active bilingual companion states and remains hidden when the investigator has no companion state; single companion and item entries omit the redundant `x1` count.
### Fixed
- Hid internal Mountains route markers such as `branch_fast_pursuit` from the player-facing Items list; all visible evidence and companion states retain bilingual labels.
### Changed
- Following positive player feedback, the consequence-driven **New Mountains of Madness ** has replaced the original **The Mountains of Madness** case. It now occupies the existing Mountains entry without a separate Beta listing, while active Beta saves migrate safely to the promoted case.
- Expanded **The Mountains of Madness** from 19 to 31 story nodes by reworking distinctive locations from the original case—including the dog lines, dissection tent, weather station, specimen mounds, ice-cave cache, windswept ridge, mural hall, spiral ramp, sunless river, cold-storage cavern, and archive vault—into the consequence-driven structure. The mutually exclusive choices, fail-forward checks, Dyer relationship states, and multiple endings remain unchanged in principle.
- Expanded the restored scenes with period cosmic-horror narration closer to Lovecraft's Antarctic tale, and rewrote awkward or overly literal Traditional Chinese passages while keeping action labels direct and readable.
## [0.88.0] - 2026-09-14
### Changed
- Expanded **New Mountains of Madness ** with functional companion state: Dyer's trust, availability and injuries now alter routes, provide clearly labelled conditional check support, determine whether extraction is possible and unlock four companion-specific endings with correctly matched reward tiers.
