 # Changelog
 
+## 0.2.0 (2026-03-17)
+
+- Fixed: memory context (Working Memory + recalled knowledge) no longer injected into system prompt, which was breaking LLM prefix cache and causing full KV recomputation every turn. Context now injected via `build_prompt` hook into user prompt space. System prompt stays static and cacheable. Contributed by @frostming.
+- Changed: `system_prompt` hook now returns only static behavioral guidance (identical every turn), preserving prefix cache.
+- Changed: memory loading moved from `load_state` hook to private `_load_memory` method called from `build_prompt`.
+- Changed: skill directory renamed from `bub_skills/` to `skills/` for consistency.

+## [0.6.14] - 2026-03-17

+### Added
+
+- **Configurable thread message truncation.** New `maxThreadMessageChars` setting (200-20000, default 800) controls how many characters are preserved per captured thread message. Higher values keep more context in long conversations. Configurable via dashboard, config file, or `NMEM_MAX_THREAD_MESSAGE_CHARS` env var. Contributed by @blessonism.
