+# v0.28.0
+
+Adds a `language` option so non-English sessions stay in your language instead of drifting back to English, and fixes the `ctx_reduce` reminder so it reflects how much is actually reclaimable rather than just how close you are to compaction.
+
+## Features
+
+- **`language`: keep generated text in your language (#192).** All of Magic Context's generated prose (historian summaries, dreamer memories, primers, the sidekick) and its guidance was English-only, so long non-English sessions slowly drifted back toward English. Set a top-level `language` (for example `"language": "Türkçe"` or `"language": "Español"`) and Magic Context writes its prose in that language while keeping everything structural in English exactly as before: XML tags, JSON keys, the memory category names, tool names, code, file paths, and transcript markers. Memory migration is deliberately language-preserving: turning the option on does not translate memories you already have, it only changes the language of newly written text. The option is user-level only (a project config cannot set it), defaults to off, and when unset the output is byte-for-byte identical to previous versions.
+
+## Fixes
+
+- **The `ctx_reduce` reminder no longer jumps to "urgent" just because you are near compaction.** The reminder's severity multiplied the reclaimable share by a pressure term, and because of how that term was defined it effectively counted pressure twice and was unbounded past the execute threshold. The result: once a tool-heavy session approached compaction, the reminder escalated straight to its most urgent wording regardless of how much was actually reclaimable. Pressure is now a gate (the reminder only fires once you are genuinely close to compaction), and the level reflects the real reclaimable share: roughly a fifth of your live input being unreduced tool output is a gentle mention, around two fifths is firmer, and only a clear majority is urgent.
+
+- **The reminder no longer suggests dropping your todo list or trivially small outputs.** Its "you could drop these" hint picked the oldest tool outputs with no regard for kind or size, so it could point at your `todowrite` plan (never a useful drop) or at tiny control-plane calls (a 30-token status line) that reclaim nothing. It now skips `todowrite` and anything below a small token floor, surfacing only outputs whose removal actually frees meaningful space.
