+## What's New
+
+### New skills
+
+- **design-is** (#2483) — audits a design against Dieter Rams' ten "Good design is..." principles. Produces per-principle 0–3 scores with file:line evidence and a NEW / REFINE / REDESIGN verdict, then hands off a ready-to-run `/make-plan` prompt.
+- **weekly-digests** (#2399) — produces a chapter-per-ISO-week serial digest of a project's full claude-mem timeline. Sequential subagent pipeline keeps the narrative coherent across 30+ chapters.
+- **oh-my-issues** (#2409) — root-cause issue clustering. Codifies the consolidation method that turned ~100 open issues into 6 plan-masters during the v13.0.1 cycle. Three modes: cluster pass, triage, bundle.
+
+### Fixes
+
+- **fix(mcp): drop duplicate root `.mcp.json`** (#2411) — Claude Code's `/doctor` was warning "MCP server mcp-search skipped — same command/URL as already-configured mcp-search" for every plugin user. The root copy was vestigial; the plugin's namespaced registration now wins.
+- **fix: stop Codex transcript replay after hooks migration** (#2365) — disables the default `~/.codex/sessions/**/*.jsonl` watch (native Codex hooks are now authoritative). Repairs `~/.codex/config.toml` to set `[features] hooks = true` and `[plugins."claude-mem@claude-mem-local"] enabled = true` directly. Fixes transcript replay where files discovered after startup ignored `startAtEnd` and re-injected history.
+
+Opt back into legacy Codex transcript ingestion with `CLAUDE_MEM_CODEX_TRANSCRIPT_INGESTION=true` if you depend on the JSONL watcher.
