 - macOS Voice Wake: fix a crash in trigger trimming for CJK/Unicode transcripts by matching and slicing on original-string ranges instead of transformed-string indices. (#11052) Thanks @Flash-LHR.
 - Heartbeat: prevent scheduler silent-death races during runner reloads, preserve retry cooldown backoff under wake bursts, and prioritize user/action wake causes over interval/retry reasons when coalescing. (#15108) Thanks @joeykrug.
 - Exec/Allowlist: allow multiline heredoc bodies (`<<`, `<<-`) while keeping multiline non-heredoc shell commands blocked, so exec approval parsing permits heredoc input safely without allowing general newline command chaining. (#13811) Thanks @mcaxtr.
+- Docs/Mermaid: remove hardcoded Mermaid init theme blocks from four docs diagrams so dark mode inherits readable theme defaults. (#15157) Thanks @heytulsiprasad.
