 ### Changes
 
+- Telegram: render blockquotes as native `<blockquote>` tags instead of stripping them. (#14608)
 - Version alignment: bump manifests and package versions to `2026.2.10`; keep `appcast.xml` unchanged until the next macOS release cut.
 - CLI: add `openclaw logs --local-time` to display log timestamps in local timezone. (#13818) Thanks @xialonglee.
 - Config: avoid redacting `maxTokens`-like fields during config snapshot redaction, preventing round-trip validation failures in `/config`. (#14006) Thanks @constansino.
