v3.2.11

Mercury 3.2.11 adds seven new widgets for dashboards, interactive examples,
browser media capture, and animated output.

New widgets

• mr.Camera — live camera preview with photo capture and short video recording.
  Captured media is available as bytes in Python.
  #605
• mr.Microphone — record and preview browser audio, then access the recording
  directly in Python. #606
• mr.Examples — populate multiple input widgets from predefined examples with
  a single click and notebook execution.
  #594
• mr.SplitFlap — animated retro split-flap display for counters, scores, and
  dashboard headlines. #600
• mr.VUMeter — animated analog meter for utilization, confidence, and
  performance values. #602
• mr.Teletype — character-by-character terminal-style text output with
  incremental appending. #603
• mr.StatusLights — compact animated status indicators for services,
  workflows, and monitoring dashboards.
  #604

Chat improvements

• Fixed Chat clearing existing output during construction.
• Improved automatic scrolling for fixed-height and parallel streaming chats.
• Scrolling upward now pauses auto-follow, allowing users to read earlier
  messages without being pulled back to the bottom.
• Multiple chats no longer compete for the page scrollbar.

Security

• Markdown generated by mr.Markdown and Markdown chat messages is now
  sanitized by default.
• Scripts, event handlers, unsafe URLs, and untrusted custom styles are removed.
• Trusted applications can explicitly enable raw HTML with
  unsafe_allow_html=True.

Documentation

Added documentation, tests, and showcase notebooks for all new widgets,
including camera capture, microphone recording, stock-price split-flap
displays, and predefined input examples.
