Trivia

• This is the second Microsoft Agent beta build to be confirmed by metadata, the first being Microsoft Agent 1.6.
• The existence of this build likely confirms that Microsoft Agent 1.1, 1.2, 1.8, and 1.9 potentially exist.
  • Based on version numbers, it was likely that Agent 1.1 is Microsoft Agent Beta and Agent 1.2 is Microsoft Agent Beta 2.0 as Microsoft Agent 1.3 is confirmed to Beta 3. However, on December 10th, 2025, screenshots of Microsoft Agent Beta 2.0 were found showing it has a version number of 0.2.0, and on December 22nd, 2025, Microsoft Agent Beta was found and had a version number of 0.11.
    • This proves 1.1 and 1.2 were not Beta and Beta 2, but instead are probably betas of 1.3.
