Added:
- Added a new standalone heading/line "Long context pricing" (appears in a later section, possibly as a subsection header).

Changed:
- In the item announcing the 1M token context window beta for Claude Opus 4.6, the phrase "Long context pricing applies to" was shortened to "applies to" (removing the reference to "Long context pricing").
- The bullet for the `computer_20250124` tool (listing its new command options) was moved from the February 10th, 2025 section to a later section; the content itself is unchanged.

Removed:
- Three bullet points from the May 21, 2025 release notes were removed:
  - "We've launched the Files API in public beta, enabling you to upload files and reference them in the Messages API and code execution tool."
  - "We've launched the Code execution tool in public beta, a tool that enables Claude to execute Python code in a secure, sandboxed environment."
  - "We've launched the MCP connector in public beta, a feature that allows you to connect to remote MCP servers directly from the Messages API."
