The preview announcement messages in the AutoRest README.md have inconsistent formatting with unnecessary escaping. The messages use "\r\n" for line breaks and have trailing spaces in some lines. These escape sequences may not render correctly when displayed to users. Consider using simpler formatting or ensuring consistent spacing across all preview messages.

The PreviewMessage attribute has inconsistent formatting across multiple custom cmdlet files. The message uses backticks with `n for newlines and has inconsistent spacing in the asterisk borders. Some lines have trailing spaces after asterisks, creating visual inconsistency. Consider standardizing the formatting to ensure consistent display across all cmdlets with breaking change announcements.

The ChangeLog entry violates the repository's custom coding guideline for ChangeLog.md files. According to the guidelines, changelog entries should be written from the user's perspective and explain what changed and how it affects their usage. The current entry "Preannounced breaking changes. Please refer to https://go.microsoft.com/fwlink/?linkid=2333229" is too generic and doesn't provide specific information about what breaking changes users should expect. Consider expanding this to briefly describe the nature of the breaking changes or at least mention which cmdlets or parameters are affected.
