 ## Aligned options with naming convention
 
 In version 7 of the CLI for Microsoft 365, we have made updates to the options for certain commands, aligning with our naming convention. This includes renaming options to ensure consistency and improve the CLI experience. For example, the option `--environment` for the command `m365 pa app consent set` has been changed to `--environmentName`. These changes aim to make it easier for you to use the CLI.
