Because flake8 upgrade to 6.0. Flake8 6.0 does not support inline comments for any of the keys, so comments should be put in newline.
Use this to prevent ValueError: Error code '#' supplied to 'ignore' option does not match '^[A-Z]{1,3}[0-9]{0,3}$'

When pylint==2.11.1, it installs mccabe 0.6.1. flake8 also requires mccabe, and only 4.0.1 meet the version constraint.

  - pylint [required: ==2.11.1, installed: 2.11.1]
    - astroid [required: >=2.8.0,<2.9, installed: 2.8.6]

    - pyflakes [required: >=2.4.0,<2.5.0, installed: 2.4.0]

After upgrading PyLint 2.7, mccabe becomes [required: >=0.6,<0.8, installed: 0.7.0], and flake8 becomes 6.0.0.

When run azdev style, it uses pylintrc and .flake8 in CLI/Extension repo folder. If the files do not exist, it use cli.xxxx or ext.xxx in azdev config folder.
CLI's .flake8 is updated in Azure/azure-cli#25370.

This hint is shown in the invalid-name error message. For example:
demo/demo.py:19:0: C0103: Class name "aa" doesn't conform to '{invalid-classname-hint}' pattern ('[_]{0,2}[A-Z]{1}[A-Za-z0-9]{0,30}$' pattern) (invalid-name)

I've removed all xxx-hint settings. See Azure/azure-cli#26685 (comment) and #359 (comment)

I think this is a incompatibility introduced by pylint 2.14

Several occurrences of E0015: Unrecognized option found on the config file:
function-name-hint, variable-name-hint, const-name-hint, attr-name-hint, argument-name-hint, class-attribute-name-hint, inlinevar-name-hint, class-name-hint, module-name-hint, method-name-hint - This is where the incompatibility is: The old option names are rejected by pylint 2.14, and the new option names are rejected by older pylint versions.

After further investigation, these naming-style config can be removed.

  1. They are nearly the same as default value.
  2. invalid-name rule is disabled, these configurations make no sense.
  3. cli_pylintrc hardly take effect as CLI has its own pylintrc.

I've removed them in CLI.

This changes the semantics of the code. Better to confirm if it is required or works as expected.
