Just out of curiosity, is there any recommended way to parse out "which" 
parameter goes wrong. For example, we have "unknown_action" before. Now it gets 
merged into "badvalue", and the response looks like this:

{
    "error": {
        "code": "badvalue",
        "info": "Unrecognized value for parameter \"action\": test.",
        "*": "See https://test2.wikipedia.org/w/api.php for API usage. 
Subscribe to the mediawiki-api-announce mailing list at 
<https://lists.wikimedia.org/mailman/listinfo/mediawiki-api-announce> for 
notice of API deprecations and breaking changes."
    },
    "servedby": "mw1361"
}

Do I have to parse into .error.info content to know the parameter name? Would 
its content change (such as localized) under certain situation?

Thanks,
Xinyan

The error codes that may be changing are some of those representing invalid 
values for API parameters. Notably, the following will change:

   - "noX", indicating that a required parameter was not specified, becomes
   "missingparam".
   - "unknown_X", indicating that an unrecognized value was specified for
   an enumerated-value parameter, becomes "badvalue".
   - "too-many-X", indicating that too many values were supplied to a
   multi-valued parameter, becomes "toomanyvalues".
   - "baduser_X", "badtimestamp_X", and so on become "baduser",
   "badtimestamp", and so on.

Note this is not a comprehensive list, other codes may be changing as well.

These changes make the error codes more predictable, at the expense of not 
indicating in the code which parameter specifically triggered the error. If you 
have a use case where knowing which parameter triggered the error is needed, 
please let us know (by replying to this message or by filing a request in 
Phabricator) and we'll add the necessary error metadata.

The human-readable text is also changing for some of these errors (with or 
without error code changes), and for a few the error metadata may be changing 
(e.g. "botMax" changes to "highmax" for limit-type warnings in non-back-compat 
error formats).

This change will most likely go out to Wikimedia wikis with 1.35.0-wmf.19.
See https://www.mediawiki.org/wiki/MediaWiki_1.35/Roadmap for a schedule.

Various unusual values for integer-type parameters to the Action API will no 
longer be accepted. Acceptable values will consist of an optional sign (ASCII 
`+` or `-`) followed by 1 or more ASCII digits.

Values that were formerly allowed, and will now result in a "badinteger"
error, include:

   - Values with extraneous whitespace, such as " 1".
   - "1.9", formerly interpreted as "1".
   - "1e1", formerly interpreted as either "1" or "10" at various times.
   - "1foobar", formerly interpreted as "1"
   - "foobar", formerly interpreted as "0".

Most clients should already be using correct formats, unless they are taking 
direct user input without validation.

This change will most likely go out to Wikimedia wikis with 1.35.0-wmf.19.
See https://www.mediawiki.org/wiki/MediaWiki_1.35/Roadmap for a schedule.

For example * {{audio|en|en-us-dictionary.ogg|Audio (US, California)}}
