Since it has been broken since the move to git and is unlikely to
have been particularly useful anyway, I've just merged a change to
remove the version information (and the 'version' parameter) from the
API help. This may result in a warning about an unrecognized
Also, the 'version' property in the results from action=paraminfo will
now be the empty string. It was not removed completely at this time to
avoid breaking clients where accessing an undefined property is a
fatal error; however, it should be considered deprecated and may be
removed in a future version.
Note that version information for MediaWiki as a whole is still
available via prop=siteinfo.
: e.g. https://en.wikipedia.org/w/api.php?action=query&meta=siteinfo
For badcontinue errors, the API currently returns a code of either
"??badcontinue" or "??_badcontinue" (where ?? is the module's prefix),
depending on the module. The human-readable error message text may
also vary depending on the module.
In 1.21wmf8, these will be standardized as "??badcontinue", with a
human-readable message of "Invalid continue param. You should pass the
original value returned by the previous query".
Since well-behaved API clients should never see this error message,
this change should not require any client updates.
