Legislation type does not display suffix after year

[rolandog]

In the process of updating a Stack Exchange answer, I noticed that the legislation type didn't show a suffix for the second reference (the one using the legislation type), as can be seen that 2016b is not present in the citation:

Here's the code I used:

\maketitle

One could cite as \texttt{online} \parencite{GDPR2016a}, or as
\texttt{Legislation} \parencite{EuropeanParliament2016a};
however, the latter would only be available if the chosen citation
style has a driver for the \texttt{Legislation} type.

\printbibliography

Fixed in next release, thanks for reporting. To fix now, replace:

\newbibmacro*{statdate}{%
  \iffieldundef{origyear}
    {\printtext[parens]{\printlabeldate}}
    {\printtext[parens]{\printorigdate%
                        \addspace\&\addspace rev\adddot\addspace\printlabeldate}}}

with

\newbibmacro*{statdate}{%
  \iffieldundef{origyear}
    {\printtext[parens]{\printlabeldateextra}}
    {\printtext[parens]{\printorigdate%
                        \addspace\&\addspace rev\adddot\addspace\printlabeldateextra}}}
