+## [v0.4.6](https://github.com/gusbrs/zref-clever/compare/v0.4.5...v0.4.6) (2024-08-23)
+
+### Fixed
+- Fix sorting of appendix references.

+### Changed
+- The `counterresetters` option now receives a full comma separated list of
+ counters as value, instead of working by incrementally adding values to the
+ list.

+% which are potential ``enclosing counters'' for other counters.
+%
+% Note that, as far as \LaTeX{} is concerned, a given counter can be reset by
+% \emph{any number of counters}. \cs{counterwithin} just adds a new
+% ``within-counter'' for ``counter'' without removing any other existing ones.
+% However, the data structure of \pkg{zref-clever} can only account for
+% \emph{one} enclosing counter. In a way, this is hard to circumvent, because
+% the underlying counter reset behavior works ``top-down'', but when looking
+% to a label built from a given counter we need to infer the enclosing
+% counters ``bottom-up''. As a result, the reset chain we find is path
+% dependent or, more formally, what \cs{@@_counter_reset_by:n} returns depends
+% on the order in which it searches the list of
+% \cs{l_@@_counter_resetters_seq}, since it stops on the first match. This
+% representation mismatch should not be a problem in most cases. But one
+% should be aware of the limits it imposes.
+%
+% Consider the following case: the \cls{book} class sets, by default
+% \texttt{figure} and \texttt{table} counters to be reset every
+% \texttt{chapter}, \texttt{section} is also reset every \texttt{chapter}, of
+% course. Suppose now we say
+% \cs{counterwithin}\texttt{\{figure\}\{section\}}. Technically,
+% \texttt{figure} is being reset every \texttt{section} and every
+% \texttt{chapter}, but since \texttt{section} is also reset every
+% \texttt{chapter}, the original ``\texttt{chapter} resets \texttt{figure}''
+% behavior is now redundant. Innocuous, but is still there. Now, suppose we
+% want to find which counter is resetting \texttt{figure} using
+% \cs{@@_counter_reset_by:n}. If \texttt{chapter} comes before
+% \texttt{section} in \cs{l_@@_counter_resetters_seq}, \texttt{chapter} will
+% be returned, and that's not what we want. That's the reason
+% \opt{counterresetters} initial value goes bottom-up in the sectioning level,
+% since we'd expect the nesting of the reset chain to \emph{typically} work
+% top-down.
+%
+% If, despite all this, unexpected results still ensue, users can take care to
+% ``clean'' redundant resetting settings with \cs{counterwithout}. Besides,
+% users can already override, for any particular counter, the search done from
+% the set in \cs{l_@@_counter_resetters_seq} with the \opt{counterresetby}
+% option.
+%
+% For the above reasons, since order matters, the \opt{counterresetters}
+% option can only be set by the full list of counters. In other words, users
+% wanting to change this should take the initial value as their starting base.
+%
+% The \texttt{zc@enclcnt} \pkg{zref} property, not included by default in the
+% \texttt{main} property list, is provided for the purpose of easing the
+% debugging of counter reset chains. So, by adding
+% \cs{zref@addprop}\texttt{\{main\}\{zc@enclcnt\}} you can inspect what the
+% values in the \texttt{zc@enclval} property correspond to.

+% Note that this support comes at a little cost. \opt{showonlyrefs} works by
+% setting a special \cs{MT@newlabel} for each label referenced with
+% \cs{eqref}. Now, \cs{eqref} is a specialized reference command, only used
+% to refer to equations, so it sets \cs{MT@newlabel} unconditionally on the
+% first run. \cs{zcref}, on the other hand, is a general purpose reference
+% command, used to reference labels of any type. But we wouldn't want to set
+% \cs{MT@newlabel} indiscriminately for all referenced labels in the document,
+% so we need to test for its type. Alas, the label must exist before its type
+% can be tested, thus we cannot set \cs{MT@newlabel} on the first run, only on
+% the second. In sum, since \cs{eqref} requires 3 runs to work, \cs{zcref}
+% needs 4.
