v1.5, 2025-02-24

New features

• Added support for LaTeXML including the key alt=<value> to define an alternative text representing a diagram for screen readers.
• Added references to a supporting online tool, the PrOSET editor.

Modifications and fixes

• The short hand macros \pcausetL, \pcausetP, \pcausetX, \rcausetL, \rcausetP, \rcausetX, \causetL, \causetP and \causetX are now depreciated. Write \pcauset[labeled], \pcauset[permutation], \pcauset[permutation, labeled], etc. instead, or use the PrOSET editor to design diagrams.
• Removed the short hand macros \causetFence and \causetCrown.
• Corrected typos in the manual.

v1.4, 2023-03-06

New features

• Second values in the sequence of the first argument: now modifies the style of individual events, the events are replaced with the key event=<value>, and the labels are set with label=<value>.
• Third values in the sequence of the second argument of \causet and \rcauset: to modify the style of individual links.
• Broken links for restyled links of \rcauset: restyled links can also be drawn between events that would have not been automatically linked, hence these links might now be broken up like the links of \causet.
• New key name=<value>: to define a name of a causet for easier readability of the tex source code (and to be used as external file name when the corresponding package option has been activated).
• New option external: to load the external library of TikZ for automatic externalisation of all diagrams.
• New key set prefix=<value>: to pass a file name prefix that is combined with a causet name for the external files when using external.
• New key name external=<bool>: to activate/deactivate using the causet names for external files.
• Main commands: padded by a thin space (adjustable with padding=<value>) for a better spacing in text and math mode.

Modifications and fixes

• Third values in the sequence of the first argument: no longer supported.
• Spatial links: are now drawn before (so on a lower layer than) links.
• Style arrow links: the arrow heads are now filled.
• Macro \causetspath: has been replaced by name prefix=<value>.
• Short-hand macro \causetCrown: changed to take a single argument (and the optional style argument) and returns the same output as \causetClosedFence used to, which has been removed.

v1.3.1, 2022-07-27

Modifications and fixes

• Automatic event labels: now correctly printed when using offset=<value>.

v1.3, 2022-05-23

New features

• Integer sequences in the arguments: use a permutation of an interval $[ a, b ]$, where $a$ and $b$ do no longer have to be natural numbers but can be any integers ($a \leq b$) including 0 and negative numbers. These numbers name and label the events of the causet if the respective options are chosen.
• Second values in the sequence of the first argument: to change the name and label of events.
• New key offset=<value> (0 by default): to define an integer shift for all events before they are named and labeled.
• New style text font=<value> (additionally to text scale=<value>): to adjust the font style of text (labels), for example, to set the font size to 20pt (and a baseline skip of 24pt), use text font=\fontsize{20}{24}\selectfont

Modifications and fixes

• Size options: all sizes are now scaled with respect to the normal size.
• Event style: line thickness of the event outline has been corrected.
• Size macros removed: \causetRegionLine, \causetGridLine, \causetEventSize, \causetLinkWidth, and \causetBrokenLinkGap. The respective values are now stored in PGF keys and are measured with respect to the size unit (stored in \causetTileSize).
• All package options: reduced to single words.
• Permutation for \*causetL...: now deactivated (if activated in the document before), by default.
• Labels for \*causetP...: now deactivated (if activated in the document before), by default.
