Changes in version 1.0.3 - First release on CRAN. The package gives R the tok engine of release 1.0.3: reading, checking (diagnostics as a data frame, in English or Polish), formatting, BPMN 2.0 and SVG export, export of every file for Camunda 8, BPMN import, decision evaluation, simulation with the event log and the cases as data frames, XES event logs, the diagram in the viewer and the knitr engine tok for R Markdown and Quarto. - Every exported function has examples. - The package builds with Rust 1.88 or newer. - The engine of 1.0.2 added three warnings of the BPMN rules: W022 (a branch without a condition at an element that splits conditionally), W023 (a sequence flow that repeats another one) and W043 (a sequence flow from an element back to itself); tok_check() returns them like every other diagnostic. - The engine of 1.0.3 adds four more: W044 (an activity or event with several outgoing flows without conditions, an implicit split), W045 and W046 (a sub-process without its own start or end event) and W047 (an event with several triggers). Changes in version 1.0.2 - Released on R-universe with the engine of release 1.0.2. Changes in version 1.0.1 - Released on R-universe (https://tok-lang-bpm.r-universe.dev) with the engine of release 1.0.1.
