Track rpic 0.6.2 (the 2026-07 audit series): always-valid SVG for negative dimensions, canvas bounds that contain arrowheads and math fragments, dpic-parity fixes for chop/continue/dead for bodies, and structured eval-phase diagnostics with include attribution.
Internal: the option builder is resilient to additive engine option fields.
rpic 0.6.1
Track rpic 0.6.1 (rpic-core/rpic-render from crates.io; previously 0.1.0).
New texlabels argument on rpic_svg(), rpic_png(), rpic_pdf() and rpic_manifest(), and as a knitr chunk option: fully $...$-delimited labels are typeset as TeX math, natively (the math renderer is now registered — it previously was not, so math labels fell back to literal text).
circuits = TRUE is now a compile option instead of prepending the library to the source: compile-error positions stay relative to your own input. The library can also be loaded in-source with copy "circuits".
Structured errors: compile failures are raised as a classed rpic_error condition; e$info holds the diagnostic (message, line, col, end_col, file, kind, found, expected, hint).
rpic_manifest() bundles now include a warnings array with structured compiler warnings for accepted-but-ignored input.
