…ndary equality, verified against TradingView logs matrix.mult(vector) - Now returns PineArrayObject instead of PineMatrixObject, fixing polyline indicators like Spline Quantile Regression plotchar signature - Added PLOTCHAR_SIGNATURE with char parameter in correct position TYPE_CHECK.color - Now accepts Series-wrapped color values, fixing color loss when colors come from variables color.new/color.rgb - NaN transparency guard prevents invalid color strings like #787b86NAN00
Fix : properly serialize drawing objects to prevent cirtular references in context.plot

[0.9.8] - 2026-03-27 - TA Cross/CrossUnder, Matrix·Vector, Plot Serialization & Input Fixes
Fixed
ta.crossover/ta.crossunder: Boundary comparison now uses inclusive<=/>=where TradingView expects equality at the crossing bar (replaces strict</>). Verified against TradingView reference logs.matrix.mult(vector operand): Multiplying a matrix by a row/column vector now returns aPineArrayObjectinstead of aPineMatrixObject, matching Pine Script semantics and fixing polyline-style indicators (e.g. Spline Quantile Regression).plotcharSignature: CorrectedPLOTCHAR_SIGNATUREso thecharargument is in the proper parameter slot for dynamicplotcharcalls.TYPE_CHECK.color: Accepts Series-wrapped color values so colors passed through variables are not rejected and lost at runtime.color.new/color.rgb: NaN / invalid transparency no longer produces malformed hex strings (e.g.#787b86NAN00).input: Fixed bool input default/coercion edge cases.context.plot: Plot serialization avoids circular references when drawing objects are present.
