Release v0.6.0 · TriasDev/tabular

0.6.0 (2026-10-05)

the concrete cursors (CsvCursor, XlsxCursor, OdsCursor, ArchiveCursor, GzipCursor) and CsvDialectDetector are internal, so TabularFile.Open is the only way to a cursor; every public type is in the TriasDev.Tabular namespace, the format options included; CsvCursorOptions.Dialect is replaced by the Delimiter, Encoding and Quote hints and CsvDialect is output-only; the writer reports its limits as TabularWriteException (write.too-many-rows, write.too-many-merges, write.too-many-styles) instead of TabularLimitException; row numbers are int on both sides (TabularExport returns ValueTask, AnalysisProgress.RowsRead is int); HorizontalAlignment is CellHorizontalAlignment, TabularWriter.Style is RegisterStyle, CellStyle.Number and Date are NumberFormat and DateFormat; NumberFormat.Parse and DateFormat.Parse throw FormatException; typed import fields come only from their factories; CursorDiagnostics has no public constructor.

an invalid value locates nothing, an unneeded one costs nothing, and the precheck does not block AllOrNothing for rows that import (547cc20)
