v0.5.1 Release Notes

This patch release tightens MCP patch operation constraints and updates documentation for backend behavior clarity.

Highlights

• Added a service-level guard for backend-only op mixing:
• create_chart and apply_table_style can no longer be combined in a single request.
• Updated MCP docs and README pages for create_chart constraints:
• COM-only behavior
• supported chart types: line, column, bar, area, pie, doughnut, scatter, radar
• chart type aliases: column_clustered -> column, bar_clustered -> bar, xy_scatter -> scatter, donut -> doughnut
• related flag limitations
• incompatibility with apply_table_style in one request

Notes

• This is a compatibility and correctness-focused patch release with no new public tool surface added.
