Release Notes

jmcnamara/rust_xlsxwriter (rust_xlsxwriter)

### [`v0.50.0`](https://togithub.com/jmcnamara/rust_xlsxwriter/blob/HEAD/CHANGELOG.md#0500---2023-10-12) [Compare Source](https://togithub.com/jmcnamara/rust_xlsxwriter/compare/v0.49.0...v0.50.0) ##### Added - Added support for chart trendlines (Linear, Polynomial, Moving Average, etc.) via the [`ChartTrendline`][ChartTrendline] struct and methods. - Added the [`worksheet.set_very_hidden()`][worksheet.set_very_hidden()] method to hide a worksheet similar to the \[`worksheet.set_hidden()`] method. The difference is that the worksheet can only be unhidden by VBA and cannot be unhidden in the the Excel user interface. - Added support for leader lines to non-Pie charts. ##### Fixed - Fixed handling of [future functions] in table formulas.
