I have uploaded mintty 2.6.1 with the following changes:
* Released Sixel graphics support in a stable version. With this nice
feature, you can embed graphics output in the terminal, for example with
* Tweaked DPI scaling to avoid terminal resizing on font selection
* Enabling auto-scaling of window decoration (#547, #517, thanks to
Jason Mansour #588).
* Option AllowSetSelection to enable OSC 52 control sequence to set
clipboard for pasting (#258, thanks to kangjianbin).
* Tweaked underscore cursor position, considering row spacing (#589).
* Retaining config file comments (#574).
