I have uploaded mintty 3.3.0 with the following changes:

Highlights
   * Screen dump as image (.png format), configurable file name and 
location.
   * Tektronix 4014 vector graphics mode.

Vector graphics
   * Tektronix 4014 terminal vector graphics terminal emulation (#896).

   * Cancel compose key on mouse actions, to prevent surprising 
character composition.
   * Fixed special key assignment (Ctrl+Shift+^) spoiled by KeyFunctions 
(since 2.9.1).

AltGrIsAlsoAlt prevention (since 3.1.5).

   * Fixed key modifier matching for KeyFunctions in some cases of 
Super/Hyper.
   * Dropped Ctrl+Enter special key assignments.
   * Deprecated Shift+Escape/Break/Pause.

(mintty/wsltty#238).
   * Handle proper link attributes when screen is scrolled (#1021).
   * Image saving feature for terminal contents (png format), DEC and Tek.
   * Fixed Shift+Alt+F2 size control on maximised/fullscreen windows (#633).

2.4.3).

Configuration
