Re: LilyPond 2.23.6 released

[Hans Aikema]

Jonas,

My experience for my specific scenario with 2.23.6 is quite bad: it appears to 
have broken PNG transparency (Mac OS 11.6.3 on Intel Mac (MacBook Pro Late 2013 
and Mac Pro 2013).

Creating PNG images with transparency ‘white on transparent’ (for the purpose 
of putting the in Powerpoint for ‘white on black background presentation 
slides) works fine when using Lilypond macports build for 2.22.1

Using macports build for 2.23.6 gs breaks at an error on the first page. The 
temp PNG appears to be white-on-white-background-with-transparent-page.

Using the Guile 2.2 build from Github I get all the expected PNGs, the first 
page appears to be white-on-white-on-transparent-page (all is see is a white 
irregular block on a transparent background) , from the second page onward the 
output is green-on-white-on-transparent-page
