Also Guile-PNG updated to work with Guile-SMC 0.6. The library uses Guile-ZLIB[2] to compress/decompress the PNG data. Also this is the third project of mine that uses Guile State Machine Compiler (Guile-SMC)[3]. * List of user-visible changes =2D-8<---------------cut here---------------start------------->8--- * Changes in version 0.4.0 (2023-05-01) ** Bugfix: Init =3Dposition=3D slot of =3D=3D to a =3D=3D= instance The =3Dposition=3D slot would be always initialized to a procedure instead = of a =3D=3D instance.
