Unfortunately both major and minor were used causing version 20.1 to be incompatible with 20.0. This patch fixes the issue by switching from 2-part to 3-part ABI version numbers so that we can keep 20.0 as soname and using the final digits to identify the 20.x releases which are ABI compatible. This requires changes to both make and meson builds to handle the three-digit version and shrink it to 2-digit for soname.
