+Changelog for Makefile.pdlibbuilder.
+
+v0.6.0, dated 2019-12-21

+Fixes and improvements for Windows builds:
+- properly evaluate variables 'PDDIR' and 'PDBINDIR' to find pd.dll

+- strip installed Windows binaries by default
+(issues #34, #39, #41, #42 respectively)
+Warning for all platforms: variable 'PD_PATH' is no longer supported, use the
+equivalent 'PDDIR'.
