-- add: MIME type exclusion for output compression (zstd.output_compression_exclude_types)
-- add: explicit --enable-apcu / --disable-apcu config.m4 options
-- fix: in-tree builds with apcu
+- add: built-in list of uncompressible MIME types for transparent output compression
+- add: negation tokens (!) in zstd.output_compression_exclude_types to compress a MIME type even though it is in the built-in list
