-* Numerous bugs have been fixed (no doubt some have been introduced :-)
-Thanks to those who reported bugs in ppp-2.2.
+This package supports two packet compression methods: Deflate and
+BSD-Compress. Other compression methods which are in common use
+include Predictor, LZS, and MPPC. These methods are not supported for
+two reasons - they are patent-encumbered, and they cause some packets
+to expand slightly, which pppd doesn't currently allow for.
+BSD-Compress is also patent-encumbered (its inclusion in this package
+can be considered a historical anomaly :-) but it doesn't ever expand
+packets. Neither does Deflate, which uses the same algorithm as gzip.
