**Announcing CipeXpatch 1.5.4-1.10 (stable)**
CipeXpatch 1.5.4-1.10 (stable) is available for download.

Information is available at:
http://www.hsx.dds.nl/software/cipexpatch/cipexpatch.html

Patch set is available at:
http://www.hsx.dds.nl/software/cipexpatch/cipexpatch-1.5.4-1.10.tar.gz
http://www.hsx.dds.nl/software/cipexpatch/cipexpatch-1.5.4-1.10.md5
Already patched version of CIPE:

Note: if you experience problems downloading the files using a WGET 
based downloader behind a NATed GW or proxy, use PROZ(ILLA) instead!

What's new:
===========
1. PKCIPE is supported as pkcipex; there are no functional differences 
with pkcipe, except that it works with cixed-cb.

2. A new parameter 'minratio' allows you to specify (as a percentage) 
the minimum compression ratio for which packets are sent compressed. 
I.e., if you specify 'minratio=105', packets with a compression 
ratio < 1.05 are sent uncompressed, saving the CPU-time to expand 
these packets at the peer. Slow CPUs on fast links will benefit.

3. Byte and packet counters are 64 bits. Statistics output is now 64 
bit unsigned long long for kernels >= 2.4.19 and unsigned long for 
older kernels. The byte counts are now also displayed in MBytes.

Attached is a file with results of best/worst case tests using FTP.

Enjoy,
