Changes in version 2.2.0

download.c:
===========

Made the comparisons for possible download case insensitive

Added a check so that downloaded files, whose size has changed since last
download, will be downloaded again

pb.c:
=====

Suppressed the 'unknown tag' error message by suppressing sending of empty LOG and
FILES messages.

Changes some sprintf to snprintf on the suggestion of John, EI7IG

Skip the newly introduced parameter PREDICT_SERVER in pb.conf when scanning
for parameters in the configuration file.

Also log 'pygmies' ('runts')

Moved the filter in ProcessFrame so that all frames received are logged
in the KISS file

pb.conf:
=======
Added AO-51 to the list of known satellites

Added the default definition for PREDICT_SERVER (localhost)

pbctrl.c:
========

Cosmetic change (trailing blanks)

Removed the attempt to display the degree character in the el/az display

Changed the format for display of az and ele

pg.c:
====

Added a line to ignore the PREDICT_SERVER parameter in pb.conf

Added some comments

predict-client.c
================

Introduced a more robust predict client, courtesy Peter Scott, OZ2ABA. It
uses time-out so a non-responding server or lost packets will not cause
the program to hang - or appear hanged.

Also added a parameter to pb.conf that defines the Predict server. Default
is 'localhost'

Added code to make predict_client IPv6 (and IPv4) capable. Courtesy John 
Ronan, EI7IG.
