Version 1.1

Release Date: July 2021

TLE orbit calculations updated to latest code library.
Can now load TLE orbit data from new JSON, XML or CSV standard files promulgated by CCSDS and Celestrak. Note that currently the program simply converts data from these files to legacy TLE format before doing calculations. So it currently still has the same limitations as legacy TLE, such as date limits and NORAD ID number limits.
Improved error reporting when loading TLE files and calculating orbits.
New View Type shows a Zenith Plot with X-Y pointing angles marked.
New item in main window Tools Menu to "Set As Default Site", so user can set the default start-up earth station coordinates, instead of always starting at Sydney Australia.
New item in main window File Menu to "Load Horizon File", allows quicker selection of horizon file than using View-Options-ObstructionsTab-Browse (which is still available).
Web access to check for updates is improved to use secure https:.
Fixed bugs with loading some GPX and KML files.
Fixed bug in HTML and PDF reports in case site name labels contain '&' or '<' characters.
Fixed bug in time calculations may have caused weird plots around local DST time change.
Fixed bug in horizon plotting for northern hemisphere sites.
Fixed bug on View Options where Help button opened wrong help page.
Fixed bug where sometimes fonts didn't resize after window size change.
Added blank lines in Pointing Angles report files to clearly separate different passes of the satellite.
Updated code libraries to latest versions.
Various minor improvements to coding and window layout.
Windows XP no longer supported by this program.
