- bugfix: 95_Astro: v2.0.2: Calculate astronomical season based on ecliptic
|
||||
latitude instead of static day of the year to make season
|
||||
transition times more reliable. Also, seasons for
|
||||
southern hemisphere are now reflected correctly.
|
||||
- change: 49_SSCam: Presets and Patrols can contain spaces in its name if the
|
||||
Preset or Patrol was definined in SVS or Cam Webinterface
|
||||
- bugfix: 74_AMADDevice: fix PERL WARNING: Subroutine redefined
