TPE for Desktop (Legacy Adobe AIR app): Release Notes

Version history

1.1.2 (July 12 2014)

Changes:

  • Adds notice regarding software end of life
  • Adds link to replacement web app
  • Permits export of locations even if map has not initialized

Installation:

  • Automatic update will fail, due to a certificate mismatch
  • To install, uninstall your current version (re-run the .air installer file and choose uninstall)
  • Download the 1.1.2 update here: http://ephemer.is/desktop-1-1-2
  • Double-click tpe_1_1_2.air to manually install the new version
  • Your saved locations are unaffected by uninstalling your current version, but if in doubt, export to KML first

1.1.1 (December 23 2011)

New features:

  • Secondary map pin can be positioned at a saved location (use Alt/Option + Go or Alt/Option + double click on saved location coordinates)
  • Primary map pin coordinates are now shown in a suitable format to paste directly into other applications (e.g. Google Maps) when selected

Changes:

  • Double clicking the map no longer recentres the primary pin, for consistency with TPE for mobile apps. You can still recentre the pin by pressing C on the keyboard.
  • Secondary pin does not reposition on change of primary position as long as it remains visible on the map

Fixes

  • Secondary elevation queries used AsterGDEM in preference to SRTM: set back to use SRTM as first choice source
  • Moon phase event timing could be incorrect by 30 minutes in areas with timezones that are fractions of hours (e.g. India, +5.5 hours)
  • Typos in glossary and tool tips

1.1.0 (November 26 2011)

New features:

  • Export selected locations to KML (for use in other programs, e.g. Google Earth)
  • Import locations from KML (e.g. placemarks generated using Google Earth)
  • Waxing crescent moon data now shows best observation time

Changes:

  • “Interesting” days logic improved to reduce false negatives

Fixes:

  • Timezone database for Europe and Russia updated
  • Program starts set to today for local system timezone (was UTC)

1.0.6 (June 5 2011)

Fixes:

  • Extended azimuth lines would shift slightly in 1.0.5 – fixed here (thanks to Steven Christenson)
  • Azimuth lines drawn as geodesics again (was broken in 1.0.5)
  • Some dates/locations would draw incorrect sun azimuth lines (e.g Svalbard, April 14 2010)

Changes:

  • Moon information now includes waning/waxing crescent/gibbous description
  • Waxing crescent moon visibility now calculated and displayed
  • “Interesting” moon days now excludes dates when new moon is not visible
  • Secondary marker drawn in higher contrast on satellite/hybrid map types

1.0.5 (January 21 2011)

Changes:

  • Updates GeoNames web services to use updated URLs
  • Improved handling of GeoNames web service errors and performance degradation
  • Terms of use and copyright notice updated

1.0.4 (December 20 2009)

New features:

  • Potentially “interesting” days for photos with the moon are denoted with an asterisk
  • In Details View, shadow length is now indicated

Fixes:

  • The colour of lunar azimuth lines would occasionally misbehave for southern hemisphere locations (thanks to Mark Moore)

1.0.3 (November 16 2009)

Fixes:

  • 1.0.2 would hang on startup for a clean install. Previous versions were not affected
  • Locations could not be created or saved for clean installs. Unsure which version introduced this defect.

1.0.2 (November 14 2009)

Changes:

  • Netbook users: TPE will now fit in screens with 600px resolution
  • Selected date format changed to an international format
  • “Reset to today” button added
  • Window size and state is now restored on start-up

Fixes:

  • Program would previously only detect one moon phase event per month – on occasions there are two (e.g. Full moons in December 2009)

1.0.1 (November 2 2009)

Changes:

  • Details view azimuth lines extend to 200 miles length on holding down Shift key
  • Timezone name tooltip modified to clarify that displayed timezone abbreviation is for midnight on the selected date

Fixes:

  • Program would hang on selecting date/location for which no moon phase event (e.g. Full Moon) occurred (e.g. any date in Feb 2010 in Sydney, Australia)
  • Timezone abbreviation was displayed for last calculated date, which could be different to that of actual selected date
  • On dates with daylight saving or other timezone offset adjustments, Details view altitude graphs were out of synch with displayed event times
  • On dates with daylight saving or other timezone offset adjustments, Details view events panel did not reflect adjusted time on moving slider
  • In the Configure panel, the Reset button was positioned incorrectly

My thanks to Jeff Conrad, Steve Carter, Andy Kubbat and Bruce Moss for their help in tracking these down.

1.0.0 (October 11 2009)

New features:

  • Plain text notes can be entered for any saved Location
  • Primary elevation above sea level can be selected and copied to the clipboard

Changes:

  • Auto-switch views checkbox has moved from Locations to Configuration
  • If Lock button is released programmatically (e.g. when swapping markers) it flashes briefly
  • When waiting for secondary marker elevation data, current data is dimmed rather than cleared (to match behaviour of primary marker)
  • Pre-sunrise/post-sunset azimuth extension lines drawn wider for improved visibility

Fixes:

  • Scroll bars would previously appear if distance from primary to secondary marker was too large to be displayed
  • Distance to horizon was previously displayed at times when primary marker was lower in elevation than horizon – it is now only displayed when marker lies at higher elevation
  • Variable length of detail view azimuth lines was broken in 1.0 RC1 – fixed here
  • Timezone change icon was not displayed for GMT locations (e.g. London on Sunday 25th October 2009)
  • Timezone change icon was incorrectly displayed for some locations (e.g. Moscow on Sunday 25th October 2009)

New features:

  • Location list can be dynamically filtered
  • Map coordinates are displayed to 4 decimal places
  • Map coordinates can be selected and copied to the clipboard (e.g. to paste into Google Earth)

  • Distance to horizon warning is only displayed if user has specified elevation at horizon and distance from primary to secondary is greater than implied distance to horizon
  • All azimuth lines are drawn to 200 miles length

Fixes:

  • Too many days were displayed at certain window sizes leading to overlapping controls
  • Clicking the Search label displayed the Horizon glossary entry

  • Use secondary map marker to set elevation at the horizon, or specify manually (to calculate dip of the horizon)
  • View the estimated distance to the horizon on the map, based on height above the horizon
  • Swap primary and secondary map marker positions using button or keyboard shortcut (S)
