2017-6-4,
- Linux version 3.3.3L_FPC (amd64 and i386) Fixed a major problem with mouse position detection (source code typo). Secondly a fix for the Linux version preventing application hanging if no internet connection available. For the Linux version the Skyview download link should be changed from http to https to make it working! In version 3.3.3L1 this is done automatically.

- MS Windows version 3.3.3e
- Linux version 3.3.3k_FPC (amd64 and i386)
Reintroduced midnight=24:00 hours as far as possible. I was not happy with the temporary 23:00 hours solution. The time input still doesn't allow 24:00 hours /12:00 PM and will show midnight as next day at 00:00 hours/12:00 AM. Since it is a standard module mirroring the operating system time format it can't be changed.
Fixed a problem with syntax check for supplements.

Added the Win10 Night light option to the night vision mode. Note this will only work if you have the latest Win10 updates and it will take 10 minutes to reach maximum red color shift. If switches off, Win10 will take 10 minutes to restore the normal colors.

2017-5-8,
 Linux version 3.3.3f_FPC, fixed in Settings menu the dropdown list of  non-English versions.

2017-5-4,  Windows version 3.3.3b, added CTRL+double mouse click for telescope pointing. 

2017-5-3,  Linux version 3.3.3b_FPC.  Fixed some path problems. Now released in a Debian package.

2017-4-29,  Linux version 3.3.3a_FPC Fixed some problem in the INDI interface. Works now reliable for remote control using  INDI and with drivers like LX90, LX200, Celestron.

2017-4-16,  very minor corrections in the help files.

2017-4-14,  HNSKY version 3.3.3. Added access to wide field DSS images from NAO.  This allows large fields up to 6  similar as Skyview. Example:


2017-4-12,  HNSKY version 3.3.2d and Linux version 3.3.2d_FPC, several minor corrections.

2017-4-9,  HNSKY version 3.3.2c and Linux version 3.3.2c_FPC. Some minor improvements. The Linux version is no longer . Will be identified with same version ending with FPC.

2017-4-7,  HNSKY version 3.3.2. Two new features for supplement manipulation and one could be be used to keep a logbook of observations :

Edit menu for a single supplement entry:
1) For convenience HNSKY provides and additional edit menu to access a single supplement entry. This could be used to add a log or an observation in the "type" field.  You could either use an existing supplement or add a new label at the mouse position (home key). Rename an existing supplement before you use it otherwise a new HNSKY version could overwrite it if updated.
See in the online help file:
www.hnsky.org/help/uk/hnsky.htm#suppl_edit

Import tool in the editor:
2) New option for creating a supplement from a text list of objects. I made this for personal use. If I copy my HTML based astro image web page and then paste it inside the editor, the program will process and create a list of labels with their corresponding position. All recognizable deep sky names will be recorded once and remainder will be ignored. This helps me personally to keep an updated record of deep sky objects images taken. Any textual list of deep sky object will be imported. Maybe useful for others.



2017-3-31,  Introduced Spanish help file. Excellent translation work by Roberto
2017-3-8,  HNSKY Linux version 3.342. Fixed a problem with the map clock.

2017-3-7 and 8,   Help file overhaul, Roberto made very nice new style. Thanks. Hope you like it.

2017-3-6, HNSKY version 3.3.1a/ 3.341 Updated the help file and non-English files.

2017-3-2, HNSKY version 3.3.1  Significant update:
- Added a modern date & time input and a monthly calender. The calendar doesn't allow dates beyond year 1752 and 9999 so there is still an traditional input.  The midnight button is now setting 23:00 hours. since 24:00 hours is not allowed in the current setup.

- Automatic daylight saving adjustment for time zones  in the setting menu
            USA:      PST/PDT, MST/MDT, CST/CDT, EST/EDT
            Europe:  GMT/BST CET/CEST
The daylight saving is based on the current valid rules and works from 1977 (arbitrary) to year 20.000+. No effort is made to follow historical  changes using a so called Time Zone Database. Using the function buttons F3, F4, F5, F6 it is possible to step through the daylight saving dates changes.

- Uses the decimal separator dot or comma as specified in your (Windows) system settings . However the dot as separator is always accepted.

Both the daylight saving and date & time menu took significant effort to implement. Please review and report any bug or problem.

Some work for the translation files is still required.
