- Added two new (small) supplements: Landolt UBVRI photometric standard stars in the magnitude range 11,5-16,0 and Miles stars with spectral data. 

- MS Windows version 3.3.3f, added to UCAC4 info the APASS B-V magnitude for estimating star color and the calculated star temperature and class.

- 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.

- Linux version 3.3.3j_FPC fixed some path problems for help file and selecting FITS directory. Adapted some windows for large font size. Issued Linux i386 version (32 bit)
- MS Windows version 3.3.3d3, fixed a font problem in Windows 7.

Linux version 3.3.3h_FPC repacked with correct permissions set for the non English .ini files. The non-english files where not accessible You could solve this manually by following command line:

New Catalan help file by Antoni Clavell  and updated Esperanto translation of the program  by Ramon Perera.
Windows version 3.3.3d2,  added some words to translations.
Linux version 3.3.3h_FPC, fixed a problem with the grid in mean equinox of date. Added some words for translation.

Windows version 3.3.3d,  Linux version 3.3.3g_FPC, fixed a problem that in rare case magnitude of stars was not given.
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.

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

 Linux version 3.3.3d_FPC adapted for new folder /opt/hnsky.

 Windows 3.3.3c, fixed a problem in the status as introduced inversion 3.3.3b.

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:

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.

2016-10-12,  HNSKY version 3.2.6b & Linux 3.331b, introduced the 290-9 and 290-5 star database format. Reduced file size again with 10%  and 17%. Each star in the Gaia or U16 databases takes around 5 bytes disk space. These database versions are compacter but there is no gain in speed. You could keep the older databases for time being. For technical details see the help file. Made the star plotting routine a little faster. Disabled the mouse find function for disabled deep sky database.

2016-10-4/6,  HNSKY version 3.2.5a & Linux 3.330 and new compacter format for the star databases without quality loss. TYC and TUC record size goes from 11 to 10 byte saving  9% space.

You could keep the old databases. For technical details see help file.

2016-10-2, GAIA native HNSKY database up to magnitude 17 contains 164 million Gaia stars. Note that Gaia DR1 is missing some stars so is less suitable  for star maps. HNSKY version 3.2.4b or Linux 3.328 required, just released today. Unpack in the program directory, typically c:\program files\hnsky

2016-10-2, HNSKY version 3.2.4b & Linux 3.328. For above Gaia 290 star database.

2016-9-26, issued a new version of the TUC star database up to magnitude 15. Contains 7 % more stars due to other magnitude selection.

2016-9-25, HNSKY version 3.2.4a & Linux 3.326.  Fixed a problem in reading U16 star database type 290 with 7 byte record size. 

2016-9-24, New, native HNSKY database up to magnitude 16 contains 113 million stars. A compilation of UCAC4 and Tycho-2. (RAR file of 437 mbytes). HNSKY version or Linux 3.325 required.  No Tycho-2 or UCAC4 indentifiers are available due to 7 byte record size. Instead an IAU style designation based on the position is used.

2016-9-22, HNSKY version 3.2.4 & Linux 3.325.    Introduced 7 byte record size in 290 database. 

2016-9-14, HNSKY version 3.2.3b, Gaia DR1 support using Vizier online database up to magnitude 20. Gaia proper motion implemented.

2016-9-2 Native HNSKY database up to magnitude 15 containing 36 million stars made form TYCHO-2 and UCAC4. Compressed in a RAR archive the size is 192 mbytes. It will only work with the latest version 3.2.3. of HNSKY since it is in the "290" format. Abbreviation in the program as TUC

2016-8-8 HNSKY for LINUX,  version 3.323, 7z  archive. (70 mbytes) or executable only for Linux and MS Windows ), 4 mbytes.  Just extract somewhere in your home folder. Executable is the file "hnsky" Remove the .d32 files manually. They are replaced by .290 files.

2016-08-08, update in star database .290 files. Now complete Tycho+UCAC4 up to magn 12.5. (290 files date 2016-8-8-23:58, 23:59)
2016-08-06, HNSKY version 3.2.3 with new .290 star file format. Installer will replace the d32 files with .290 files!  This star database format will be faster and allow larger star databases
