-23.2 [2023-07-02]
-The Stellarium Team has released version 23.2.
-
-The major changes of this version:
-- vectorize marker of deep-sky objects
-- updated support locations
-- discovery circumstances for solar system objects
-
-Behind the scenes, many more minor issues were fixed.
-
-TELESCOPE USERS
-
-Like in the 1.* series, it seems the TelescopeControl plugin at least on
-Windows works better in the Qt5-based releases. Just install this if you
-are affected. We are looking for telescope users with programming skills
-to help us fixing this issue. Reward possible!
-
-23.1 [2023-03-27]
-The Stellarium Team has released version 23.1.
-
-From now on, releases will have version numbers indicating a year.release 
-scheme. For Windows, the version of the Qt framework used is visible as part 
-of the package name. Details are in the User Guide.
-
-PLEASE UPDATE!
-
-This issue mitigates a potential security issue (reported as CVE-2023-28371), 
-where scripts were allowed to write output text and screenshots to other places 
-on users' systems apart from the Stellarium user data directory or configured 
-screenshot directory. Running unknown scripts (which is a Bad Idea(tm) to begin 
-with) could have exploited that by attackers (script authors) writing even 
-command files to vulnerable places. We have not received a report where this
-would have caused a problem.
-
-However, now users must explicitly allow such behaviour in the settings
-tab of the Script Console.
-
-Apart from that, this release mostly aimed at fixing issues in the 1.*
-series, but also brought a few new features:
-- Much improved "Solar System observer" and other "Planet observers".
-- Solar dates along the ecliptic
-- Fixed issues with Observation Lists, and removed need for the extra
-  edit dialog.
-- Updated shader code for smoother projection
-- Allow texture decimation on the fly for very weak systems like
-  Raspberry Pi 3.
-- Solar limb darkening
-- Proper shadow edge for satellites
-
-Behind the scenes, many more minor issues were fixed.

-1.2 [2022-12-25]
-The Stellarium Team has released version 1.2.
-
-This release mostly aimed at fixing issues but also brought a few new features:
-- New projection: Equirectangular (fills the screen)
-- Improved rendering of Milky Way, Zodiacal Light and landscapes
-- Improved rendering of the Moon
-- Improved HiDPI behaviour
-- Use Noto as default font
-- Added Modern (IAU), Tikuna and Seri sky cultures
-- Added Chinese and Bahai calendars (Calendars plugin)
-

-
-1.0 [2022-10-01]
-The Stellarium team did it. Stellarium 1.0 is here!
-
-What makes this 1.0?
-
-- After more than 20 years of development the program is finally accurate 
-  enough for historical application.
-- This is the first release based on the Qt6 framework, so the project is 
-  safe for future development. These packages are tagged with a version 
-  number like 1.22.3.
-- We keep releasing Qt5-based packages for legacy or obsolete systems. 
-  This may include many Windows users who have to run ANGLE mode.
-  These packages are tagged with a version number like 0.22.3.
-
-What is new for users?
-
-- A new, much better skylight model (Not for MacOS and OpenGL ES2 systems, 
-  sorry.)
-- Many details around eclipses
-- Updated Observation List features
-- New features in AstroCalc tool
-- HiDPI improvements
-- Better dithering
-- Able to use Windows location service (Windows)
-- New skyculture: Samoan
-- Updated several skycultures
-- Updates in Angle Measure, Satellites, Oculars, Remote Control, Pulsars 
-  plugins
-- Many more bugfixes.
-
-A huge thanks to the people who helped us a lot by reporting bugs, and
-especially contributed in development!
-
-Clear Skies!

-0.15.0 [2016-07-31]
-In memory of our team member Barry Gerdes.
-
-Version 0.15.0 is based on Qt5.6. Starting with this version, some graphics cards 
-have been blacklisted by Qt and are automatically forced to use ANGLE on Windows. 
-We introduce a major internal change with the StelProperty system. 
-This allows simpler access to internal variables and therefore more ways of operation. 
-Most notably this version introduces an alternative control option via RemoteControl, 
-a new webserver interface plugin. 
-We also introduce another milestone towards providing better astronomical accuracy for 
-historical applications: experimental support of getting planetary positions from JPL DE430 and 
-  DE431 ephemerides. This feature is however not fully tested yet. 
-

-0.14.0 [2015-10-24]
-A big leap forward in astronomical accuracy for historical applications:
- - Precession now follows the IAU2006 model in the long-time version from Vondrak 
-   et al. 2011.
- - Nutation is applied (IAU2000B solution). Given that nobody has observed it without 
-   telescope and the model does not give limits of applicability, we limit its application 
-   to 1500..2500
- - Application of DeltaT has been simplified and made a bit more intuitive.
-
-We now dare to add another coordinate system: Ecliptic coordinates of date.
-
-We can therefore now show that planetary positions given by the commonly used solution 
-VSOP87 is applicable to -4000..+8000 only, and its use outside this range will give 
-somewhat artificial results. There is more to follow in future versions.
-
-The other big addition is a greatly improved collection of DSO data with lots of 
-possibilities in a new GUI tab to select for object type and/or catalog. In total, 
-15 catalogs are now built-in!
-
-Also the Meteor Shower, Satellites, Telescope Control and 3D Sceneries plugins have 
-been improved.
-
-Landscapes can have switchable labels, so you can e.g. indicate mountain peaks.
-
-In total 83 bugs and wishlist items were fixed or at least decided.
-
-A platform-specific change for Windows: OpenGL binding is now dynamic. That means, there are 
-no more separate OpenGL/ANGLE/MESA downloads, but after installation you will have separate 
-commands in the start menu which force ANGLE or MESA modes.

+23.3 [2023-09-25]
+The Stellarium Team has released version 23.3.
+
+The major changes of this version:
+- New plugin: Missing Stars
+- Allow semitransparent landscapes
+- Added discovery circumstances for Solar system bodies
+- Improve orbit drawing for minor bodies
+- Show named impact features as ellipses
+- Major changes in Navigational Stars plugin
+- Observing List fixes
+- Unambiguous comet names
+
+Behind the scenes, many more minor issues were fixed.
+
+TELESCOPE USERS
+
+We have identified and fixed some bugs in the TelescopeControl plugin on
+the Qt6-based releases.
+
+Telescope users, please try whether this solves your problems.
+If not, we are looking for those of you with programming skills to help
+us fixing remaining issues. Reward possible!
+
+23.2 [2023-07-02]
+The Stellarium Team has released version 23.2.
+
+The major changes of this version:
+- vectorize marker of deep-sky objects
+- updated support locations
+- discovery circumstances for solar system objects
+
+Behind the scenes, many more minor issues were fixed.
+
+TELESCOPE USERS
+
+Like in the 1.* series, it seems the TelescopeControl plugin at least on
+Windows works better in the Qt5-based releases. Just install this if you
+are affected. We are looking for telescope users with programming skills
+to help us fixing this issue. Reward possible!
+
+23.1 [2023-03-27]
+The Stellarium Team has released version 23.1.
+
+From now on, releases will have version numbers indicating a year.release 
+scheme. For Windows, the version of the Qt framework used is visible as part 
+of the package name. Details are in the User Guide.
+
+PLEASE UPDATE!
+
+This issue mitigates a potential security issue (reported as CVE-2023-28371), 
+where scripts were allowed to write output text and screenshots to other places 
+on users' systems apart from the Stellarium user data directory or configured 
+screenshot directory. Running unknown scripts (which is a Bad Idea(tm) to begin 
+with) could have exploited that by attackers (script authors) writing even 
+command files to vulnerable places. We have not received a report where this
+would have caused a problem.
+
+However, now users must explicitly allow such behaviour in the settings
+tab of the Script Console.
+
+Apart from that, this release mostly aimed at fixing issues in the 1.*
+series, but also brought a few new features:
+- Much improved "Solar System observer" and other "Planet observers".
+- Solar dates along the ecliptic
+- Fixed issues with Observation Lists, and removed need for the extra
+  edit dialog.
+- Updated shader code for smoother projection
+- Allow texture decimation on the fly for very weak systems like
+  Raspberry Pi 3.
+- Solar limb darkening
+- Proper shadow edge for satellites
+
+Behind the scenes, many more minor issues were fixed.
+
+TELESCOPE USERS
+
+Like in the 1.* series, it seems the TelescopeControl plugin at least on
+Windows works better in the Qt5-based releases. Just install this if you
+are affected. We are looking for telescope users with programming skills
+to help us fixing this issue. Reward possible!
+

+0.15.0 [2016-07-31]
+In memory of our team member Barry Gerdes.
+
+Version 0.15.0 is based on Qt5.6. Starting with this version, some graphics cards 
+have been blacklisted by Qt and are automatically forced to use ANGLE on Windows. 
+We introduce a major internal change with the StelProperty system. 
+This allows simpler access to internal variables and therefore more ways of operation. 
+Most notably this version introduces an alternative control option via RemoteControl, 
+a new webserver interface plugin. 
+We also introduce another milestone towards providing better astronomical accuracy for 
+historical applications: experimental support of getting planetary positions from JPL DE430 and 
+  DE431 ephemerides. This feature is however not fully tested yet. 
+
+- Added StelProperty system
+- Added new plugin for exhibitions and planetariums - Remote Control
+- Added new skycultures: Macedonian, Ojibwe, Dakota/Lakota/Nakota, 
+  Kamilaroi/Euahlayi
+- Updated code of plugins
+- Added Bookmarks tool and updated AstroCalc tool
+- Added new functions for Scripting Engine and new scripts
+- Added Miller Cylindrical Projection
+- Added updates and improvements in DSO and star catalogues (include initial 
+  support of The Washington Double Star Catalog)
+- azimuth lines (also targetting geographic locations) in ArchaeoLines plugin	
+- Many fixes and improvements...
+
+In addition, we prepared a new user guide.

+
+0.14.0 [2015-10-24]
+A big leap forward in astronomical accuracy for historical applications:
+ - Precession now follows the IAU2006 model in the long-time version from Vondrak 
+   et al. 2011.
+ - Nutation is applied (IAU2000B solution). Given that nobody has observed it without 
+   telescope and the model does not give limits of applicability, we limit its application 
+   to 1500..2500
+ - Application of DeltaT has been simplified and made a bit more intuitive.
+
+We now dare to add another coordinate system: Ecliptic coordinates of date.
+
+We can therefore now show that planetary positions given by the commonly used solution 
+VSOP87 is applicable to -4000..+8000 only, and its use outside this range will give 
+somewhat artificial results. There is more to follow in future versions.
+
+The other big addition is a greatly improved collection of DSO data with lots of 
+possibilities in a new GUI tab to select for object type and/or catalog. In total, 
+15 catalogs are now built-in!
+
+Also the Meteor Shower, Satellites, Telescope Control and 3D Sceneries plugins have 
+been improved.
+
+Landscapes can have switchable labels, so you can e.g. indicate mountain peaks.
+
+In total 83 bugs and wishlist items were fixed or at least decided.
+
+A platform-specific change for Windows: OpenGL binding is now dynamic. That means, there are 
+no more separate OpenGL/ANGLE/MESA downloads, but after installation you will have separate 
+commands in the start menu which force ANGLE or MESA modes.

+
+0.3.3 [Before] :
+I succed to compile my program in linux and windows with the same sources files !
+I decided to share my source code in GPL.
+My code was yet free but not very "readable" so i will try to comment it in english, and to make a version file (this file) etc... I now have to read docs to produce a "standard GNU code"...
