=== Release preparations === | |||
Following the [[release plan]], the FlightGear repositories will close for major changes on June 17. In this "frozen" state, no new features or major changes shall be pushed onto the development streams (neither source nor data). This period is for preparing the code for the release and make sure there are no major issues. It lasts for four weeks until creation of the release branches on July 17. | |||
It's a good idea for aircraft developers to adhere to this rule. However, aircraft in fgdata may be handled as an exception from the frozen state. Any change to aircraft may be pushed to the repository if it is guaranteed that this change does not affect any other aircraft or system and if no file outside the root directory of that specific aircraft is changed. Also, aircraft defined as part of the base package (e.g. the c172p) enter the frozen state and shall not undergo major changes in that period. | |||

=== Canvas | === Tutorial: Porting custom PUI widgets to Canvas === | ||
[[File:Nasal-console-with-canvas-loglist-widget-prototype.png|thumb|canvas based loglist widget]] | |||
The shortcomings of our old PUI-based GUI have been repeatedly brought up on the mailing list over the years. | |||
In order to eventually phase out PUI completely, we need to stop adding PUI dependencies to the source tree. We now have the Canvas system, and there's a formal decision to modernize the GUI using the Canvas, and completely replace PUI sooner rather than later. | |||
It was a lot of work to get rid of hard-coded PUI dialogs, and we still have a bunch of hard-coded PUI widgets – as long as we have those, getting totally rid of PUI will be increasingly difficult, because each hard-coded widget will either need to be phased out or manually ported. | |||
Which is exactly the reason why adding additional PUI widgets to the source tree is a really bad idea and counter-constructive to accomplish our long-term goal of phasing out PUI completely. | |||
This is why we now have a dedicated tutorial about porting our old custom PUI widgets to make use of the Canvas system: [[Canvas GUI]]. | |||
Core developers are requested not to add any new PUI widgets to the source tree, but instead help identify shortcomings of the existing Canvas/Nasal interface, so that it can be accordingly extended, in order to allow custom widgets to be specified outside C++ space - which can usually be quickly accomplished using the cppbind framework. | |||
=== Canvas System === | |||
If you have been wanting to play around with the new [[Canvas]] system, make sure to check out the [[Howto:Adding a canvas to a GUI dialog]] tutorial, which demonstrates how to easily add a canvas rendering region to a conventional FlightGear dialog. Using the combination of Nasal scripting, standard FlightGear GUI dialogs and embedded canvas regions for 2D rendering, you can even create standalone "FlightGear applications" in the form of self-contained FlightGear XML dialogs that you can easily share with fellow FlightGear users. | |||
=== | This can for example be used to create a plotting application like FGPlot (see below), which would look to FlightGear like a conventional dialog. | ||

We would like to emphasize that the monthly newsletter can not live without the contributions of FlightGear users and developers. Everyone with a wiki account (free to register) can edit the newsletter and every contribution is welcome. So if you know about any FlightGear related news or projects such as for example updated scenery or aircraft, please do feel invited to add such news to the newsletter. Core developers are encouraged to add news about their latest work to the newsletter's development section and the changelog of the upcoming release. At the end of each month, it's generally a good idea to get in touch with other contributors to ask them to add news about their contributions to the newsletter.

Clicking on the button executes the bindings, allowing the user to watch as the computer/co-pilot/instructor executes the checklist item.

Tutorial: Porting custom PUI widgets to Canvas

In order to eventually phase out PUI completely, we need to stop adding PUI dependencies to the source tree. We now have the Canvas system, and there's a formal decision to modernize the GUI using the Canvas, and completely replace PUI sooner rather than later.

If you have been wanting to play around with the new Canvas system, make sure to check out the Howto:Adding a canvas to a GUI dialog tutorial, which demonstrates how to easily add a canvas rendering region to a conventional FlightGear dialog.

Getting involved as a programmer
Unfortunately, most of the active FG developers are currently very overstretched in terms of the areas that they have ownership of, which is affecting how much can actually be done. Fundamentally we need more core devs.

Web tools for ATC sessions in Europe
Some new web tools help planning ATC events are in development. They was initiated by lenny64 who announced on the official forum on Apr 27, 2013 that he had the first version of a web site, lenny64.free.fr, that made it possible to see and plan ATC sessions at some of the airports in Europe. Since then it have become possible too file flights to some of them.
He later announced that similar functionality was added by evilslut to his tracker and mpserver, mpserver12.
These services makes it possible:
- To see planned and current ATC sessions at various airports
- To plan ATC sessions for those airports
- To file flightplans to at least some of those airports
- For ATCs to see what flightplans are filed to and from his airport
The airports currently supported by those services are (airports with asterisk are only supported by lenny64):
- Frankfurt am Main Airport (EDDF)
- Leipzig/Halle Airport (EDDP)
- Flughafen Stuttgart (EDDS) *
- London Gatwick Airport (EGGK)
- Luxembourg Findel Airport (ELLX)
- Marseille Provence Airport (LFML)
- Paris Orly Airport (LFPO) *
And finally ...
Contributing
One of the regular thoughts expressed on the FlightGear forums is "I'd like to contribute but I don't know how to program, and I don't have the time". Unfortunately, there is a common mis-conception that contributing requires programming and lots of free time. In fact, there are a huge range of ways to contribute to the project without needing to write code or spending days working on something.
For ideas on starting to contribute to FlightGear, you may want to check out: Volunteer.
To learn more about how the project works, please see this short essay written by Thorsten, for a more detailed article see How the FlightGear project works.
Call for volunteers
- The Flightgear On Android team is looking for testers
- The Target4Today team is looking for volunteers to help improving FlightGear's combat support
- The FGFSPM (FlightGear Package Manager) is looking for a new maintainer.
