James has pushed a large change to next, which adds a binary cache of most of  the navigation data. The cache is stored in FG_HOME/navdata.cache, and rebuilt if the timestamps on any of the data files change (apt.dat, nav.data, fix.dat and so on). When the cache needs to be rebuilt, startup will take a bit longer  than before, but when the cache is valid, startup is /much/ faster, especially for debug builds:
+
* Navigation data is cached and only rebuilt when you install new data. This results in lower memory consumption and faster startup.
 
  −
{{cquote|Memory consumption is also lower, since we don't keep airports / fixes /  taxiways / runways in memory until they're needed.
  −
 
  −
This is a fairly large change, so please look out for any bugs related to navaids / startup position / GPS / route-manager searches and lookups either getting different results or failing. I've tested here locally and things seem
  −
sane, and have had positive feedback from various testers on IRC and email, but I still expect to find some edge cases which need further work.
  −
 
  −
There's future work to move even more data into the cache - eg parking positions - which will further help performance for FMS / map systems since we won't need to parse lots of XML data repeatedly. I'm going to let this change settle down before adding more cached data, however.<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg38330.html |title=[Flightgear-devel] Nav-cache|author=James Turner |date=Wed, 19 Sep 2012}}</ref>}}

  −
* Random Buildings memory occupancy has been improved significantly, making this feature available to more users.

'''Project Rembrandt'''
  −
 
  −
Fred's been working on some fancy new effects, especially useful for our film-making enthusiasts.
  −
 
  −
The [[Project Rembrandt|Rembrandt renderer]] has a lot of potentiality when it comes to post processing effects. Indeed, the interesting property of a deferred shader is that all stages of rendering are kept into memory. Post-processing is as simple as using a filter on a camera.
  −
 
  −
So currently the effects added in git are :
  −
* Night vision including amplification grain and restrained field of view,
  −
* Cinema effect including :
  −
** Vignetting,
  −
** Color shift, with Sepia as default value,
  −
** Radial distortion (barrel and pincushion distortion, with scale compensation),
  −
** Lateral chromatic aberration (purple fringing),
  −
** Film wear simulation.

* The weather configuration GUIs have been combined and rationalized into a single Weather GUI, making it easier to select a nice VFR day, or a difficult CATIII approach.
