Changelog for v5.8.6:
Plane labels can be moved around freely, using the Shift key + left mouse button. This can be handy to avoid overlapping labels in busy areas. The default label position of all planes can also be adjusted using the Ctrl key + left mouse button. The keys can be customized in the Controls menu (press F7, see page 2 and 6). To reset the position back to default, simply press the Label button in the Display menu.
For custom airports:
All routes in an [approach] section are now available in-game by pressing the APP button multiple times. In earlier versions, just 1 route was selected (it would select the route which best matched the 'bearing' given for that route, meaning you could only choose 1 route per runway). Now all routes are available, sorted from best to worst bearing.
Approach routes can intercept the ILS as low as a height of 300 feet.
Departures on a route can resume their route, for example after a plane had been given a heading. Or it can get a shortcut to a waypoint further ahead on the route. This is only possible when the location of a certain waypoint of the route matches another defined beacon/sid point in the file. You can then drag a heading onto that waypoint, and SID mode will be enabled with the route continuing from that waypoint.
Fixed a bug where the custom maximum altitude of a plane on a departure route did not always apply (this is regarding the 'above' override feature for routes, that was introduced recently in v5.8.4 to allow for lateral handoffs).
Fixed incorrect drawing location of 'text' and 'label' in the [background] section. To make sure older custom airport files look unchanged, the corrected properties have been renamed to 'bgtext' and 'bglabel'.

Bug fixes:

Fix for the Alt key sometimes getting stuck after Alt-Tabbing.
Fix for key bindings sometimes not saving after changing them.
Adjustments:

All localizer ranges are extended by 2 miles, so the default range is now 25 miles from touchdown, similar to most runways in real life. It makes controlling slightly easier during busy hours.
The separation alarm will be inhibited when selecting the affected plane, even if that plane was already selected.
In the runways menu, the 'virtual score' setting no longer affects traffic rates of secondary airports. It only activates more runways.
Expanded the translations file.
Minor changes to handoff readbacks.
For custom airports:

Added 'localizer_range' and 'glideslope_range' properties to runways, allowing airport creators to change to the default usable ILS ranges per runway.
Background text and labels are now also shown when 'Bgtext' setting is at 'limited'.
Planes obey speed restrictions on routes even after giving speed instructions, so planes behave like they did before version 5.8.
Departures can be handed off near the boundary when the selected altitude is higher than the 'diversionaltitude'. Before, planes needed to climb above the ceiling (so to the 'above' altitude) before handoffs were possible. Now, departures can leave the airspace while flying level. When using departure routes, there's also the option to override the default 'above' altitude, allowing for level handoffs at lower altitudes.
The traffic now resets by a short press on the custom airport button, and a long press shows airport details.
The 'speedrestriction' property is split into 'speed_near_airport' and 'speed_below_altitude' for more clarity. 'Zoom' is renamed to 'defaultzoom' to allow for more zoom-out. Old files are unaffected.

Changelog for version 5.8.2:

Adjustment to avoid arriving airplanes spawning too close behind slow airplanes.
For custom airports:

Increased the airspace radius limit.
Added 'textpos' property to [areas]; this is for adding centered altitude labels. Older custom airports can keep using the old 'labelpos' (for uncentered altitude text). This change will make everything look the same after updating the game to v5.8.
Added new 'label' option to [background], which works similar to the 'text' option, but instead of centering the text at a given position, it is anchored top-left to the given position, similar to how beacons are labeled.
Hotfix v5.8.3 (4 February):

Fixed a bug (that was introduced in v5.8.2), where boundary coordinates were incorrectly loaded.

Version 5.8 changelog:

You can now draw multiple distance lines using right clicks or using the 'Distance tool' keybinding. Previously you could draw only one line at a time. To remove a distance line, right click on the distance text. And to remove all lines, right click anywhere on the menu bar.
You can now pan and zoom while the game is paused, and the game now starts paused until you click anywhere on the screen.
Added keybindings for less commonly used functions that were previously hidden behind longpresses on the digits on the menu bar. See the Controls screen (F7) to change the keybindings.
LLZ ('cleared for localizer only'). This can be used temporarily to avoid capture of the glide slope (for separation purposes), when ILS mode is enabled.
Resume Normal speed. This allows you to instruct a plane to resume to normal speed in case you had given the plane a speed instruction earlier. Normal speed behavior is similar to previous versions: departures automatically increase their speed. Arrivals reduce their speed to 250 knots when descending below FL100; and to 220 knots at 15 miles from the airport; and to 200 knots when intercepting the localizer. Note that Normal Speed is automatically resumed when intercepting the localizer, even when instructed a speed change earlier.
Turn Direction (toggle between a left or a right turn). Note: these 3 features can also be enabled by longpressing digits on the option bar:
Pause game. Tip: set it to the Alt key if you like the game to pause automatically when Alt-Tabbing. Esc key will always keep working as an alternative way to pause the game.
Improvements to the Help menu. The interface is also translated to Dutch: the language can be toggled in the About menu in case the OS language is set to NL.
Improvement to pilot readbacks: unnecessary 'double readbacks' are now avoided in case multiple instructions are given in quick succession to the same aircraft.
Arrivals now reduce their speed when flying within 15 miles from their destination. Previously all planes reduced within 15 miles from the center of the radar, which was a bit inconsistent. This change mainly affects arrivals to secondary airports that are far away from center of the radar, for example Newark.
Added 1 minute extra time to the Toronto traffic scenario.
Fixed the Lock View function in the Display menu, so it correctly keeps the current radar view fixed when resizing or reloading the game.
For custom airports:
Added the option to draw text to the [background].
The area label location is now centered at the middle of the label text.
Increased the airspace radius limit.

Added a hint to explain how to do parallel ILS approaches without incidents (for example, intercept runway 4R at 2000 feet, and runway 4L at 3000 feet; this will keep the planes 1000 feet apart till they are on the localizer).

New in this version:
✈ Display options

Ident button to toggle on/off the blinking of plane targets that made a call.
Radio button to enable 'Radio Direction Finding': this feature marks planes when they are using the radio, so you can see who is talking. This feature is not only helpful when controlling busy airspaces, it's actually realistic; systems like this are used in real life in some countries.
Captions button lets you hide the blue text at the bottom of the screen. It declutters the screen and adds realism as you have to listen to the pilots carefully (but of course it's only practical to use this feature when voices are enabled). And if you miss a call, just open the menu, because then the blue text will still be displayed.
Clock lets you display the local time. These four new options can be found via the new 'Extra' submenu in the Display menu.
Added XL font size option to the Text button, and adjusted the font size for high DPI displays.
✈ Sound options

Added a Noise button to the Sound menu: when enabled, you will hear a bit of background noise when pilots are talking over the radio, for some extra immersion.
Adjustments to text-to-speech calls and readbacks, for more variation and accuracy.
✈ Small adjustments

For custom airports, the altimeter unit can now be manually set to either inches or hectoPascals by using a new 'inches' property.
The control bar defaults to the bottom of the screen on ultrawide displays.

Changelog of this small update:

Improved accuracy of zooming towards the cursor when using the scroll wheel to zoom (if relative zooming is enabled in the F7 menu).
Corrected ILS pronunciation in readbacks.
Emergency planes can now select higher speeds (above the usual 250KT limit).
Improved callsign selection based on plane spawn location; the callsign selection is now less random but more based on the 'spawn directions' as defined in the airline list of custom airports.
Slightly reduced the separation minima for departures just after takeoff; this should avoid incidents at custom airports with minimum altitudes close to the ground. At the default airports, the minimum altitude of at least 1500 feet avoids triggering of incidents anyway.
Bug fix for planes that could have both ILS and HOLD modes enabled at the same time, causing game instability.
Bug fix for occasional incorrect plane spawn altitude when multiple runways are in use.
Bug fix for emergency planes being unable to select the runway fixes of alternate destinations.

What's new:
Updates to all 9 airports
The updates include more detailed coastlines, changes to restricted areas, added displaced thresholds and waypoints on the localizer (where applicable), corrections for magnetic variance, and updates to various beacons/SIDs. Note: when loading an older savegame for the first time after updating, the newer runway data may cause go arounds on some locations.
Color customization
Added a Color menu, where you can toggle between various colors for things like labels, targets, runways, and more. You can find the Color menu in the Display menu.
Various adjustments

The heading of departures can now be adjusted without having to manually disable SID mode first.
Option to zoom towards the cursor instead of towards the center of the screen. See the Controls menu (press F7) to toggle the 'Zoom Relative' setting between 'Cursor' and 'Center of screen'.
Previous sound setting is saved when switching sound on/off.
Higher max rate of departures by having tighter margins to nearby traffic/clouds.
For custom airports:

Colored lines can be added to a new [background] section at the end of the file.
Lat/Long coordinates can be given in simple decimal degrees (so without needing to add letters) by setting decimaldegrees=true.
Added optional localizer waypoint pronunciation.
The visible part of a circular area can be limited by headings using the drawdegrees property
Added option to add more specific from/to headings to the airline list.
See the example.txt on how to use these new features.

Minor adjustments and bug fixes in v5.5.5 (4 April):

Fixed issue where planes inbound secondary airports could not land after a go-around in case the runway configuration had changed to a takeoff-only config. For example, planes inbound RD airport may now change destination to EHAM after going around.
Blue plane messages now remain visible after a runway configuration change.
Slightly reduced the climb rate of planes just after takeoff.
For custom airports, adjustments to the transition altitude/lowest flight level at USA airports, to make it closer to reality: 'transitionaltitude=18000' will now be interpreted as 17000 to make FL180 available at high pressures, as it is in real life. The lowest selectable FL will not drop below FL180. And the lowest FL will now increase in steps of 10 instead of 5 (for example FL190 instead of FL185). These adjustments only affect 'usa=true' airports with a transition altitude set at 18000 feet and pressure simulation enabled (Realism menu).
Added the property 'transitionlevel', but only to keep better compatibility with older airport files. This deprecated property was removed in v5.5 due to the addition of variable pressure, but now the property will be interpreted as 'transitionaltitude'. Newer airport files can better use either 'transitionlevel' or 'transition' to avoid naming confusion.
Fixed missing displaced threshold for secondary airports.
Planes leaving an APP route will obey speed restrictions.
And v5.5.6 (5 April) fixes an issue where the transition level at YSSY airport was incorrectly calculated.

This version adds extra options that allow you to play in a more realistic way, and the gameplay controls can now be customized to your liking.
Changelog for version 5.5:

Added 3 new options to the 'Realism' menu: Air pressure, Random weather, and Frequencies. By default all 3 options are off, but if you want the gameplay to be more challenging and realistic, switch them on if you like.

The Pressure option adds air pressure simulation (QNH/altimeter). By default it's set to off (like in earlier versions; the pressure is fixed at standard pressure), to keep things simple. But when enabled, you can set the actual air pressure (at sea level) in the Weather menu. The air pressure mainly affects the height of the flight levels and the lowest usable flight level. It does not affect altitudes. To distinguish between altitudes and flight levels, an A or F is added to the label of the airplanes, depending on the transition altitude (the 'highest altitude') at the airport you are controlling.
The Random weather option automatically sets the weather (wind, pressure, and a small chance of clouds) when starting a new game. The weather can still be adjusted in the Weather menu at any time.
The Frequency option can be enabled if you like more realistic handoff readbacks: the H/O button is replaced by a 'radio frequency' button. Players that use custom airports may already have seen (or heard) this feature before, but now it's a toggleable feature.
Added customizable keyboard bindings, and mouse control customization. Press F7 to open the Controls menu (also accessible via the About menu), and click on a function to change its binding. You can setup keys to your liking; you can even bind functions to the A-Z and 0-9 keys, which are by default used for Text Input (like 'A30' for altitude 3000). If you don't use Text Input to control planes, press F6 to disable Text Input, so you can use any key without conflicts. Some mouse controls can also be adjusted, for example the functionality of the scroll wheel in combination with mouse clicks. You can experiment with different control settings and if things go wrong, just press the Defaults button to restore all controls back to the default settings.
Added 'speech rate' setting to the Sound menu. By default, the speech rate changes automatically based on the time multiplier and the number of planes, but now it can be set at a fixed rate.
Simplified the Custom Traffic menu; it now has 4 buttons for all of the 4 custom traffic modes, so there's no need to toggle the 'skill' and 'flow' buttons.
Updated runway names at Luton and Orly due to magnetic variation.
Text Input 'II' can be used as an alternative to longpressing the ILS or SID button.
For Custom airports: option to set the maximum climb rate per planetype.
Various minor adjustments.
Hotfix v5.5.1: fixed issue where Caps Lock or Num Lock interfered with keyboard shortcuts.
