Orbital Ion Cannon 1.5.3

Just some bug fixes.

Orbital Ion Cannon 1.5.2

New setting "Minimum Cannons Ready Before Auto-Targeting" that allows you to keep a buffer of ready-to-fire cannons that will always be available for manual targeting.
Removed "Verbose Messaging" option -- It is replaced by the new "Custom Alerts" option.
New custom alerts will trigger (if enabled in the mod options) whenever an ion cannon target is designated. These behave just like the alerts for destroyed structures et al.
Switched from using a train stop to show the ion cannon target location on the map to 0.15's new custom map marker feature.
New setting: "Map Marker Duration". This determines for how long the target map markers will remain after the ion cannon fires.
Reworked some text strings & added descriptions to the mod's technologies.

Orbital Ion Cannon 1.5.1

Fixed an error when trying to start a train mini-tutorial.
Reinstated printing the name of the radar that designates an auto-target if Verbose Messaging is enabled.
Fixed a rare bug when both quickbar & inventory slots were completely filled, manually using an ion cannon targeter could cause it to disappear.

Orbital Ion Cannon 1.5.0

Updated for Factorio 0.15.

Auto-Targeting of ion cannons no longer requires dedicated Auto-Targeting Stations.
Instead, after researching Auto-Targeting, any radar scanning activity will scan for nests and target ion cannons as needed.
Additionally, there is a new option to detect any nest expansions within the always-revealed regions of radar coverage and auto-target them accordingly.
Do be cautious with this option enabled, as biter nests expanding in close proximity to your own structures can result in friendly fire.

Disabled the annoying "Rocket launched without satellite!" message.
Added Orbital Ion Cannons as tracked items in the new "Rocket silo stats" frame.
New research costs.
Added support for the new "Expensive" recipes option in Factorio 0.15.
Auto-targeting now fires the custom "on_ion_cannon_targeted" event.
Auto-targeting should no longer leave spurious "target location" markers on the map; they should now properly disappear after the ion blast.
Added custom event "on_ion_cannon_fired", which now properly activates when the ion cannon blast actually occurs. See the Readme for documentation.
Added support for in-game mod options (Options -> Mods).
Added a mod option to toggle auto-targeting.
Removed the "proximity check" option. Be sure to be careful about your target designation, as always.
Removed the "lockout ticks" option; there are now always 10 lockout ticks (1/6 second).
Renamed remote call "fire_ion_cannon" to "target_ion_cannon".
The Ion Cannon Targeting Device is now unlocked upon research of the technology, rather than upon launching the first ion cannon.
It is no longer possible to switch to the "Full" ion cannon gui when there are 40 or more ion cannons in orbit.

Orbital Ion Cannon 1.4.6

The ion cannon GUI hotkey now only works when there is at least one cannon in orbit.
Added config option for adjusting how much area Auto-Targeting Stations permanently reveal around themselves.
Reduced "Ion Cannon Ready" spam when firing several ion cannons -- the minimum duration between announces can be found in config.lua.
Renamed custom "on_ion_cannon_fired" event to "on_ion_cannon_targeted", to better reflect that it fires on target designation rather than actual blast impact.
The "on_ion_cannon_targeted" event position is no longer slightly off-center, and now also passes an event.radius variable.

Orbital Ion Cannon 1.4.5

Reduced "Ion Cannon Ready" spam by allowing multiple cannons to become ready in the same second.
Simplify code now that the StdLib print-force function is available in the base game.

Orbital Ion Cannon 1.4.4

Updated for Factorio 0.14.

Orbital Ion Cannon 1.4.3

Close any instance of the old stats window still open.

Orbital Ion Cannon 1.4.2

It is no longer possible to shift+click with the Targeting Device and place useless ghost entities.
Moved the ion cannon status GUI from gui.top to gui.left.
Added an option in the config file to disable the ion cannon blast flames, should you wish to eliminate the chance to cause wildfires with your orbital bombardment.

Orbital Ion Cannon 1.4.1

Auto-designated targets within a chunk are now randomized, rather than being biased towards the northwest corner of the chunk.
Added radius visualization to the Ion Cannon Targeting Device. Now you can see just how far away from the blast zone you need to be!
Along with the radius visualization, the Targeting Device acquired new tooltip data; feel free to ignore the "Shooting speed" bit, but the rest should reflect the values from config.lua.
