Version: 0.9.9
Date: 2019-09-24
  Bugfixes:
    - Hotfix of a migration issue caused by the introduction of "Idle mode"

Version: 0.9.8
Date: 2019-09-24
  Features:
    - Added option to disable replacement for machines
  Balancing:
    - Added "idle" mode for miners, labs, boilers, generators and reactors
    - Idle machines suffer only 50% of damage in case of failures 
  Changes:
    - Reduced max value for default replacement age from 1000 to 300
    - Changing the default setting for replacement age will now trigger an update for all machine types that used the prior default setting
    - Increased max value for machine specific replacement from 150 to 300
    - Replacement age is no longer neccessary for the internal cycle time calculation. 
  Bugfixes:
    - Fixed GUI issue if display scale is greater than 1
    - Fixed aging of idle machines with a positive number of remaining bonus cycles

Version: 0.9.7
Date: 2019-09-11
  Features:
    - Repair mechanic updated: To repair a broken machine, only repair packs are needed. After providing them, the machine will request additional repair materials, which will in turn significantly reduce repair time.
    - Added a gui to select specific item usage rules for your machines
    - Added maximum operation age: Machines that reach this age (currently 150% of expected operation age) will shut down to prevent critical failures
  Balancing:
    - Repair mechanic update: From now on only repair are needed to repair broken machines. This will make basic maintenance of bases much less of a hassle.
    - Repair mechanic update: The more repair materials delivered, the less time is needed for repair. Repair of a machine only with repair packs will take much more time (5 times more by default). 
    - Demand for repair materials has been adjusted for some machine types
    - Increased range of maintenance unit to 4 tiles, increased energy demand to 76 kW, reduced repair rate to 4 percent
    - Mining young machines (age below 25%) which haven't yet produced anything will not return scrapped machines
  Changes:
    - Increased the setting limit for max machine age to 720 hours (30 days) to accommodate for games on online servers
    - Increased the setting limit for MTBM to 720 minutes (10 hours) to accommodate for games on online servers
    - Initial bonus cycles are now cumulative with wear reduction factor
  Bugfixes:
    - Fixed already delivered maintenance materials not showing up on the production tab as consumption if the coresponding entity was destroyed
    - Fixed missing replacement requests after repair of old solar panels and accumulators
    - Fixed wrong icon size for some scrap items of mod machines
    - Fixed that removing request proxies with a deconstruction planner would grant free repair or replacement. Deconstructed request proxies will now be recreated after some time
    - Fixed that health bars of invisible chests behind machines would be visible if the coresponding machine got attacked

Version: 0.9.6
