Rule framework

- multiple profiles can cohexist in the same installation, only one is enabled from user settings
- Process: vessel-wide resource consumer/producers driven by modifiers
- split Supply out of Rule, for additional flexibility
- can use resource amount as a modifier
- many new modifiers, to leverage the information provided by habitat

Features framework

- user specified features are set by a flag in settings
- other features are detected automatically from the modifiers used in the active profile
- inject MM patches during loading screen, before MM is executed
- third parties can check for specific features or profiles by using NEEDS[]
- parts are enabled/disabled automatically depending on features used

Resource cache

- new 'exact, order-agnostic' algorithm for consumption/production chains at arbitrary timesteps
- consider interval-based outputs in depletion estimates

Configure

- new module Configure: can select between setups in the VAB or in flight
- setups can specify resources and/or modules
- setups can include extra cost and mass
- setups can be unlocked with technologies
- configuration UI, that show info on modules and resources for a setup

Habitat

- new module Habitat: replace CLS internal spaces
- used to calculate internal volume in m^3, and surface in m^2
- can be disabled/enabled even in flight to configure the internal space as required
- support inflatable habitats
- can be pressurized/depressurized
- can keep track of level of CO2 in the internal atmosphere
- can be added to parts with no crew capacity

Greenhouse

- improved module: Greenhouse
- lamps intensity is determined automatically, and is expressed in W/m^2
- can have radiation and pressure thresholds for growth
- can require an arbitrary set of input resources
- can produce an arbitrary set of by-product resources
- growth will degenerate if lighting/radiation/pressure conditions aren't met

ISRU

- planetary resource definitions based on real data
- new module Harvester: for crustal/atmospheric resource extraction, use abundance/pressure thresholds

Wet workshops

- some stock tanks can now be configured as either fuel tanks or habitats, even in flight

QualityOfLife

- new module Comfort: replace Entertainment and provide a specific bonus, added to some stock parts
- modified module GravityRing: now provide firm-ground bonus
- living space is calculated from volume per-capita

Radiation

- shielding required is now determined by habitat surface, and map to millimeters of Pb
- rtg emit a small amount of radiation

Planner

- single page layout, with panel selection
- show consumers/producers of a resource in tooltip
- improved/redesigned most panels
- redundancy analysis for Reliability panel

Reliability

- improved subsystem: Reliability
- support arbitrary third party modules
- components are now disabled when they fail
- two types of failures: malfunctions (can be repaired) and critical failures (can't be repaired)
- safemode: there is a chance of remote repairs for unmanned vessels
- components can be assigned to redundancy groups
- an optional redundancy incentive is provided: when a component fail, all others in the same redundancy group delay their next failure
- removed 'manufacturing quality'
- can select quality per-component in the vab, high quality means higher cost and/or mass but longer MTBF

Signal

- improved: focus on data transmission rates and differences between low-gain and high-gain antennas
- high-gain antennas: can communicate only with DSN
- low-gain antennas: can communicate with DSN and with other vessels
- low-gain antennas: can be flagged as 'relay' to receive data from other vessels
- can choose what level of control to lose without a connection:
  . 'none' (lose all control),
  . 'limited' (same as CommNet limited control) and
  . 'full' (only disable data transmission)
- easy parameters for antenna definitions
- simple data rate attenuation model
- render data transmission particles during data transmission
- disable CommNet automatically when enabled
- connection status is obtained by CommNet or RemoteTech when signal is disabled
- new signal panel in vessel info window, show data rates, destination and file being transmitted

Science

- new subsystem: Science, improve on data storage, transmission and analysis
- transmit data over time, even in background
- analyze data over time, even in background
- the background data transmission work with Signal, CommNet or RemoteTech.
- new module: HardDrive, replace stock data container, can flag files for transmission and lab analysis
- new module: Laboratory, can analyze samples and produce transmissible data
- work with all science experiment modules, both stock and third-party, by hijacking the science result dialog
- data storage: can store multiple results of same experiment type, can transfer to other parts without requiring EVA
- data storage: can still be stored on EVA kerbals, and EVA kerbals can take/store data from/to pods
- data UI: show files and samples per-vessel, can flag for transmission or analysis, can delete files or samples
- properly credit the science over time
- do not break science collection contracts

Automation

- removed the Console and command interpreter
- new scripting system: not text-based anymore
- new component control and script editing UI
- script editor UI highlight parts for ease of use

Misc

- ported to KSP 1.2.1
- consistent part naming scheme
- rebalanced mass/cost of all parts
- improved part descriptions
- do not change stock EC producers/consumers anymore
- adapted all support patches, removed the ones not necessary anymore
- shaders are loaded from asset bundle
- removed workarounds for old SCANsat versions
- some Settings added, others removed
- action group support for all modules
- properly support multiple modules of the same type in the same part
- optimized how animations in modules are managed
- can optionally use the stock message system instead of our own
- can optionally simulate the effect of tracking pivots on solar panels orientability
- removed helmet handling for EVA kerbals
- doesn't require CRP anymore, but it will still work along it
- improved how crew requirements are specified in modules
- show limited body info window when Sun is selected, instead of nothing
- new contract: analyze sample in space
- new contract: cross the heliopause
- rebalanced ec consumers/producers
- show tooltips in vessel info
- use common style for all part info tooltips
- AtomicAge engines emit radiation (ThePsion5)
- more love for VenStockRevamp patch (YaarPodshipnik)

Profile: 'Default'

- rewritten from scratch
- balanced consumption rates from real data
- balanced container capacity from real data
- water
- co2 poisoning
- pressurization: influence quality of life
- configurable ECLSS in pods: scrubber, water recycler, pressure control, waste processing
- configurable supply containers: can store Food, Water, Waste
- configurable pressurized tanks: can store Oxygen, Nitrogen, Hydrogen, Ammonia
- greenhouse: require Ammonia and Water, produce Oxygen and WasteWater as by-product, need to be pressurized, has radiation threshold
- stock ISRU plants can be configured with one among a set of reality-inspired chemical processes
- stock drills can be configured with a specific resource harvester
- stock atmo experiment is also used as configurable atmospheric harvester
- stock fuel cells act like real fuel cells
- new part: Chemical Plant, can execute reality-inspired chemical processes, unlocked early in the tech tree
