v0.6.2

• Add simulation.find.
• Treat strength as zero if x.x or y.y is NaN.

v0.6.1

• Reduce the default link.strength on heavily-connected nodes (#30).
• Reduce the default manyBody.strength to -30.
• The link.strength and link.distance accessors are now passed the correct arguments.

v0.6.0

• Add simulation.fix and simulation.unfix (#27).
• Add simulation.alphaTarget (#26).
• Add simulation.alpha.
• Optimize and area-bias d3.forceCollide to improve stability (#24 #25).
• Change the meaning of simulation.alphaDecay.
• Change simulation.restart to not affect the simulation’s alpha.

v0.5.0

• Replace d3.forcePosition with d3.forceX and d3.forceY.
• Better resolution of exact coincidence along x or y, not just x and y (#23).
• Fix for exact coincidence in d3.forceCollide.
• A few optimizations.

v0.4.1

• Fix bug in d3.forceLink initialization.

v0.4.0

• Change the default simulation.alphaMin to 0.001.
• Optimize the initialization of d3.forceLink.
• Remove d3.forceContain.

v0.3.0

• Rename simulation.start to simulation.restart.
• Add link.iterations and collide.iterations for more rigid constraints.
• Improve the stability of the d3.forceLink and d3.forceCollide forces.
• Increase the default link strength to 0.7.
• Decrease the default drag to 0.4.

v0.2.2

• Change simulation.tick to always advance the simulation by one step, to not dispatch a tick event, and to return alpha < alphaMin. (The tick event is still dispatched by the simulation’s internal timer, which can be controlled via simulation.start and simulation.stop.)

v0.2.1

• Deterministic initialization using phyllotaxis!
• Fix a bug implementing manyBody.distanceMin.

v0.2.0

• Changed force.initialize to take an array of nodes, not the simulation.
• You can now pass a radius to d3.forceCollide.
• The links argument to d3.forceLink is now optional and defaults to the empty array.
• The nodes argument to d3.forceSimulation is now optional and defaults to the empty array.
• Removed the start event from simulation.on.
• Fixed simulation.start, simulation.stop and simulation.tick; you can now tick manually.
