Significant changes from previous tags, check the changelog and documentation for migrations.

• Breaking Change! list.set(item) returns the item's chain now, not the list chain.
• Client and Server GUN servers are now more up to spec, trimmed excess HTTP/REST header data.
• Gun.is.lex added.

• Native node links for shorthand graph structures
  You can now easily link nodes by passing it's gun reference, gun.get('mark').path('owner').put(gun.get('cat'))
• Core integration for lists/tables/collections
  Gun now supports a shorthand for lists using the .set method: gun.get('users').set(gun.get('person/mark')).

Amazon S3 driver compatibility/updates for breaking changes in v0.3.0

Fixes for Express.js compatibility

• Server side default .wsp() renamed from .attach().
• .set() deprecated because it did a bunch of random inconsistent things. Its useful behavior has now become implicit (see below) or can be done explicitly.
• .not() it was previously common to return the chain inside of .not, beware that if you have code like gun.get(key).not(function(){ return this.put({}).key(key) }).val() cause .val() to be triggered twice (this is intentional, because it funnels two separate chains together) which previously didn't happen. To fix this, just don't return the chain.
• .put() and .path() do implicit .init() by default, turn on explicit behavior with Gun({init: true}).
• .get(soul, cb) cb is called back with err, node rather than err, graph.
• Options opt.wire renamed from opt.hooks.
• .val() when called empty automatically cleanly logs for convenience purposes.
• .init() added.
• Gun.is.val renamed from Gun.is.value.
• Gun.is.rel renamed from Gun.is.soul.
• Gun.is.node.soul renamed from Gun.is.soul.on.
• Gun.union.ify renamed from Gun.union.pseudo.
• Gun.union.HAM renamed from Gun.HAM.
• Gun.HAM is now the actual HAM function for conflict resolution.
• Gun._.state renamed from Gun._.HAM.
• Maximum Callstack Exceeded is less problematic now, unless you intentionally choke the thread. #95
• Putting a regex or Date or NaN is actually detected and causes an error now while before it was silent. #122 #123
• .on() gets called when a key is later newly made while before it did not. #116
• .val() should not ever get called with a relation alone (internals should resolve it), this is fixed. #132
