v0.16.0

• A new tool cmd/bnscli for interacting with a BNS node was created.
• Creation of a new proposal in x/gov extension is now restricted to only
  members of the electorate that this proposal is created for.
• Cleanup escrow: removed the support for atomic swap
• A new bucket implementation orm.ModelBucket was added that provides an
  easier to use interface when dealing with a single entity type.
• migration package was updated to provide orm.ModelBucket wrapper for
  transparent schema version migrations
• x/gov package was added, which maintains multiple versioned Electorates and
  ElectionRules that define voting rules (quorum, threshold, voting period) for
  a given Electorate. Votes can be tallied at the end and execute an
  application-defined action which is passed in to the constructor. This is
  compatible with standard handler interfaces and sample application-level
  setup is demonstrated in the test code (and all sample*_test.go code).
• Failed execution of the Proposal intent does not result in a failed
  transaction (so we update the Proposal state properly), but is rolled back
  independently and noted in DeliverResult.Log (reporting to be improved in a
  future issue)
• x/gov adds three internal transations: UpdateElectorate, UpdateElectionRule,
  and TextResolution. TextResolutions can only be created by elections and
  the text is stored in a bucket along with a reference to the electorate
  and proposal that they refer to.
• Enabled x/batch in bnsd. You can now send a batch of messages, which are
  executed atomically as one unit (all succeed, or no changes committed).
• x/gov methods are exposed in bnsd application. The list of messages that
  are eligible for proposals is in cmd/bnsd/app/codec.go.ProposalOptions.
  Note that you can also use a batch message with a subset of possible actions,
  to make multiple SendTx as part of a governance vote, for example.
• Dockerize all the protobuf tooling for easier developer experience and
  reproducible builds
• You can use "seq:multisig/usage/1" or similar in the genesis file to easily
  create addresses without manually encoding everything into 16 hex digits
• Introduce errors.Append function to combine errors into a new multi error
  type
• spec directory now contains protobuf files and testvectors (standard api
  objects in both json and binary encodings) to enable easier bindings and unit
  tests in client code, and projects that import weave.

Breaking changes

• Escrow does not support atomic swap anymore: preimage is removed from Tx and,
  haslock extension removed and arbiter now must be an Address and not a
  Condition
• Metadata attribute was removed from transaction attributes. This affects
  two entities x/cash.FeeInfo and x/sigs.StdSignature
• Max length of blockchain ids used in username NFTs is now 32 (previously 128)

v0.15.0

• Tendermint is upgraded to version 0.31.5
• New x/aswap extension implementing atomic swap functionality. Atomic swap
  implementation is separated from x/escrow
• x/cash is using the new gconf package for configuration. New genesis path
  is used. To update genesis file, replace "gconf": { "cash:xyz": "foo" } with
  "conf": { "cash": { "xyz": "foo" } }
• Removed support for Go 1.10. Minimal required version is now 1.11.4.
• Added support for Go 1.12
• New migration package. Schema versioning for models and messages can be
  implemented by relying on functionality provided by this package.

Breaking changes

• Dependency management was migrated to Go modules. dep is no longer used or
  supported.
• x/paychan extension is using a wall clock for the timeout functionality
  instead of relying on the block height
• gconf package was reimplemented from scratch. Configuration can be changed
  during the runtime using messages.
• Many extensions where updated to provide weave.Metadata and support schema
  versioning as implemented by migrations package. Protobuf messages are
  using new schema and are not binary compatible with old ones. Updated
  extensions are: x/cash, x/currency, x/distribution, x/escrow,
  x/msgfee, x/multisig, x/namecoin,
  x/nft, x/paychan, x/sigs, x/validators

v0.14.0

• Simplify transaction message unpacking with weave.LoadMsg
• Initial version of the governance extension (x/gov)
• Signature verification in x/sigs extension costs gas now
• A new message BumpSequenceMsg for incrementing a user sequence value in
  x/sigs extension
• When considering expiration in x/escrow extension, expiration time is now
  inclusive
• A new validator subjective anti-spam fee was added
