dcrwallet v1.5.1

This release contains bug fixes and minor feature additions. A
comprehensive list of improvements and bug fixes follows.

New features

• An auditreuse JSON-RPC method was added. This method reports all
  transactions that reuse an output address, excluding votes and
  revocations which must use the committed address from a ticket. An
  optional block height parameter may be provided to only search for
  reuse following a block.

• The createrawtransaction JSON-RPC method was implemented directly.
  This allows users of the SPV syncing mode to perform the call, rather
  than the call erroring due to no RPC passthrough to a dcrd JSON-RPC
  server.

Other improvements

• The --csppserver.ca option is now expanded with ~ and environment
  variables.

• The sample config has been updated with options related to
  CoinShuffle++.

Bug fixes

• Duplicate logs for insufficient balance errors during automated
  ticketbuying have been silenced.

• The gRPC method TicketBuyerV2Service.RunTicketBuyer contained a
  regression causing all change to be created for only the default
  (first) account. A fix was made to restore the previous behavior,
  where change is created for the source account.

• An address reuse bug caused by resetting child indexes backwards
  after address and account discovery was corrected. It was possible
  for this bug to be hit any time network synchronization had to be
  restarted (e.g. the dcrd JSON-RPC link was lost), because address
  discovery would always occur on resync.

• A shutdown hang of the dcrwallet process following a panic in a
  JSON-RPC handler was fixed with improved synchronization code.

• A data race in the signrawtransaction JSON-RPC method was
  corrected.

• A memory leak in the JSON-RPC websocket client to dcrd was fixed.
  This bug caused excessive memory usage by retaining every unmarshaled
  response in memory for the lifetime of the websocket connection.

• Extended pubkeys imported via the importxpub JSON-RPC method may
  now be used immediately rather than requiring a restart of the process.

decrediton v1.5.1

This patch release for decrediton mainly focuses on patching various issues that
were found during public usage. We have also included an update to the QR
code that shows a basic DCR logo within.

  include a blue/green DCR logo in the center. Functionally, this will be no
  different than before. (#2385)

• Allow for the second instance warning to be closed and quit the application.
  (#2394)

  while in SPV wallets. (#2389)
