Changes in 0.7.0 (Thu Feb 20 2014)
|
|
- Fix an issue when parsing scripts which contain a multi-signature script
|
|
which require zero signatures such as testnet block
|
|

|
|
(https://github.com/conformal/btcscript/issues/7)
|
|
- Add check to ensure all transactions accepted to mempool only contain
|
|
canonical data pushes (https://github.com/conformal/btcscript/issues/6)
|
|
- Fix an issue causing excessive memory consumption
|
|
- Significantly rework and improve the websocket notification system:
|
|
- Each client is now independent so slow clients no longer limit the
|
|
speed of other connected clients
|
|
- Potentially long-running operations such as rescans are now run in
|
|
their own handler and rate-limited to one operation at a time without
|
|
preventing simultaneous requests from the same client for the faster
|
|
requests or notifications
|
|
- A couple of scenarios which could cause shutdown to hang have been
|
|
resolved
|
|
- Update notifynewtx notifications to support all address types instead
|
|
of only pay-to-pubkey-hash
|
|
- Provide a --rpcmaxwebsockets option to allow limiting the number of
|
|
concurrent websocket clients

|
|
and 100k, respectively (https://github.com/conformal/btcd/issues/71)
|
|
- Add rate limiting of free transactions to the memory pool to prevent
|
|
penny flooding (https://github.com/conformal/btcd/issues/40)
