- New safebox hash calculation algorithm to allow safebox checkpointing
- Improved difficulty target calculation to obtain a more stable average blocktime of 5 minutes, given abrupt hashpower fluctuations
- Bug-fix for China region users
- Anti-spam measures
- New Consensus Rule: A block can only contain 1 zero fee operation per sender account. If a sender account issues 2 or more zero-fee operations, that block is invalid.
- SafeBox now stored in chunks to facilitate checkpoint distribution
- Reintroduce orphan blocks operations on main blockchain
- Added Checkpointing:
- Checkpoint created on every 100'th block
- Added network operations to transfer Checkpoint chunks (compressed)
- Addded In-Protocol PASA Exchanging:
- New Operation: List Account, used to list an account for public or private sale
- New Operation: Delist Account, used to delist an account from sale
- New Operation: Buy Account, used to purchase an account lised for sale
- Updated Operation: Transaction, can be used in place of Buy Account operation in private account sales
- RPC API Changes:
- All changes are backwards-compatible for current 3rd-party infrastructure providers (exchanges, wallets).
- However, use of param "ophash" has been changed in V2, see "Operation Object changes" section to know how to use "old_ophash" param value
- JSON changes:
- Account Object changes:
- Added param "state" (values can be "normal" or "listed". When listed then account is for sale)
- If "state" is "listed" then will fill next values:
- "locked_until_block", "price", "seller_account"
- "private_sale" : Boolean value
- "new_enc_pubkey" : (Only on "private_sale" = true) - HEXASTRING with private sale encoded public key
- Added param "name": String
- Name available chars: abcdefghijklmnopqrstuvwxyz0123456789!@#$%^&*()-+{}[]_:"|<>,.?/~
- Name first char: (cannot start with number): abcdefghijklmnopqrstuvwxyz!@#$%^&*()-+{}[]_:"|<>,.?/~
- Name lenght: Empty or 3..64 chars length
- Added param "type": Integer (Valid values from 0..65535)
- Operation Object changes:

- New param "old_ophash": Will return previous "ophash" value only for old blocks (prior to v2 protocol activation)
- New param "subtype" : Based on "optype" param, this param allows to discrimine point of view of operation (sender/receiver/buyer/seller ...)
- New param "signer_account" : Will return the account that signed (and payed fee) for this operation
- Param "enc_pubkey": Will return both change key and the private sale public key value
- About method "findoperation" and "ophash"
- Due to changed "ophash" param value calculation, method "findoperation" will find old "ophash" values too
- This is to avoid 100% compatibility, but remember that returned "Operation object" will contain "ophash" value calculated in new format only (you can read "old_ophash" value in older blocks)

- Fixed bug: On "getaccountoperations" if an account had a lot of operations (receive tx included) then sometimes app crashed when executing depth search.
- Note: High depth search is slow because it search always starting from current state, going backwards, in order to return past balance. This can be a slow method on some account with high transactions volume.
- Added Network Timestamp Adjustment (NAT) to calc valid timestamps
- Minimum 4 active connections to calc median used for NAT, otherwise use local timestamp
- Based on IP's (to prevent a malicious IP timejacking, each IP is only used once)

- Network protocol fixed to 5-5 (Nodes with version prior to 1.5 will not be allowed)
- Added protection for non included operations on a block, to prevent continuous sending. Only will resend operations once.
- Bug #27 fixed: Invalid timestamp on FPC (#27)

- Method "payloaddecrypt" added "unenc_hexpayload" result value with HEXASTRING of unencrypted payload
- Fixed some "Random Memory access violation errors" bugs found caused by multithreading and disconnected nodes
- Fixed issue #23: RPC findoperation fails to find operation by opHash
- Miners best practices: Sending new job with new timestamp every 30 seconds
- Buffering last 10 sent jobs to miners
- Small delay prior to destroy a connection to prevent exception handling
- Minor logs changes
- Added a jobs buffer for miners. This will allow to submit old job solutions (limited buffer). (Fix the "tx" issue)
- Miner jobs will not be sent every time a transaction is received, thet will be buffered and sent every few seconds (Fix the "tx" issue)
- Better network performance, allowing more operations and nodes thanks to buffering before relaying
- Daemon: Allow select on ini file how many connections can handle

- Memory leak fixed on RPC-JSON commands
- Memory leak fixed on node connections
- Improved network speed processing new blocks/operations
- Some minor bugs
- Net protocol upgrade to 4-5
- Introducing "more work" with high priority than "more high". Work is calculated based on target. Higher target (more work) is more important than higher length

- Improved network connection
- Added JSON-RPC port 4003 protection Whitelist (only allowed IP's can use JSON-RPC)
- Adding "maturation" param to "JSON Operation object", return null when operation is not included on a blockchain yet, 0 means that is included in highest block and so on...
- Fixing miner timestamp value to prevent invalid time
- Max JSON-RPC miner connections is now 1000 (before, 10)
- JSON-RPC miner enabled at pascalcoin_daemon (linux daemon)
- Screen messages for daemon
