3.0.5
Final release by Centure developers
Relicensed under the GNU Lesser General Public License v3
General maintenance, version bump of most electron/vue/node libraries, update of checkpoints and other data etc.
UI - Transaction export functionality
UI - Add a basic about dialog displaying licensing information
3.0.4
Maintenence release, no major changes.
3.0.2
CORE - Fix a crash that was triggering on windows builds
3.0.1
Software rebrands to Munt name.
This build represents our final switch from Qt to Electron for UI builds, Qt is completely removed from the codebase, users who require Qt specific functionality should remain on 2.5.0 until the 3.x series matures and gains more features
UI - New electron based UI
CORE - Switch to guix for macOS builds as well; all official builds now done on guix
CORE - Update various library dependencies to latest versions
NET - Bump MIN_PEER_PROTO_VERSION to 70020; This will disconnect from network all peers not on 2.5.0 or above
UI - Native M1/arm64 builds for macOS
2.5.0
Introduce reward changes
At block 1'619'997 chain forks and per block dev reward is removed, with a once off dev payment of 100'000'000 NLG paid into address GSTG9pQ6yRdGurmjUDGwm8FyYc272vP13b
To keep the eventual supply at exactly 700'000'000 other small changes are then made:
* First halving is brought forward to block 2'074'989
* We slightly alter the rounding of each halving step to give cleaner numbers
* We continue halving for more rounds all the way down to 0.00000001 reward
* Final reward amount continues until block 433'009'989 with the 12.2709 NLG for this period being slowly paid out over a very very long period
Halving schedule as follows (every four years):
5 mining, 7.5 witness
2 mining, 4 witness
1 mining, 2 witness
0.5 mining, 1 witness
0.2 mining, 0.5 witness
0.1 mining, 0.2 witness
0.05 mining, 0.1 witness
0.02 mining, 0.05 witness
0.01 mining, 0.02 witness
0.005 mining, 0.01 witness
0.002 mining, 0.005 witness
0.001 mining, 0.002 witness
0.0005 mining, 0.001 witness
0.0002 mining, 0.0005 witness
0.0001 mining, 0.0002 witness
0.00005 mining, 0.0001 witness
0.00002 mining, 0.00005 witness
0.00001 mining, 0.00002 witness
0.000005 mining, 0.00001 witness
0.000002 mining, 0.000005 witness
0.000001 mining, 0.000002 witness
0.0000005 mining, 0.000001 witness
0.0000002 mining, 0.0000005 witness
0.0000001 mining, 0.0000002 witness
0.00000005 mining, 0.0000001 witness
0.00000002 mining, 0.00000005 witness
0.00000001 mining, 0.00000002 witness (Stays here until completion - block 433'009'989)
2.4.11
This build aims to be the final 2.4.x series release after issues were found that prevented 2.4.8 from being so.
As such it will likely represent the final Qt UI release with 2.5 series of builds replacing Qt with the electron UI.
CORE - Implement several important fixes to the fast path of the "index based" portion of the coin cache, these issues would have resulted in nodes temporarily falling out of sync (until restarted) in some instances had the fast path been turned on however it has been off until now
CORE - Turn on the fast path for "index based" portion of the coin caches, this should drastically improve node performance in some instances
CORE - Introduce optimised sha256 implementations to take advantage of available CPU features (SSE4, neon etc.) when available/possible
CORE - Various performance improvements, removal of lock contention in some instances
CORE - Various improvements to mutexes to make it easier to spot issues as well as for better performance
CORE - Improved debug logging in various places throghout the program
CORE - Update linux builds to GCC 11
CORE - Update macOS builds to clang 14 (sdk 12)
CORE - Update android builds to clang 12 (ndk r23b)
CORE - Update windows builds to GCC 10
CORE - Switch to guix instead of gitian for official builds (all except macOS which will switch also for subsequent releases)
CORE - With all compilers updated we are now able to target C++20
CORE - Update libraries (boost 1.77.0; zmq 4.3.4; univalue 1.0.4; leveldb 1.22+)
CORE - Flush chainstate more frequently to prevent nodes having to resync if they terminate uncleanly after a full sync etc.
LITE - Fix issue that was preventing lite wallet from functioning on testnet
LITE - Fix a crash on macOS at program exit
LITE - Fix/improve behaviour of loading/synchronisation screen and make it smoother
LITE - Native M1/arm64 builds macOS
RPC - Add a 'loaded' paramater to results of 'getmempoolinfo' command
RPC - Improve/fix 'fundrawtransaction' command that failed in some instances
RPC - Improve/fix help text for several commands
QA - Introduction of more unit and functional tests
Dozens of other stability, code quality, build system, testing etc. related fixes and improvements.
2.4.8
Final maintanence release ahead of upcoming 2.5 series of builds; 2.5 will fully activate witness sync and drop the deprecated Qt UI in favour of the electron one (Edit: This ended up not being the case)
2.4.7
CORE - Fix an issue that would cause witness loop to terminate under some error conditions
CORE - Remove behaviour that would cause a complete resync under some error conditions, only do this on mobile/spv wallets and favour a plain assert on regular wallets instead
RPC - Improve output for `validateaddress` command when used on witness addresses
MISC - Various minor logging improvements to help with stability and user support
2.4.6
CORE - Introduce a discount on relay fees for transactions that contain mining/witness rewards
2.4.5
CORE - Chain stability fix for rare issue experienced by some peers
2.4.4
UI - Fix witness earning estimates for recent reward changes
CORE - Improve regression in coin cache performance
2.4.3
CONSENSUS - Fix an issue with fresh syncs stalling, regression was introduced in 2.4.1 release
CONSENSUS - Fix a rare issue with index based utxo getting corrupted (memory only, disk data remained valid)
CORE - Fix an issue that was causing unnecessarily frequent flushing to disk; this should bring large performance improvements for machines with slow disks
CORE - CORE: Major load time performance increase on large wallets, especially on machines with slower disks
CORE - Introduce some code that makes it easier for users that missed the fork to update with any manual intervention
CORE - Introduce some performance improvements to the code
CORE - Various regtest/testing improvements and general codebase cleanup
2.4.1
RPC - Add arena setup time to "gethashps" output
RPC - New command "getlinkedaccount" as counterpart for existing "importlinkedaccount" command
CORE - Fix a DoS attack that can be utilised against miners
2.4.0
CONSENSUS - Implement proposed reward reductions and halving, as decided by community and GAB
Reward changes to take place at block 1'400'000
Halvings every 842'500 blocks, this is roughly four years assuming stable block times (a tiny fraction over in order to make things work out smoothly)
Very minor truncation based rounding applied when halving in order to keep numbers clean and end on a clean supply amount
Final supply of 700'000'000 with last reward mined on block 17'727'500

CORE - Minor stability fixes
2.2.0.0
This release incorporates several major feature branches, which combined involve over years of major development effort.
Highlights include:
* The final phase of our PoW² rollout, which brings new functionality to witness addresses/accounts
* Our new 'v2' transaction format
* Unity; A single unified codebase backend that is shared between desktop and mobile wallets
PoW² phase4:
CORE - Ability to compound witness earnings becomes active
CORE - Delta difficulty adjustments now uses the more accurate witness time instead of the mining time, which should improve block timings and reduce hash rate swings
UI - Easily toggle compounding on/off for a witness account
UI - Extend the locktime and/or quantity of a witness account via UI
UI - New optimise button which can be used on large witness accounts (>1% network weight) to divide/combine into smaller/larger parts for better earnings
UI - Improved dialog for funding witness accounts; Also automatically optimizes large witness accounts (>1% network weight) into multiple parts when creating if appropriate
RPC - Various Phase4 RPC commands become active:
Add funds to a witness account and/or extend the lock period - extendwitnessaccount "funding_account" "witness_account" "amount" "time"
Add funds to a witness address and/or extend the lock period - extendwitnessaddress "funding_account" "witness_address" "amount" "time"
Split a witness account into multiple witness addresses; Lock period is not changed this exists for the benefit of users whose weight is too large for the network - splitwitnessaccount "funding_account" "witness_account" "amounts"
Merge multiple identical witness addresses into a single one; Only works on identical accounts i.e. ones that have previously been split - mergewitnessaccount "funding_account" "witness_account"
Change the witness key on an account where the key may have been compromised or as a periodic precaution - rotatewitnessaccount "funding_account" "witness_account"
Change the witness key on an address where the key may have been compromised or as a periodic precaution - rotatewitnessaddress "funding_account" "witness_address"
Set a witness account to compound all or part of the earnings it receives - setwitnesscompound "witness_account" "amount"
Check the compounding settings for a witness account - getwitnesscompound "witness_account"
Set an address or script other than the default for witness reward payout - setwitnessrewardscript "witness_account" "destination" force_pubkey
Get the current address or script that has been set for witness reward payout - getwitnessrewardscript "witness_account"
Set the compounding template for a witness account; Can be used to managed advanced configurations of how the reward should be paid out - setwitnessrewardtemplate "witness_account" [["destination1" (,"amount") (,"percentage%") (,"remainder") (,"compound_overflow")], ["destination2" ...], ...]
Get the compounding template for a witness account - getwitnessrewardtemplate "witness_account"
v2 transaction format (SegSig):
CORE - New compact transaction format, with a "only pay for what you use" philosophy. Extensible transaction output/input types and flags for easier future extendability in various directions. Uses various built in methods like compact amount representation to ensure transactions are as small as possible while being efficient to process.
CORE - Transaction functionality like RBF using proper built in flags instead of magic values
CORE - Three new initial transaction types (extensible to more)
* Script - Bitcoin compatible 'script' format as in v1 transaction format, for more complex types of transactions that require this functionality
* StandardKeyHash - A compact and concise format for regular day to day transactions without the extra unnecessary processing overhead of a scripting language
* PoW2WitnessOutput - A compact and concise format for witness transactions; Replaces the sub-optimal requirement of placing all the witnessing information in; More compact, faster to process and leads to a cleaner code base
CORE - Compact transaction signatures used throghout for smaller transaction size
CORE - Introduce 'index based outpoints' to new transaction format; allowing for reduction of transaction size in many cases.
CORE - Remove unncessary requirement of 'OP_0' from multisig transaction signatures (Legacy bitcoin bug)
CORE - Transaction signatures are seperate from the transaction script; Similar to SegWit, but done in a more efficient way that doesn't have to worry about backwards compatibility
CORE - Remove sources of transaction malleability; Similar to SegWit, but done in a more efficient way that doesn't have to worry about backwards compatibility

Split a witness account into multiple witness addresses; Lock period is not changed this exists for the benefit of users whose weight is too large for the network - splitwitnessaccount "funding_account" "witness_account" "amounts"
Merge multiple identical witness addresses into a single one; Only works on identical accounts i.e. ones that have previously been split - mergewitnessaccount "funding_account" "witness_account"
Renew a witness account that has expired due to failiure to witness - renewwitnessaccount "witness_account"
Change the witness key on an account where the key may have been compromised or as a periodic precaution - rotatewitnessaccount "funding_account" "witness_account"
Change the witness key on an account where the key may have been compromised or as a periodic precaution - rotatewitnessaddress "funding_account" "witness_address"
Set a witness account to compound all or part of the earnings it receives (phase 4 only) - setwitnesscompound "witness_account" "amount"
Check the compounding settings for a witness account - getwitnesscompound "witness_account"
Set an address or script other than the default for witness reward payout - setwitnessrewardscript "witness_account" "address_or_script" force_pubkey
Get the current address or script that has been set for witness reward payout - getwitnessrewardscript "witness_account"
RPC - GetBlockTemplate support for mining in conjunction with phase 3 witnessing.
* SegSig - A new transaction format. See https://github.com/Gulden/gulden-official/blob/master/technical_documentation/transaction_format.md for technical information.
Highlights include: Solving of malleability issues; More compact transactions (over 50% in some cases) leading to increased network capacity for peak transaction periods; New transaction types (for PoW²); Extensible transaction types for future development.
CORE - Implement fixes for transaction malleability
CORE - Implement new more compact transaction format
CORE - Implement two new transaction types "StandardKeyHash" and "PoW2_Witness"
CORE - Implement version scheme allowing easy future creation of additional compact special purpose transactions
CORE - Witness based version bit activation, for better control of future updates. Feature activation can now be controlled by "miner voting", "witness voting" or a combination at developer discretion.
* Sonic - The sonic project involves multiple changes to the p2p networking stack within Gulden.
Highlights include: A switch to boost::asio for the networking stack to replace the old select() based networking code; Multiple improvements to the initial chain synchronisation process, including reverse header synchronisation, making it drastically faster; Removal of limitations to how many peers a server can handle, which helps solve scalability/congestion issues on the network in peak usage periods.
* Non exhaustive list of additional general changes.
UI - Gulden desktop client gains an automatic update check to alert users of updates. Update check is cryptographically secured to ensure that it cannot be tampered with.
UI - Improved handling of wallet alerts/warnings through a new warning dialog.

CMDFLAG - Add a -windowtitle command flag, primarily intended to be used to assist with testing so that multiple program instances can be easily distinguished.
CMDFLAG - Add a new -disableui flag to start with just a RPC console (and wallet); Useful for some types of debugging.
RPC - New command 'getaccountbalances' return a list of individual balances for all accounts.
RPC - New command 'listunspentforaccount' as account specific counterpart for listunspent.
RPC - New command 'rescan' to trigger a wallet rescan (Same as Tools>rescan via UI).
