NavCoin Core v4.5.2 - Further Community Fund hotfixes and faster blockchain sync
NavCoin v4.5.2 Release Notes
4.5.2 contains a hard fork which explicitly rejects blocks from obsolete versions (4.5.1 and below) signalled by version bit 21. Upgrading to 4.5.2 will avoid a potential network fork (as described below) and ensure you remain on the same blockchain as the rest of the network.
Community Fund Duplicate Payment Hard Fork
<Pull Request 413>
<Commit 7ef765b>
Fixes a bug where the Community Fund payment requests could be accepted by the network multiple times. Enforces version bit 21 for all blocks after blockheight 2882875 (approximately Saturday 16 February @ 1830 GMT) as well as rejecting duplicate payments after the fork height.
Voting Cycle Counter Hotfix
<Pull Request 396>
<Commit a6782c3>
Fixes a bug where the votingCycle field of community fund proposals and payment requests would continue to increment after their terminal state if a user reorgs. Also for proposal/payment requests which change from pending to expired, when the voting cycle is 1 over the cycle limit, staker's votes would continue to be counted even though such proposal/payment request is expired. This bug did not affect network consensus on the status of proposal or payment requests.
Faster Blockchain Sync
<Pull Request 390>
<Commit 1990d92>
Keeps a cache of the community fund votes to avoid an unnecessary recalculation per block which was causing extreme slow synchronization per block. After applying the patch the CountVotes() function is significantly faster.
RPC Tests newly implemented and fixed
The RPC unit test work mainly involved fixing broken RPC tests inherited from Bitcoin as well as creating new ones. This expands our test suite allowing for greater coverage which provides quality checks to the existing codebase and future updates.
- Fixes to 17 rpc tests inherited from Bitcoin and implements 2 new tests <Pull Request 405><Commit ed3f590>
- Added rpc help test <Pull Request 392> <Commit 6707a98>

*The hashes of Windows .exe builds are currently nondeterministic. The hashes shown here will match the binaries attached to this release, but if you build from source you will end up with a different checksum. Users who are concerned with the checksums of .exe builds should compile their own builds to verify this.
