Nano Milestone 11 Released

Universal blocks - Learn More:
Milestone 11 includes support for Universal Blocks to be turned on via a “canary block” at a sufficient network adoption. In the future, version 11 will be the minimum supported version as it is the first version to understand Universal Blocks.

Vote rebroadcasting is now prioritized by the stake they represent.

By the numbers:
107 commits, across 69 files, from 15 contributors!

RPC:

• Support for universal blocks
• Improved account history with new option to include change and open blocks, as well as pagination support PR#668

Performance:

• Reduced database space by ignoring duplicates for unchecked blocks PR#611
• Reworked vote republishing rules to improve receive times #663

Command line:

• Show the correct initial account after importing seed from the command line PR#637
• Command to create database snapshots with compaction without requiring the node to be stopped PR#672

Various changes

• Support for watch-only accounts. This facilitates keyless nodes for deposits PR#581
• Active votes are now broadcasted to newly discovered representatives PR#711
• Bootstrap server improvements to client connection management PR#726
• Fix a bug that could sometimes prevent bulk push PR#723
• Updated initial bootstrap weights

Version 10.0.1 Released

This release is a hotfix to address display precision problems with Mac and Windows wallets. XRB amounts were shown as 100x the expected amount.

Version 10.0 Released

Note: wallet binaries from this release have been removed for a critical UI bug. The bug has been fixed in 10.0.1

This release contains countless performance improvements in regards to bootstrapping, synchronization, and resource usage as well as variety of bug fixes and UI improvements. A major overhaul has been done to the underlying synchronization code, which greatly improves the usability of the Nano wallet for the average user.

This release is the precursor to the full UI redesign being released in the very near future. Regardless, it is recommended to upgrade to this version until then for the performance optimizations.

Performance:
Major overhaul to bootstrapping & block synchronization system
Significant reduction in bandwidth utilization, especially for representative nodes

User Interface:
Fixed UI responsiveness during incoming transaction processing
Improved account balance formatting
Various small UI tweaks

RPC API:
The send RPC has a new “id” parameter that guarantees idempotency when the parameter is utilized. PR #610
HTTP connections are now closed properly. This fixes an issue with certain HTTP clients receiving socket reset exceptions.
Added CORS support PR #244

Bug fixes:
Various potential race conditions in the bootstrapping, synchronization, startup and shutdown processes have been identified and resolved.
Logging fixes/improvements

Other changes:
FreeBSD build now supported PR #600
Added support for --data_path on commandline for all switches PR #586
Initial representative weights are derived from a snapshot during bootstrapping PR #566
SIMD optimizations have been disabled by default PR #352
Updated to Boost 1.66
Added log rotation parameters and max bootstrap connections to config.json
Added command line option to ‘vacuum’ the local datastore. PR #411

NOTE FOR THOSE WHO WERE RUNNING A CUSTOM BUILD OF MASTER:
Hash2 has been removed from this release pending further optimizations. If you were running on master, you may need to reinitialize the ledger as the database format is incompatible with this release.

Version 9.0 Released

RC3 update:

• Fixed an issue where a lock wasn't being acquired causing a crash.

RC2 update:

• Fixed issue on Windows where db would go to 8GB in size right away
• Improved macOS backwards compatibility from APFS and hopefully back to 10.9

This is mostly a stability update for the core node and also includes some performance improvements. This contains a database update and will take several minutes to upgrade on first launch.

• Fixed a race condition that would produce an invalid transaction in some cases.
• Caching certain block information for faster RPC lookups.
• Added ability for blocks to be generated without work attached
• Added a number of convenience RPCs
• Fixed OpenCL PoW generator to work on nVidia cards
• Recording full vote message to assist representative migration
• Removing loopback address as valid peer

The docker tag is clemahieu/rai_node:9 while we're testing the release candidate.

First attempt at offering sha256 sums for binaries. Let me know if any don't match.

• Votes coming off the network no longer cause an IO write every time greatly reducing running IO
• Blocks are processed in a single queue greatly reducing bootstrap disk IO
• Fixed issue where network requests would wait for IO to complete lowering throughput
• Fixed issue where log rotation size couldn't be changed
• Fixed an issue where the database resizing could cause a crash
• Tracking and displaying peer version number in GUI and RPCs
• Fixed a number of issues found with clang sanitizers

Version 7.9.0 Released
