Chronos update 1

** There will be a hard fork on block height 1280000 (November 11, 2020) **

This required update addresses a flaw in the handling of Unix time based transaction unlocks. It must be installed prior to the planned hard fork at block height 1280000 (approximately November 11, 2020).

See release notes for 0.14.0.0 for additional information about the upcoming hard fork and other recent improvements.

Chronos

** There will be a hard fork on block height 1280000 (November 11, 2020) **

This mandatory update incorporates many reliability, performance, and feature improvement including the following notable enhancements:

Addition of multisig functionality to the wallet
Improved difficulty re-targeting to reduce variance in block times

** There will be a hard fork on block height 1280000 (November 11, 2020) **

Aletheia (point release 1)

This maintenance release contains dozens of reliability and performance improvements from the AEON community as well as upstream, including

New notify daemon and wallet options for event-driven handling of blocks, txs, reorgs, and block rate changes (enhancement)
Fixed incorrect reporting of inputs amounts the CLI wallet when creating a new transaction
Numerous fixes needed for building with GCC version 9.1
Fixed broken DB migration when upgrading in-place without a resync
Fixed numerous potential information leakages when using wallet with an untrusted/public node

Aletheia

This mandatory release improves the long term stability, sustainability, decentralization, and performance of the blockchain by removing the ASIC-resistant PoW (which requires frequent forking in an arms race with ASIC-developers) and replacing it with the much faster-to-verify and ASIC-friendly (currently FPGA-friendly) Keccak-based KangarooTwelve (K12) algorithm. The use of K12 for PoW was reviewed and approved by the Keccak-team, developers of Keccak/SHA3.

It also contains numerous other improvements for reduced transaction size, improved fungibility, safer long-term blocksize growth, and dozens of performance and reliability patches.

The mainnet fork date is scheduled on October 25 (height 1146200)

Changes include:

KangarooTwelve (K12) Keccak variant PoW for FPGA- and eventually ASIC-friendly protocol stability
Borromean signatures for smaller transactions
Tighter big bang protection preventing exponential blockchain growth
Consensus lock time aligned with reference wallet preventing alternate wallets from damaging fungibility
Fixed ring size at 3 for improved fungibility
Gamma-distribution selection on non-RCT outputs for better ring member ambiguity
Improved non-RCT tx output selection for reduced transaction linkages
Upstream reliability and performance improvements
AEON community-contributed improvements

Thanks to stoffu for the majority of the AEON-specific work and additional thanks to all of the AEON community and upstream contributors

Sophia (point release 9)

Sophia (point release 9)

Several dozen upstream reliability, security, and performance improvements
Fixes for upstream exploits not believed exploitable in AEON but patched for defensive and maintenance purposes.
Various build and packaging improvements from the AEON community

Recommended for all users.

Sophia (point release 8)

This maintenance release fixes a problem that existed in 0.12.7.0 only when using the wallet on Windows, and in addition contains a cosmetic improvement to logging and some documentation cleanup. If you are not running Windows there is no need to update from 0.12.7.0.

Note: The initial linux binary was built with an incorrect version tag. This has now been corrected.

Sophia (point release 7)

Dozens of upstream performance, reliability and security patches
Several documentation and configuration improvements from the AEON community

All users running nodes on the p2p network should update ASAP to prevent possible database corruption and loss of synchronization with the rest of the network.
