Lithium Luna, Point Release 3

Overview

This is the v0.12.3.0 point release of the Monero software, and it is part of the v0.12 network wide update. The major release was due to the April 6th network update, which in turn increased the minimum ring signature size, sorted inputs so as not to leak wallet choice by inference, and slightly changed the proof-of-work algorithm to prevent DoS attacks by ASICs. This release of the software presents a number of major improvements to Monero, as well as a large set of bug fixes.

Some highlights of this point release are:

• Fix for overly abrupt remote node timeouts
• Fix for edge case where a wallet might incorrectly report received Monero

Some highlights of this major release are:

• tweaked PoW to block DoS attacks from ASICs
• added input ordering to prevent wallet inference
• increased minimum ring size from 5 to 7
• subaddress support added, with addresses starting with a prefix of 8
• added multisig support
• added support for SunOS / Solaris
• initial support for Ledger Nano S hardware wallet
• added seed encryption by password
• securely erase keys from memory, for most cases, when no longer in use
• initial Bulletproofs implementation live on testnet
• added accounts, tags, and labels, via subaddresses
