MintCoin 2.1.2

ℹ️	This is a source-only release, to allow building on the aarch64 CPU architecture. Unless you are planning on compiling for this 64-bit ARM CPU, please consider using a binary from the 2.1.1 release.

The following changes are in this release:

• Remove unsupported Qt build for macOS 10.11
• Fix typo in GUI for number of blocks before a newly minted coin is accepted
• Windows build fixes
• Build fixes for Boost 1.71
• aarch64 support

MintCoin 2.1.1

Bad people are bad.

This release is mostly because we had some infected binaries published on GitHub for version 2.1.0. These were taken down as soon as they were discovered and all accounts that could have published these were
either disabled or had their passwords updated. To help people using the MintCoin wallet be sure that they are using a clean version, we are releasing 2.1.1.

There are only two real changes to the code, both minor:

• We work better with the en_DK local, which provides ISO 8601 formatting for dates & times.

• A few warnings for potential problems spotted by the most recent gcc compiler version were fixed.

MintCoin 2.1.0

Welcome back, MintCoin!

This is the first release of MintCoin in more than 2 years. The primary focus has getting the code working on modern systems, as well as fixing the most painful user issues.

• Peers updated from DNS #43
  No longer will you have to give hints to the wallet so it can know where to connect by setting addnode= in your MintCoin.conf. An initial set of peers is pulled from the DNS.

  Note: We are looking for more people to run a DNS server. Scripts to set this up are in the MintCoin-DNS-lookup-server repository.

• Fix for out-of-memory in Windows 32-bit wallet
  Building the Qt wallet for Windows to be "large address aware" fixes the crashing that many Windows users experience. Some more details can be found here.

• Display when the next coin will be available for minting as a tooltip #57

  

• Support for ARM CPU #44
  The wallet can run on single-board computers (SBC) if they have enough RAM (about 2 gigabyte).

• Scary warnings fixed #59 #60 #61

• Build fixes
  We have a ton of fixes for Linux (both Debian-based and Fedora distributions), Windows, and macOS builds.

• Lots of other bug fixes
  There have been quite a few other small fixes and documentation changes.

MintCoin 2.1.0-beta1

Welcome back, MintCoin!

This is the first release of MintCoin in more than 2 years. The primary focus has getting the code working on modern systems, as well as fixing the most painful user issues.

Please test it out, especially if you are having problems starting or running on Windows due to memory issues. It will use your existing blockchain and wallet without modification.

Back up your wallet.dat before trying new software, as usual. BACK IT UP NOW!

Note that this is a beta, so no guarantees. But I've been running code from this branch for months now and it basically seems to work.

• Peers updated from DNS #43
  No longer will you have to give hints to the wallet so it can know where to connect by setting addnode= in your MintCoin.conf. An initial set of peers is pulled from the DNS.

MintCoin v2.0.2

RECOMMENDED UPDATE - v2.0.2

This is a security and maintenance patch for the 2.0 branch of MintCoin. As work towards the 2.1 overhaul is being extended, we are continuing to make adjustments and forward compatibility patches to our current release branch (2.0). Included in this release are a number of updates related to security. Though mostly edge cases, we feel it is important to include such patches for completeness.

SUPPORT FOR 3RD PARTY TRANSACTION URLS

Included in this release is optional support for 3rd party transaction URLs (Block explorer links). The setting is accessed from within the GUI's options window in the "Display" tab. Users can enter URLs to as many Block Explorers Transaction pages as they like and each entry (after restarting the client) will then be a clickable item in the transaction history's context menu.

This eliminates the need to manually copy/paste a TXID into a block explorer's search field. Some example URLs to include in this field are:

https://chainz.cryptoid.info/mint/tx.dws?%s.htm
https://www.cryptopia.co.nz/BlockExplorer?id=240&txId=%s

SECURITY / DEPENDENCIES UPDATES

• [f21ebad] Guard against OpenSSL's new strict DER checking
• [1696dc1] Miniupnpc 1.9 API compatibility
• [a5d130c] Fix invalid signature with crafted length (PPC)

CLI / GUI UPDATES

• [470bfb4] Optional support for 3rd party transaction URLs
• [2215305] Display the Berkeley DB version used in debug.log and RPC Console UI
• [e8e2d96] Clean up GUI Tooltips and status message handling

MISC UPDATES

• [a07643d] Add new DNS Seeder from Fuzzbawls
• [02eea6f] Update Windows Installer Support Files
• [2edf6f2] Update Checkpoints
• [2a9ac23] [8ba9d18] Update OS Specific makefiles
• [bca38bc] Basic Documentation Update

HOW TO UPDATE

Since this release still runs on the single-file database format, updating is a simple process of replacing your binary executable from one of the downloads below. Please make sure that no MintCoin processes are currently running before replacing this file! Once the file has been replaced, start up your wallet/daemon as usual.

WINDOWS INSTALLER RETURNS

Windows clients now again have the option of using a self-contained installer (available below) to install MintCoin on their systems. The installer places the binaries in your Program Files folder and adds a handy Start Menu Icon for easy launching.

All startup and RPC commands from previous versions, as well as conf file format remain the same.
All Images, Logos, and GUI elements remain consistent with previous 2.0 branch releases.

Release 2.0.1.0

OPTIONAL UPDATE - v2.0.1.0

This patch is intended to be the last release of the 2.0 branch and the "beginning of the end" for the old and outdated single-file blockchain database structure. Before the next major version however, we wanted to make some of the network/message/cpu optimizations available. Some of the changes included in this release are:

• Back ports from mainline bitcoin to improve message handling.
• Disable some mining code that is no longer used during the pure proof-of-stake phase.
• Bloom filter feature added to increase privacy.
• Many small network optimizations.

The biggest benefit is much lower CPU usage and bandwidth used. While memory consumption still remains on the "high" side, a few memory leaks were fixed that will prevent a situation of exponential memory usage increase from occurring when the wallet is left open over extended periods of time.
