v12.2 Testing is now open !

Hello everyone,

Looks like we finally had a successful migration on testnet and solved all known (critical) issues, so we are ready to start the final phase which is a public testing.

This release includes:

• DIP0001 implementation https://github.com/dashpay/dips/blob/master/dip-0001.md
• 10x transaction fee reduction (including InstantSend fee)
• InstantSend vulnerability fix
• Lots of other bug fixes and performance improvements
• Experimental BIP39/BIP44 complaint HD wallet (disabled by default, should be fully functional but there is no GUI yet)

Detailed release notes: https://github.com/dashpay/dash/pull/1675 (work in progress)

Before testing:

• Make sure you made a backup of you mainnet datadir somewhere or at least a backup of wallet.dat/dash.conf/masternode.conf;
• Remove testnet3 folder, old testnet is not compatible anymore, you need to sync from scratch.

What/how to test:

• DIP0001 is already active on testnet, so it’s capable of handling 2Mb blocks now and have lower fees. Send some transactions but please spam responsibly 
• InstantSend fix is also activated, so InstantSend is enabled on testnet, give it a try;
• Try mixing too, let’s see how it works now;
• Run a masternode or two, make sure it is paid;
• Create some proposals and/or up/down-vote some of them (remember, you need a masternode to vote but you don’t need a masternode to submit a proposal).

What else you can do:

• Report serious issues (crashes/hangs/GUI glitches) : https://github.com/dashpay/dash/issues/new
• Participate in translations : https://www.dash.org/forum/threads/12-2-translations.17122/

Sentinel : https://github.com/dashpay/sentinel/tree/core-v0.12.2.x

NOTE: Make sure you pulled Sentinel from core-v0.12.2.x branch and changed network to testnet in sentinel.conf. If you already have a mainnet masternode on the same server, do NOT run testnet masternode in the same datadir as your mainnet masternode (i.e. .dashcore). Create new folder specifically for testing (e.g. .dashcore_test) and make sure you use -datadir= cmd-line parameter for dashd and dash-cli. You’ll also need a separate crontab line for testnet Sentinel. If you are not 100% sure what you are doing, I’d recommend setting up a new machine/instance for testing purposes only instead of reusing your mainnet server.
