Firo v0.14.7.0

INSTRUCTIONS

This is an optional but recommended release that introduces Receiver Address Privacy (RAP) addresses, an adaptation of BIP47 that supports sending Lelantus transactions for the notification transaction.

It also includes several performance improvements and bug fixes.

As always, backup your wallet prior to updating for safety.

• In certain edge cases, private balance are not available after restoring wallet from mnemonics. Fix underway.

Firo v0.14.2.3

INSTRUCTIONS

This is a mandatory upgrade for all versions prior to this release. Everyone must upgrade by block 336888 (14 January 2021).

As always, please backup your wallet prior to updating for safety!

This release renames the default data directory name to .firo and the zcoin.conf file to firo.conf. The rename process is opt-in and will not run unless explicitly set.

If you are using Firo-QT, read the migration guide here: https://firo.org/guide/firo-migration-guide.html

If you are using the daemon, start it with:
./firod -migratetofiro

If you are using a custom data directory (-datadir), please migrate manually by renaming zcoin.conf to firo.conf and/or your data directory.

Remember that many scammers will be out to offer help to you to help you migrate so don't accept unsolicited private messages even if it appears from a trusted person (in fact none of the core team members will ever message to you first).

We will never send out private messages on wallet updates.

CHANGELOG

• Reinstated Sigma banlist in Lelantus #964
• Update copyright info #949

OPEN ISSUES

• GUI notification to deal with Lelantus joinsplit transactions when spork is activated.
