Non mandatory update

some users are in split, so we publish this release for unify chain:

[CODE]: We updated the checkpoints to unify chain

we made a new boostrap for users that prefer not to install new version. they could use the bootstrap in windows, mac or linux.

For use, you must delete all in your chain folder and let only the following folders/files:

• backups
• wallet.dat
• Reecore.conf
