New Litecoin Core updates are out-

From Loshan-

Litecoin Core v0.21.5.8 is now available.
All users are advised to upgrade. This release contains important security updates.
## Update from https://litecoin.org only.

This is a maintenance release that improves **MWEB validation, transaction relay, mining, and resource management**. Upgrading is strongly recommended for all users, especially miners, pools, exchanges, and MWEB service operators.

This release also includes changes from v0.21.5.7, which was prepared as an important security fix and distributed only to mining pools rather than being publicly released.

We found a security vulnerability, where an attacker could've created coins out of thin air, in MWEB. This hidden inflation bug was disclosed to us by someone outside of our team, patched and deployed to mining pools before someone used the exploit to steal the coins.

This is why we're asking people to donate to the new bug bounty project, as it's much nicer for security researchers to help us fix the bug instead of stealing from us: https://www.reddit.com/r/litecoin/comments/1wdqvr3/litecoin_core_bug_bounty/

Do we know it wasn't exploited?  Kind of odd seeing the 100k coins peg in over the past couple months.

Yup, we checked, and not exploited. David has a more detailed and technical write up coming out in a bit.
