Slick Morty

Overview

This release contains stability improvements and bug fixes in the networking stack.

This corrects an issue where nodes lost track of the head of the chain and required rebooting to rejoin the medalla network.

Details

• a1f9769 Update to the latest libp2p - bug fixes including extra peer disconnect notifications (#1482)
• 08a31c5 Bug fix to correctly disconnect and monitor peers that connect beyond our max peer limit (#1484)
• 04e4389 Updates gossipsub to prevent O(N) lookups for duplicates and prevents the possibility of opening excessive substreams. This reduces CPU overhead of nodes. (#1490)
• cbfae87 Updates discv5 to handle UDP port binding inside lighthouse as well as upgrading logs inside lighthouse to notify users if the address/port could not be bound to. (#1496)

Binaries

Binaries are supplied for two platforms:

• x86_64-unknown-linux-gnu: AMD/Intel 64-bit processors (most desktops, laptops, servers)
• aarch64-unknown-linux-gnu: 64bit ARM processors (Raspberry Pi 4)

Additionally there are two variants:

• fast: uses modern CPU instructions to provide the fastest signature verification times (may cause Illegal instruction error on older CPUs)
• portable: approx. 20% slower, but should work on all modern 64-bit processors.
