Candidate 9-24-2021
See changelog:
It is exactly 1 year since L4D2's Last Stand Update was released.
This update is a huge re-organization with modest re-writes and a lot more fixes.
Anyone may test these and report issues. Valve will be kept up-to-date and ship when they can.
Note: Customization scripts #13 are pending, but bandaids SirPlease/L4D2-Competitive-Rework#320 have been applied with competitive config's simple removal of "anv_versus.nut".
