Approximately the 15th of September there will be a scheduled protocol upgrade on the Monero network. Most pools have upgraded or are in the process of upgrading, but some have not upgraded yet.
If they don't upgrade before the scheduled protocol upgrade they will get booted off the network. As a result you will miss out on revenue if you are mining on these pools. Thus, if you are mining on one of the pools that hasn't upgraded yet or hasn't scheduled an upgrade, please contact your pool owner as soon as possible and urge them to upgrade. Alternatively, you can switch to a pool that is on the right version.
