This is *technically* a breaking change because we're now always sending data gzip compressed and people might not want that, but this will not break anyone's code so we'll release it as a minor knowing that it's an improvement. It's always been possible to swap the client off, but we weren't documenting how to do that exactly - this is now solved too.

There was a problem hiding this comment.
some SDKs provide a client config for that eg https://github.com/PostHog/posthog-js/blob/a3cc497d977298637155a2c15030f3fcfe1e613f/packages/types/src/posthog-config.ts#L1228-L1234
also remote config returns supportedCompression which then we know if the server supports gzip or not
not a blocker, as this is already the default behaviour for many SDKs, and PH Cloud supports gzip.
