This release changes the default allocator (on linux/x86_64) to be `jemalloc`. In tests, jemalloc proves to use less memory without noticeable impacts on CPU utilization or latency. This change also includes dependency updates, including an update of Rust to v1.56.0. --- * build(deps): bump tower from 0.4.9 to 0.4.10 (linkerd/linkerd2-proxy#1320) * Adopt Rust edition 2021 (linkerd/linkerd2-proxy#1295) * Use jemalloc (linkerd/linkerd2-proxy#1321) * Disable incremental compilation in CI (linkerd/linkerd2-proxy#1322) * build(deps): bump h2 from 0.3.6 to 0.3.7 (linkerd/linkerd2-proxy#1324) * build(deps): bump http-body from 0.4.3 to 0.4.4 (linkerd/linkerd2-proxy#1325) * build(deps): bump hyper from 0.14.13 to 0.14.14 (linkerd/linkerd2-proxy#1326)

In load tests, it appears that jemalloc is--perhaps unsurprisingly--more efficient than the alternatives. Specifically, jemalloc uses less memory and is more responsive to memory being released without substantially impacting latency or CPU usage. This is only enabled on `x86_64-unknown-linux-gnu`, as this is the only platform on which all tests pass, etc (per [gnzlbg/jemallocator][readme]).
