I would like to try this, but on my Mac I get: ``` error[E0308]: mismatched types --> crates/epaint/src/text/font.rs:96:63 | 96 | freetype::ffi::FT_Get_Next_Char(raw_font, charcode, &mut self.gindex) | ------------------------------- ^^^^^^^^ expected `u64`,...

We haven't officially decided what our minimum supported Ubuntu is (see https://github.com/rerun-io/rerun/issues/1346), but Ubuntu 18.04 was released in 2018 and will loose standard support [on April 2023](https://wiki.ubuntu.com/Releases), so I'm leaning...

I've created an issue to track the next release: https://github.com/rerun-io/rerun/issues/1386

I think we can switch from `zstd` to [`lz4_flex`](https://github.com/pseitz/lz4_flex). To get the benefits we must first remove `zstd` from our `puffin` dependency: * https://github.com/EmbarkStudios/puffin/issues/131 **EDIT:** * https://github.com/EmbarkStudios/puffin/pull/135 * https://github.com/rerun-io/rerun/pull/2112

Current state on my M1 MacBook Pro ``` sccache --stop-server && rm -rf /Users/emilk/Library/Caches/Mozilla.sccache && sccache --start-server cargo clean && cargo build --timings -p rerun ``` 2m 12s

This halves compilation times for users only using the `rerun` crate as a logging library: * https://github.com/rerun-io/rerun/pull/2183

Things has improved - `cargo clean && cargo build --timings -p rerun` on my M1 MacBook Pro: 78.8s and 353 dependencies

We already have a fixed version number. Each encoded message is prefixed with `RRF0` and four zero-bytes.
