+## Rust Compiler Performance Triage
+
+* [2020-09-21](https://github.com/rust-lang/rustc-perf/blob/master/triage/2020-09-21.md):
+  2 Regressions, 5 Improvements, 4 Mixed
+
+This was the first week of semi-automated perf triage, and thank goodness:
+There was a lot going on. Most regressions are either quite small or already
+have a fix published.
+
+[#72412](https://github.com/rust-lang/rust/issues/72412) is probably the most
+interesting case. It fixes a pathological problem involving nested closures by
+adding cycle detection to what seems to be a relatively hot part of the code.
+As a result, most users will see a slight [compile-time
+regression](https://perf.rust-lang.org/compare.html?start=2c69266c0697b0c0b34abea62cba1a1d3c59c90c&end=fdc3405c20122fd0f077f5a77addabc873f20e4c&stat=task-clock)
+for their crates.
+
+See the [full report](https://github.com/rust-lang/rustc-perf/blob/master/triage/2020-09-21.md) for more.
+
+## Approved RFCs
+
+Changes to Rust follow the Rust [RFC (request for comments) process](https://github.com/rust-lang/rfcs#rust-rfcs). These
+are the RFCs that were approved for implementation this week:
+
+* [[RFC]: Portable SIMD Libs Project Group](https://github.com/rust-lang/rfcs/pull/2977)
+* [Establish a new error handling project group](https://github.com/rust-lang/rfcs/pull/2965)
+

+# Quote of the Week
+
+> Sometimes you don't *want* the code to compile. The compiler's job is often to tell you that your code doesn't compile, rather than trying to find some meaning that allows compiling your code.
