 ## What's in 1.52.0 stable
 
-This release is fairly small, primarily containing stabilizations of various APIs in the standard library.
+The most significant change in this release is not to the language or standard
+libraries, but rather an enhancement to tooling support for Clippy.
 
-We have also closed out a long-standing [bug] in the Rust compiler. Previously, LLVM assumed that the program would make progress, and used this to optimize. This meant that certain constructs in safe Rust were removed or otherwise miscompiled, such as infinite loops (`loop {}`) or recursion which didn't terminate.
-
-In Rust 1.49.0, we landed a [partial fix] to this bug specifically targeting
-`loop {}`, but this fix brings an LLVM upgrade which avoids needing workarounds
-for these cases, fixing the larger class of bug.
-
-Clippy has also gained a significant usability improvement: it no longer shares
-its build cache with `cargo check`, which means that errors and warnings will be
-properly reported when running it after `cargo check`.

+Previously, running `cargo check` followed by `cargo clippy` wouldn't actually
+run clippy: the build caching in Cargo didn't differentiate between the two. In
+1.52, however, this has been fixed, which means that users will get the expected
+behavior independent of the order in which they run the two commands.
