 - compiler-rt, libcxx, libcxxabi, and libunwind were updated to LLVM 19.1.6.
   (#22937, #22994, and #23294)
-- The Wasm nontrapping-fptoint feature has been enabled by default. clang will
-  generate nontrapping (saturating) float-to-int conversion instructions for
-  C typecasts. This should have no effect on programs that do not have
-  undefined behavior but if the casted floating-point value is outside the range
-  of the target integer type, the result will be a number of the max or min value
-  instead of a trap. This also results in a small code size improvement because
-  of details of the LLVM IR semantics. This feature can be disabled in clang with
-  the -mno-nontrapping-fptoint flag. (#23007)
-- The `WASM_BIGINT` feature has been enabled by default. This has the effect that
-  Wasm i64 values are passed and returned between Wasm and JS as BigInt values
-  rather than being split by Binaryen into pairs of Numbers. (#22993)
+- The default Safari version targeted by Emscripten has been raised from 14.1
+  to 15.0 (the `MIN_SAFARI_VERSION` setting) (#23312). This has several effects:

+  - The `BULK_MEMORY` feature is enabled by default. `memory.copy` and
+    `memory.fill` instructions are used in the implementation of C `memcpy` and
+    `memset`, and Clang may generate them elsewhere (#22873). It can be
+    disabled with the `-mno-bulk-memory` flag.
 - When using `-sMODULARIZE` we now assert if the factory function is called with
   the JS `new` keyword.  e.g. `a = new Module()` rather than `b = Module()`.
   This paves the way for marking the function as `async` which does not allow
