+
+== Internal Improvements

+* pr:15568[] replace `format_args` parser with upstream fork.
+* pr:15565[] implement `write_via_move` intrinsic for MIR eval.
+* pr:15571[] remove allocation on MIR eval memory write.
+* pr:15567[] ignore enum variants in analysis stats of MIR bodies.
+* pr:15575[] intern projections in MIR place.
