Ok, so here's what we have so far: - Typed Racket and the racket/contract library generate code with lower overhead, speeding up typed/untyped interaction in a number of gradual typing programs we studied.
- Macros written using `syntax-parse` automatically emit more accurate error messages. - The contract profiler captures costs from more contract combinators, including all those in the main distribution. - Iteration over hash tables using `in-hash`, `in-hash-pairs`, `in-mutable-hash` and `in-mutable-set` have improved performance, up to twice as fast on microbenchmarks. - The Racket optimizer detects many more optimization opportunities, including when variables always hold numbers. - The `db` library supports multi-result statements in MySQL. - The `net/dns` library supports SRV records.
