[racket-dev] Release Announcement for v6.1.1

For me:

  * Added the drracket/check-syntax library to facilitate check
syntax-like behavior in other IDEs

  * Redex: explained the benchmark programs added a conditional-form
to metafunctions

  * 2htdp/image's notion of equality no longer considers an image's baseline.

  * Contracts: contract-stronger? is now more consistently useful and
contract error messages now admit the contract itself might be wrong
