Matthew Flatt commit bf4fc2574c06132fece7342219fe6ea589e42f6d fix syntax colorer for #true and #false commit 99df8e126790077c11b4363a273ebf777bff8514 allow internal definitions in `when', `unless', `cond, `case', `match' commit 15302dc844ecf931145f895677cc8eb765b69960 adjust futures to decouple blocked futures from worker threads which required adding a notion of "lightweight continuation" to the runtime system, where a lightweight continuation involves only frames from JIT0generated code (so that details of the stack layout are known, for example) Mike Sperber commit 38cf78e213ee8f246ce322becb419aaed6ec2391 Allow specifying arbitary expressions in a signature declaration.

Adding one armed check-error to teaching languages. commit d17deb5fef8342e2dc25b6ddd027bd71d6373a8f Adding hash table functions to ASL commit 407dcee206678785b4b87bb513d7ba5f55ad8ab5 Adding match to ASL commit 347e946548c26bd51b682284816aa7f6f34b2d92 Adding WebSocket support Stevie Strickland commit ec0711bf4996dde06ecddbc8fcb95f44987a6915 Add chaperone contract-related properties. * Flat contracts are chaperone contracts, and chaperone contracts are (proxy) contracts. * Check in chaperone contracts that a chaperone (or chaperone-friendly value) is indeed returned. Ryan Culpepper commit 5a8d2f010e9e7858ff8c32ffadf73adac11cd98a added data/gvector, docs (need tests) commit d7a87c79e0211071fecb8474e6f7f66317b089d4 Merged changes to syntax/parse Changed backtracking algorithm, runtime representations - syntax classes, ~describe no longer implicitly commit - ~describe no longer delimits effect of cut Added keyword & optional args for stxclasses Added ~do and #:do, ~post, ~commit and #:commit, ~delimit-cut and #:no-delimit-cut Added syntax/parse/debug, syntax/parse/experimental/* - expr/c for contracting macro sub-expressions moved from syntax/parse to syntax/parse/experimental/contract - syntax class reflection (~reflect, ~splicing-reflect) - eh-alternative-sets (~eh-var) - provide-syntax-class/contract (only for params, not attrs so far) Changed ~fail to not include POST progress (#:fail still does) old (~fail _) is now (~post (~fail _)) Made msg argument of ~fail optional Removed generic "repetition constraint violated" msg Removed atom-in-list stxclass Removed unnecessary datum->syntax on cdr of pair pattern massive improvements to long-list microbenchmarks Optimization: integrable syntax classes (id, expr, keyword) need better measurements Optimization: ad hoc elimination of head/tail choice point for (EH ... . ()) patterns Added unstable/wrapc (proc version of expr/c) Robby Findler commit 5e01ac55373d2987410da7d95f26f42535cfae3b added a pinhole property to images commit 561ac12a91e02fbc298272cc97d96e00d92f98ae got started on the ->i parser Sam Tobin-Hochstadt commit 0635fc6d7542ea412e4586ca6ca051fdd2d91adb Create data/ collection. - Initially populated with queues, skip-lists, and interval-maps from unstable/ - Tests in tests/data, docs in data/scribblings Jens Axel Søgaard commit 64c3a98e45bda91b39eb811456ab409b72f0936e Added triangle/sss, triangle/ass, triangle/sas, triangle/ssa, triangle/aas, triangle/asa, and, triangle/saa.
