From: Peter Bex Subject: [Chicken-announce] [ANN] CHICKEN 4.12.0 has been released Date: Sun, 19 Feb 2017 13:57:16 +0100 User-agent: Mutt/1.5.23 (2014-03-12)

Dear CHICKEN users, We are pleased to announce the immediate availability of CHICKEN 4.12.0 at the following URL: https://code.call-cc.org/releases/4.12.0/chicken-4.12.0.tar.gz This tarball has the following SHA256 checksum: 605ace459bc66e8c5f82abb03d9b1c9ca36f1c2295931d244d03629a947a6989 This is mostly a bugfix release with a relatively small number of changes, considering our focus is on CHICKEN 5. However, these changes fix quite a few very important bugs. The most important changes since 4.11.0 are three security fixes, namely CVE-2016-6830, CVE-2016-6831 and CVE-2016-9954. We have updated our copy of Irregex to upstream version 0.9.6 which fixes the aforementioned security issue CVE-2016-9954 and a bug with how "bow" is handled in irregex-fold. There are also three notable bug fixes in our runtime and compiler. One fixes how "parameterize" interacts with continuations (#1336), another prevents crashes when a garbage collection is invoked while running an FFI callback (#1337) and another fixes re-entering functions that are compiled to C loops after returning from a garbage collection (#1317), which could lead to endless loops and even incorrect computations. For a full list of the changes since 4.11.0, see the NEWS file: https://code.call-cc.org/releases/4.12.0/NEWS Kind regards, The CHICKEN Team
