What's New in This Release: [ read full changelog ]

Security fixes:
· Use POSIX poll() on systems where available. This avoids a design flaw in select(); it supports no more than FD_SETSIZE descriptors.

Core libraries:
· Fixed EINTR handling in process-wait and when reading from file ports.
· Bugfix for irregex (#686). Note: although irregex.scm now says version 0.9.2, the version is actually 0.8.3 plus a few backported patches.
· Fixed problem in "make-pathname" that returned an absolute path if given a relative one without a directory argument.
· On 64-bit systems the feature identifier "64bit" is registered.

Compiler:
· Fixed various bugs in the type database.
· Bugfixes and improvements in the scrutinizer.
· In the flow-analysis pass, type-matching of combinations of "list"/"list-of" types has been made more reliable.

Syntax expander:
· Make macro-renamed defines in begin bodies (inside modules) visible to later forms. (#944).

Runtime system:
· Fixed incorrect code in the foreign argument conversion for "unsigned-integer64" (#955).

Core tools:
· The runtime linker path for compiled executables was not set correctly on FreeBSD systems.
· Fix install-extension breakage when the second arg contains pairs (SRC DST).

Build system:
· Prevent rebuilding of buildversion.scm on every make(1) on Windows.
