This is a minor release, mostly consisting of bugfixes in network-related packages. It also includes improvements to the Emacs smalltalk-mode, fixes for platforms with 113-bit long doubles, and fixes to the C binding mechanism. The parser for the Squeak/Pharo format was updated.
Many bugs were fixed. gst-package supports downloading from HTTPS URLs. You can optionally specify a timeout when waiting on a Semaphore. SCGI support was added in the Swazoo Web server. Virtual machine performance was improved on x86-64. Starting from these release, bundled libraries (libsigsegv, libffi, libltdl) are never preferred over pre-installed libraries.
