+ * enhancement: extended package prefix syntax <pkgname>::<form-in-package>
+ which allows specifying name of the default interning package for the
+ whole form.
+ * enhancement: when *READ-EVAL* is true, arrays with element type other than
+ T can be printed readably using #.-based syntax. (Thanks to Robert Brown)
+ * enhancement: MAKE-ALIEN signals a storage-condition instead of returning a
+ null alien when malloc() fails. (lp#891268)
+ * enhancement: SB-EXT:PRINT-UNREADABLY restart for PRINT-NOT-READABLE
+ conditions can be conveniently accessed through function with the same
+ name, analogously to CONTINUE.
+ * enhancement: SB-EXT:*SUPPRESS-PRINT-ERRORS* can be used to suppress errors
+ from the printer by type, causing an error marker to be printed instead.
+ (Thanks to Attila Lendvai)
+ * enhancement: BACKTRACE and DESCRIBE now bind *PRINT-CIRCLE* to T, and
+ generally behave better when errors occur during printing.
+ * enhancement: the test runner now takes a --report-skipped-tests argument
+ to report the individual tests skipped as well as the number of skipped
+ tests.
+ * enhancement: undefined functions now appear in backtraces as ("undefined
+ function") instead of ("bogus stack frame") on x86oids.
+ * enhancement: detected deadlocks no longer cause stderr to be spammed, and
+ deadlock errors are reported in an easier-to-decipher manner.
+ * enhancement: DESCRIBE on type designators reports the expansion in more
+ cases.
+ * enhancement: SBCL now provides either an explicit :BIG-ENDIAN or
+ :LITTLE-ENDIAN in *FEATURES*, instead of :BIG-ENDIAN being implied by lack
+ of the :LITTLE-ENDIAN feature. (Thanks to Luís Oliveira, lp#901661)
+ * enhancement: better disassembly of segment-prefixes on x86 and other
+ instruction prefixes (e.g. LOCK) on x86 and x86-64.
+ * optimization: FIND and POSITION on bit-vectors are orders of magnitude
+ faster (assuming KEY and TEST are not used, or are sufficiently trivial).
+ * optimization: SUBSEQ on vectors of unknown element type is substantially
+ faster. (lp#902537)
+ * optimization: specialized arrays with non-zero :INITIAL-ELEMENT can
+ be stack-allocated. (lp#902351)
