+ This file lists the significant user-visible changes between releases
+ of BLCR, including main features and bug fixes.
+
++0.8.6_b4
++-----------
++October 20, 2014
++Bug fix and expanded-support release.
++ - Relative to the previous Beta:
++ + Can now parse Debian Jessie kernel naming (3.x-y vs 3.x.y).
++ Hopefully for real this time!
++ + Correct operation confirmed with 3.17.x kernels
++ - Testing is now "sufficient" for release.
++
++0.8.6_b3
++-----------
++October 6, 2014
++Bug fix and expanded-support release.
++ - Relative to the previous Beta:
++ + Fix compilation problems with recent ARM kernels
++ + A couple minor bug fixes
++ + Can now parse Debian Jessie kernel naming (3.x-y vs 3.x.y).
++ + autogen.sh now supports recent automake versions
++ - Testing on x86, x86-64, ppc and ppc64 now "sufficient" for release.
++
++0.8.6_b2
++-----------
++September 29, 2014
++Bug fix and expanded-support release.
++ - Relative to the previous Beta:
++ + Fix compilation problems with recent PPC/PPC64 kernels
++ - Testing on CPUs other than x86-64 remains "thin".
++ - The issue with Debian Jessie kernel naming remains UNresolved.
++
++0.8.6_b1
++-----------
++September 19, 2014
++Bug fix and expanded-support release.
++ - This release adds support for "vanilla" Linux kernels up to 3.16,
++ and has been tested with x86-64 3.x kernels from several popular
++ distributions.
++ - Testing on other CPUs will precede release of the final 0.8.6.
++ - This release fixes the following user-visible bugs and "issues"
++ + Fix bug 3142 - stopped.st timeout on many recent kernels
++ The problem would manifest as a failure of the stopped.st test
++ in "make check" on kernels containing the fix for CVE-2013-0871.
++ + Fix bug 2620 - /proc/PID/exe not restored on restart
++ The fix has been known since Dec 2009, but had unintentionally
++ never been applied to the 0.8.x release branch.
++ + Fix support that was broken by recent "RHEL6" kernels (such as
++ 2.6.32-431.23.3.el6.x86_64).
++ + Fix possible deadlock in pid-restore code
++ - This release is known NOT to work with Debian Jessie kernels due
++ to their kernel naming scheme (3.x-y) which BLCR's configure logic
++ does not recognize. This should be fixed in the final 0.8.6.
