 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.
