+These are release notes for the Swift 0.6 release. Items
+listed below are changes since Swift 0.5 - both enhancements
+and known issues.
+
+Swift 0.6 is built from Swift SVN r2177 and CoG SVN r2127.
+(0.5 was swift r1783 cog r1962)
+
+A more detailed change log can be found in CHANGES.txt in the distribution
+tarball.
+
+This release contains the following new experimental features:
+
+* job replication
+
+When a job has been queued on a site for too long, Swift can resubmit the
+job (possibly to a different site). Replication is controlled by
+replication.* parameters in the swift.properties configuration file. Those
+parameters are documented inline in that configuration file.
+
+* cog coasters
+
+Swift can use cog coasters which allow a pilot job to be submitted to
+a site which will pull in actual Swift jobs for execution. This has
+several advantages:
+ .  when a large number of jobs need to be submitted, using coasters
+    reduces the job submission overhead in (eg) GRAM to one job per
+    worker node. 
+ .  once a node is allocated to a coaster, it can be used to run
+    many swift jobs, avoiding the need for each job to be queued
+    separately.
+
+* rate limiting for bad sites
+
+Previous versions of Swift would try to ensure that each site had at
+least two jobs queued or running at once, no matter how poorly performing.
+Swift v0.6 will substantially reduce the number of jobs sent to poorly
+performing sites; when a site score goes below 1 (job at once) then
+Swift will delay sending more jobs to that site, with the delay increasing
+exponentially as the score lowers.
