+These are release notes for the Swift 0.4 release. Items
+listed below are changes since Swift 0.3 - both enhancements
+and known issues.
+
+*** Fixed data channel reuse behavior - this was broken in Swift 0.4 for
+ a number of sites.
+
+*** String literals now use \ as escape character - for example, use \"
+ to insert a quote into a string literal. Where \ was previously used
+ in a string literal, it is now necessary to escape it as \\
+
+ Use of quotes in string literals is not fully implemented, however,
+ so attempts to use it are likely to cause problems.
+
+*** Logging performance improvement in wrapper.sh
+
+*** The WeightedHost scheduler now has a lower bound (of -10)
+ on scoring to reduce the effect of penalising a host in the case of a
+ large number of transient errors. Previously, a large number of
+ transient errors would push the score so low that the score would
+ take far too long to return to a more appropriate value.
+
+*** Unused lrc field in site catalog removed.
+
+*** url field in site catalog execute element is now optional.
+
+*** jobmanager attribute to execution element in sites.xml does not work
+ when used with provider="gt2". Such execution elements can be expressed
+ using the jobmanager element syntax instead.

+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 features:
+
+* job replication (experimental)
+
+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 (experimental)
+
+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.
+
+* more compile time type checking
+
+More type checking is done at compile time. This will catch some errors at the
+start of execution which would previously have been detected later on in a run,
+and will give more useful error messages.

+These are the release notes for Swift 0.7
+
+More information about Swift can be found at http://www.ci.uchicago.edu/swift/
+
+Swift 0.7 is built from Swift SVN r2318 and cog SVN r2255.
+
+The following are significant changes since Swift 0.6 was released.
+
+Language changes:
+* readData2 procedure allows reading of data from a file in a format similar
+ to that used by the external mapper. This can sometimes be easier and more
+ expressive than using the plain readData format. See:
+ http://www.ci.uchicago.edu/swift/guides/userguide/procedures.php#procedure.readdata2
+* Empty statements are no longer allowed in SwiftScript programs.
+* A simpler syntax has been introduced for application procedures. The
+ previous syntax will continue to work for a number of future releases.
+ The new syntax is shown here:
+ http://www.ci.uchicago.edu/swift/guides/userguide/language.php#procedures.atomic
+
+Coasters:
+* Coasters can now transfer files. This can be used when there are a
+ large number of small files to transfer during a run. See:
+ http://www.ci.uchicago.edu/swift/guides/userguide/coasters.php
+* A large amount of testing and bugfixing on the coaster code should make
+ runs with coasters substantially more reliable.
+
+Configuration changes:
+* Swift will find executables on the remote system $PATH if no explicit
+ path is specified for an application executable in tc.data
+* Configuration files in the ~/.vdl2 directory are now ignored. Previously,
+ attempting to use a ~/.vdl2 configuration file would give an error message.
+
+Replication:
+* The expected queue time for the first job executed is now guestimated for
+ replication purposes, so that job can be replicated if necessary.
+ Previously, the first job would never be replicated as there was
+ insufficient information to estimate its expected queue time.
+
+Minor bugfixes:
+* Uninitialised state was missing from list of known states in runtime
+ ticker, causing it to appear at the end of status list rather than
+ its more natural position at the start.
+* The stageout destination directory is created using the same destination
+ host and provider as the actual stageout transfer. Previously, the
+ stageout directory was always created locally, which was incorrect
+ when using remote stageout URLs.
+* Better walltime handling to work with more LRM backends in GRAM
+
+Packaging:
+* Swift is now available in VDT-friendly pacman form to facilitate use
+ alongside the OSG software stack.

+These are the release notes for Swift 0.8
+
+More information about Swift can be found at http://www.ci.uchicago.edu/swift/
+
+Swift 0.8 is built from Swift SVN r2448 and cog SVN r2261
+
+The following are significant changes since Swift 0.7 was released:
+
+Log plotting:
+ * The swift log-processing package is now included in the release. This
+ can be used to plot graphs of Swift logs using the swift-plot-log
+ command:
+
+ $ swift-plot-log first-200901010000-abcdefg.log
+
+ which will create a report in report-first-200901010000-abcdefg/index.html
+
+Execution:
+ * Some job execution systems do not set the initial job working directory
+ as specified by Swift. Previously Swift was unable to execute on such
+ systems. As of 0.8, Swift sets the initial job working directory in a
+ more robust fashion. This problem commonly affected OSG sites running
+ Condor.
+
+ * Application success/failure status can now be taken from the CoG
+ provider layer, instead of using success/failure files on the remote
+ file system. This can reduce the load on the remote file system, but
+ does not work with all job execution mechanisms. Specifically, this
+ mechanism will not work with GRAM2 or clustering.
+
+Local execution:
+ * A deadlock caused when jobs output large amounts of data to stderr has been
+ fixed.
+
+Commandline client:
+ * A number of error messages have been improved.
+ * Console output is much less verbose: the progress ticker appears more often,
+ and individual application start and end messages are no longer shown. This
+ improves the quality of console output when jobs are executed at a high rate.
+
+Language:
+ * Handling of assignment statements in declarations and out of declarations
+ has been made more homogenous. Previously, some assignments could only
+ be made in a declaration statement (such as assigning arrays); and some
+ assignments could only be made away from a declaration statement (such as
+ expressions whose values were computed by some slow process). These two
+ forms of assignment should now be interchangeable.
+
+ * Mapper parameters can now be results of slow computations, rather than
+ needing to be known by the time that declarations are first encountered.
+ This remedies previous unintuitive behaviour.

+These are the release notes for Swift 0.9
+
+More information about Swift can be found at http://www.ci.uchicago.edu/swift/
+
+Swift 0.9 is built from Swift SVN r2860 and cog SVN r2388
+
+The following are significant changes since Swift 0.8 was released:
+
+User interface
+==============
+
+*** Added console text interface to provide live information about swift
+ runs, which can be enabled with the -tui commandline parameter
+
+*** when replication is enabled, swift will locally kill jobs that have
+ run for twice their specified walltime
+
+Execution modes
+===============
+
+*** Support for Condor-G submissions, by setting a job specification attribute
+ of "grid" and specifying a gridResource attribute containing the string
+ to be placed into the Condor-G grid_resource classad.
+
+*** Support for submissions to a local condor pool
+
+*** Coasters: substantial ongoing development work
+
+Configuration parameters
+========================
+
+*** Environment variable SWIFT_EXTRA_INFO, when set in an environment profile,
+ is executed with the result being recorded in wrapper logs. This allows
+ arbitrary information about the remote environment to be gathered and
+ returned to the submit side.
+
+*** New configuration option wrapper.invocation.mode, specifiable either
+ globally in the configuration file or per-site as a profile key,
+ that configures whether wrapper script invocations are made with an
+ absolute path (as was the behaviour in Swift 0.8) or with a relative
+ path (as was behaviour in previous versions of Swift).
+
+*** New profile key coasterWorkerMaxwalltime - a coaster parameter to
+ explicitly set worker maxwalltime, overriding the default computation
+ based on job walltimes. this should be useful when it is desirable
+ to specify worker parameters based on the known properties of the
+ target queue rather than on properties of the jobs to be executed
+ inside coasters.
+
+*** New profile key coasterInternalIP parameter that allows the IP address
+ used by coaster workers to communicate to the coaster head job to be set
+ explicitly. This can be used when running on a cluster which an internal
+ network which cannot access the IP address that the head node picks
+
+*** configuration property ticker.disable to disable runtime ticker display
+
+New commands
+============
+
+*** The log-processing code, primarily exposed as the swift-plot-log command,
+ has been merged into the main Swift release, rather than being a separate
+ download.
+
+*** There is a new command swift-osg-ress-site-catalog which will generate
+ a site catalog based on data gathered from OSG's ReSS information
+ system. This can be used by OSG users to easily generate a large number
+ of site catalog entries for sites that are likely to work.
+
+Language changes
+================
+
+*** Procedure invocations can be made in any expression context now, rather
+ than only directly in an assignment.
+
+*** Mappings can now be made in any declaration, whether it has an assignment
+ or not. Previous a procedure call assignment and a mapping could not be
+ made in the same statement.
+
+*** Handling of [*] and . has changed. [*] has been broken for several
+ Swift releases, but now has some approximation of its former behaviour,
+ in a cleaner implementation.
+ [*] is now an identity operation, that is array[*] == array.
+ The structure access operator . can now take an array on the left
+ hand side. In situations where a[*].img was used, it is permissible
+ to continue to write a[*].img, or to write a.img - both of these will
+ return an array of img elements.
+
+*** Tighter type checking on app blocks. Primitive types and arrays of
+ primitive types are permitted. Other types are prohibited.
+
+*** Arrays of primitive types can be passed to app blocks, and will be
+ expanded into multiple command-line parameters, one parameter per
+ array element.
+
+*** != operator had been broken forever. It works now.
+
+*** output of trace() is changed for non-primitive datasets:
+
+ * Array handling:
+ Previous to this, trace would show the internal Java object representation
+ of an arrays, which is fairly useless for a user. This commit makes
+ trace show more about the array, and only emit the trace when the array
+ is closed.
+
+ * Other datasets:
+ Trace will wait for those datasets to be closed, and emit their default
+ string representation (including the variable name and path used in
+ SwiftScript)
+
+*** loop condition in iterate statements can now refer to variables declared
+ within the iteration body (this was bug 177)
+
+*** Mappings can now be made in any declaration, whether it has an assignment
+ or not.
+
+*** strsplit function which will split the input string based on separators
+ that match the given pattern and return a string array.
+
+
+Deprecations and removal of old functionality
+=============================================
+
+*** Removed support for .dtm file extension which was deprecated in Swift 0.4
+
+Internal changes
+================
+
+*** The wrapper.sh and seq.sh scripts that are deployed to remote sites to
+ help with execution have been renamed to more Swift specific names, to
+ avoid collision with user-supplied files of the same name. The new names
+ are _swiftwrap and _swiftseq
+
+*** Recompilation will happen if a .kml file was compiled with a different
+ version of Swift to the version being invoked. This is in addition to the
+ existing behaviour where a .swift file will be recompiled if it is newer
+ than the corresponding .kml file.
+
+*** Added a throttling parallelFor and changed the swift foreach underlying
+ implementation to it. The throttling parallelFor limits the number of
+ concurrent iterations allowed, which should allow swift to scale better
+ in certain cases. This is controlled by the configuration property
+ foreach.max.threads
+
+*** Default JVM heap size is now 256M
