  TinkerPop 3.2.5 (Release Date: NOT OFFICIALLY RELEASED YET)
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
 +* De-registered metrics on Gremlin Server shutdown.
 +* Added "help" command option on `:remote config` for plugins that support that feature
in the Gremlin Console.
 +* Allowed for multiple scripts and related arguments to be passed to `gremlin.sh` via `-i`
and `-e`.
 +* Added various metrics to the `GremlinGroovyScriptEngine` around script compilation and
exposed them in Gremlin Server.
 +* Moved the `caffeine` dependency down to `gremlin-groovy` and out of `gremlin-server`.
 +* Improved script compilation in `GremlinGroovyScriptEngine to use better caching, log long
compile times and prevent failed compilations from recompiling on future requests.
 +* Script compilation is synchronised.
 +* Script compilation times are placed in to logs.
 +* Failed scripts will not be recompiled.
 +* Scripts that take over 5 seconds to compile are logged as a warning.
+ * Added `cyclicPath().from().to().by()` support to `GraphTraversal`.
+ * Added `simplePath().from().to().by()` support to `GraphTraversal`.
+ * Added `path().from().to()` support to `GraphTraversal` so sub-paths can be isolated from
the current path.
+ * Added `FromToModulating` interface for use with `to()`- and `from()`-based step modulators.
+ * Added `Path.subPath()` which supports isolating a sub-path from `Path` via to/from-labels.
  * Fixed an `NullPointerException` in `GraphMLReader` that occurred when an `<edge>`
didn't have an ID field and the base graph supported ID assignment.
  * Split `ComputerVerificationStrategy` into two strategies: `ComputerVerificationStrategy`
and `ComputerFinalizationStrategy`.
  * Removed `HasTest.g_V_hasId_compilationEquality` from process test suite as it makes too
many assumptions about provider compilation.

  ~~~~~~~~~~~~~~~~~~~
  
 +GremlinScriptEngine Metrics
 +^^^^^^^^^^^^^^^^^^^^^^^^^^^
 +
 +The `GremlinScriptEngine` has a number of new metrics about its cache size and script compilation
times which should
 +be helpful in understanding usage problems. As `GremlinScriptEngine` instances are used
in Gremlin Server these metrics
 +are naturally exposed as part of the standard link:http://tinkerpop.apache.org/docs/current/reference/#_metrics[metrics]
 +set. Note that metrics are captured for both sessionless requests as well as for each individual
session that is opened.
 +
 +See: https://issues.apache.org/jira/browse/TINKERPOP-1644[TINKERPOP-1644]
 +
 +Gremlin Console Scripting
 +^^^^^^^^^^^^^^^^^^^^^^^^^
 +
 +The `gremlin.sh` command has two flags, `-i` and `-e`, which are used to pass a script and
arguments into the Gremlin
 +Console for execution. Those flags now allow for passing multiple scripts and related arguments
to be supplied which
 +can yield greater flexibilty in automation tasks.
 +
 +[source,bash]
 +----
 +$ bin/gremlin.sh -i y.groovy 1 2 3 -i x.groovy
 +$ bin/gremlin.sh -e y.groovy 1 2 3 -e x.groovy
 +----
 +
 +See: link:https://issues.apache.org/jira/browse/TINKERPOP-1653[TINKERPOP-1653]
 +
+ simplePath(), cyclicPath(), and path() support by()-, from()-, to()-modulation
+ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+ 
+ It is now possible to extract analyze sub-paths using `from()` and `to()` modulations with
respective, path-based steps.
+ Likewise, `simplePath()` and `cyclicPath()` now support, along with `from()` and `to()`,
`by()`-modulation so the cyclicity
+ is determined by projections of the path data. This extension is fully backwards compatible.
