| * Fixed a severe bug where `LP_O_OB_P_S_SE_SL_Traverser` was not registered with `GryoMapper`. |
| * The future from `GremlinExecutor.eval()` is completed after the entire evaluation lifecyle is completed. |
| * Spark `Memory` uses `collect().iterator()` instead of `toLocalIterator()` to reduce noise in Spark UI. |
| * Added the `:remote console` option which flips the Gremlin Console into a remote-only mode where all script evaluation is routed to the currently configured remote, which removes the need to use the `:>` command. |
| * Added `allowRemoteConsole()` to the `RemoteAcceptor` interface. |
| * The `:remote` for `tinkerpop.server` now includes an option to establish the connection as a "session". |
| * Provided an implementation for calls to `SessionedClient.alias()`, which formerly threw an `UnsupportedOperationException`. |
| * Bumped to commons-collections 3.2.2. |
| * Fixed a bug where `OrderGlobalStep` and `OrderLocalStep` were not incorporating their children's traverser requirements. |
| * Fixed a compilation bug in `TraversalExplanation`. |
| * Fixed bug where a session explicitly closed was being closed again by session expiration. |
| * Improved the recovery options for `gremlin-driver` after failed requests to Gremlin Server. |

| * Bumped to Apache Groovy 2.4.6. |
| * Added the `gremlin-archetype-server` archetype that demonstrates |
| * Added the `gremlin-archetype-tinkergraph` archetype that demonstrates a basic project that uses TinkerGraph. |
| * Added `gremlin-archetype` module to house TinkerPop "examples". |
| * Fixed a condition where `ConnectionPool` initialization in the driver would present a `NullPointerException` on initialization if there were errors constructing the pool in full. |
| * Fixed a bug in the round-robin load balancing strategy in the driver would waste requests potentially sending messages to dead hosts. |
| * Added new Provider Documentation book - content for this book was extracted from the reference documentation. |
| * Fixed a bug where multiple "close" requests were being sent by the driver on `Client.close()`. |
| * Fixed an `Property` attach bug that shows up in serialization-based `GraphComputer` implementations. |
| * Fixed a pom.xml bug where Gremlin Console/Server were not pulling the latest Neo4j 2.3.2. |

| * Deprecated `ScriptElementFactory` and made the local `StarGraph` globally available for ``ScriptInputFormat``'s `parse()` method. |
| * Improved reusability of unique test directory creation in `/target` for `AbstractGraphProvider`, which was formerly only available to Neo4j, by adding `makeTestDirectory()`. |
| * Optimized memory-usage in `TraversalVertexProgram`. |
| * `Graph` instances are not merely "closed" at the end of tests, they are "cleared" via `GraphProvider.clear()`, which should in turn cleans up old data for an implementation. |
| * Expanded the Gremlin Server protocol to allow for transaction management on in-session requests and updated the `gremlin-driver` to take advantage of that. |
| * Greatly reduced the amount of objects required in OLAP for the `ReducingBarrierStep` steps. |

| [[release-3-1-1-incubating]] |
| === TinkerPop 3.1.1 (Release Date: February 8, 2016) |
| |
| * Made `GryoRecordReader` more robust to 0 byte record splits. |
| * Fixed a constructor/serialization bug in `LP_O_OB_S_SE_SL_Traverser`. |
| * Added a lazy iterator, memory safe implementation of MapReduce to `SparkGraphComputer`. |
| * Added `MapReduce.combine()` support to `SparkGraphComputer`. |
| * Bumped to Neo4j 2.3.2. |
| * Fixed Java comparator contract issue around `Order.shuffle`. |
| * Optimized a very inefficient implementation of `SampleLocalStep`. |
| * Reduced the complexity and execution time of all `AbstractLambdaTraversal` instances. |
| * `DefaultTraversal` has a well defined `hashCode()` and `equals()`. |
| * Added serializers to Gryo for `java.time` related classes. |
| * Integrated `NumberHelper` in `SackFunctions`. |
| * Deprecated `VertexPropertyFeatures.supportsAddProperty()` which effectively was a duplicate of `VertexFeatures.supportsMetaProperties`. |
| * The Spark persistence `StorageLevel` can now be set for both job graphs and `PersistedOutputRDD` data. |
| * Added to the list of "invalid binding keys" allowed by Gremlin Server to cover the private fields of `T` which get exposed in the `ScriptEngine` on static imports. |
| * Added `BulkDumperVertexProgram` that allows to dump a whole graph in any of the supported IO formats (GraphSON, Gryo, Script). |
| * Fixed a bug around duration calculations of `cap()`-step during profiling. |
| * It is possible to completely avoid using HDFS with Spark if `PersistedInputRDD` and `PersistedOutpuRDD` are leveraged. |
| * `InputRDD` and `OutputRDD` can now process both graphs and memory (i.e. sideEffects). |
| * Removed Groovy specific meta-programming overloads for handling Hadoop `FileSystem` (instead, its all accessible via `FileSystemStorage`). |
| * Added `FileSystemStorage` and `SparkContextStorage` which both implement the new `Storage` API. |
| * Added `Storage` to the gremlin-core io-package which providers can implement to allow conventional access to data sources (e.g. `ls()`, `rm()`, `cp()`, etc.). |
| * Bumped to Spark 1.5.2. |
| * Bumped to Groovy 2.4.5. |
| * Added `--noClean` option in `bin/process-docs.sh` to prevent the script from cleaning Grapes and HDFS. |
| * Execute the `LifeCycle.beforeEval()` in the same thread that `eval()` is executed in for `GremlinExecutor`. |
| * Improved error handling of Gremlin Console initialization scripts to better separate errors in initialization script I/O versus execution of the script itself. |
| * Fixed a bug in `Graph.OptOut` when trying to opt-out of certain test cases with the `method` property set to "*". |
| * Added another `BulkLoader` implementation (`OneTimeBulkLoader`) that doesn't store temporary properties in the target graph. |
| * Added option to allow for a custom `ClassResolver` to be assigned to a `GryoMapper` instance. |
| * Fixed a `SparkGraphComputer` sorting bug in MapReduce that occurred when there was more than one partition. |
| * Added `strictTransactionManagement` to the Gremlin Server settings to indicate that the `aliases` parameter must be passed on requests and that transaction management will be scoped to the graphs provided in that argument. |
| * Fixed a `NullPointerException` bug in `PeerPressureVertexProgram` that occurred when an adjacency traversal was not provided. |
| * Standardized "test data directories" across all tests as generated by `TestHelper`. |
| * Fixed a bug in Gremlin Server where error messages were not always being passed back in the `statusMessage` field of the `ResponseMessage`. |
| * Added validation for parameter `bindings` to ensure that keys were `String` values. |
| * Improved Transaction Management consistency in Gremlin Server. |
| * Added `FileSandboxExtension` which takes a configuration file to white list methods and classes that can be used in `ScriptEngine` execution. |
| * Deprecated `SandboxExtension` and `SimpleSandboxExtension` in favor of `AbstractSandboxExtension` which provides better abstractions for those writing sandboxes. |
| * Fixed a long standing "view merge" issue requiring `reduceByKey()` on input data to Spark. It is no longer required. |
| * Added `Spark` static object to allow "file system" control of persisted RDDs in Spark. |
| * Added a Spark "job server" to ensure that persisted RDDs are not garbage collected by Spark. |
| * Improved logging control during builds with Maven. |
| * Fixed settings that weren't being passed to the Gremlin Driver `Cluster` through configuration file. |
| * `Column` now implements `Function`. The modulator `by(valueDecr)` can be replaced by `by(values,decr)` and thus, projection and order are separated. |
| * Added `InputRDDFormat` which wraps an `InputRDD` to make it accessible to Hadoop and not just Spark. |
| * Added `AbstractSparkTest` which handles closing `SparkContext` instances between tests now that we support persisted contexts. |
| * Fixed a serialization bug in `GryoSerializer` that made it difficult for graph providers to yield `InputRDDs` for `SparkGraphComputer`. |
| * `SparkGraphComputer` is now tested against Gryo, GraphSON, and `InputRDD` data sources. |
| * `HadoopElementIterator` (for Hadoop-Gremlin OLTP) now works for any `InputFormat`, not just `FileInputFormats`. |
| * Added `Traverser.Admin.getTags()` which are used to mark branches in a traversal (useful in `match()` and related future steps). |
| * Fixed the `Future` model for `GiraphGraphComputer` and `SparkGraphComputer` so that class loaders are preserved. |
| * Added support for arbitrary vertex ID types in `BulkLoaderVertexProgram`. |
| * Deprecated `credentialsDbLocation` from `SimpleAuthenticator` in Gremlin Server. |
| * `TinkerGraph` has "native" serialization in GraphSON, which enables it to be a return value from Gremlin Server. |
| * Improved the ability to embed Gremlin Server by providing a way to get the `ServerGremlinExecutor` and improve reusability of `AbstractEvalOpProcessor` and related classes. |
| * Added `Authenticator.newSaslNegotiator(InetAddress)` and deprecated the zero-arg version of that method. |
| * `ProfileStep` is now available off of `Traversal` via `profile()`. To be consistent with `Traversal.explain()`. |
| * If no comparator is provided to `order()`, `Order.incr` is assumed (previously, an exception occurred). |
| * Fixed various Gremlin-Groovy tests that assumed `toString()`-able ids. |
| * Split TinkerPop documentation into different directories. |
| * Added `explain()`-step which yields a `TraversalExplanation` with a pretty `toString()` detailing the compilation process. |
| * Fixed a traversal strategy ordering bug in `AdjacentToIncidentStrategy` and `IncidentToAdjacentStrategy`. |
| * Made a number of changes to improve traversal startup and execution performance. |
| * Added support for 'gremlin.tinkergraph.graphLocation' to accept a fully qualified class name that implements `Io.Builder` interface. |

| [[release-3-1-0-incubating]] |
| === TinkerPop 3.1.0 (Release Date: November 16, 2015) |
| |
| This release also includes changes from <<./changelog-3.0.x.asciidoc#release-3-0-1-incubating, 3.0.1-incubating>> and <<./changelog-3.0.x.asciidoc#release-3-0-2-incubating, 3.0.2-incubating>>. |
| |
| * Fixed bug in Gryo and GraphSON (with embedded types) serialization for serialization of results returned from `Map.entrySet()`. |
| * `Transaction` settings for `onReadWrite` and `onClose` are now `ThreadLocal` in nature of standard transactions. |
| * Optimized `BulkLoaderVertexProgram`. It now uses `EventStrategy` to monitor what the underlying `BulkLoader` implementation does (e.g. whether it creates a new vertex or returns an existing). |
| * Integrated `NumberHelper` in `SumStep`, `MinStep`, `MaxStep` and `MeanStep` (local and global step variants). |
| * Gremlin Console remoting to Gremlin Server now supports a configuration option for assigning aliases. |
| * `CountMatchAlgorithm`, in OLAP, now biases traversal selection towards those traversals that start at the current traverser location to reduce message passing. |
| * Fixed a file stream bug in Hadoop OLTP that showed up if the streamed file was more than 2G of data. |
| * Added the ability to set thread local properties in `SparkGraphComputer` when using a persistent context. |
| * Bumped to Neo4j 2.3.0. |
| * Deprecated "rebindings" as an argument to Gremlin Server and replaced it with "aliases". |
| * Added `PersistedInputRDD` and `PersistedOutputRDD` which enables `SparkGraphComputer` to store the graph RDD in the context between jobs (no HDFS serialization required). |
| * Renamed the `public static String` configuration variable names of TinkerGraph (deprecated old variables). |
| * Added `GraphComputer.configure(key,value)` to allow engine-specific configurations. |
| * `GraphStep` is no longer in the `sideEffect`-package and is now in `map`-package (breaking change). |
| * Added support for mid-traversal `V()`-steps (`GraphStep` semantics updated). |
| * Fixed `Number` handling in `Operator` enums. Prior this change a lot of operations on mixed `Number` types returned a wrong result (wrong data type). |
| * Fixed a bug in Gremlin Server/Driver serializer where empty buffers were getting returned in certain cases. |
| * Renamed `ConjunctionX` to `ConnectiveX` because "conjunction" is assumed "and" (disjunction "or"), where "connective" is the parent concept. |
| * Removed `PathIdentityStep` as it was a hack that is now solved by `Traversal.Admin.addTraverserRequirement()`. |
| * Added `Traversal.Admin.addTraverserRequirement()` to allow a traversal strategy or source to add requirements (not only step determined anymore). |
| * Added `TraverserRequirement.ONE_BULK` to state the traverser does not handle bulk. |
| * Added `GraphTraversalSource.withBulk(boolean)` to enabled users to compute only using `bulk=1`. |
| * Gremlin Server supports Netty native transport on linux. |
| * Removed the need for `GFunction` (etc.) closure wrappers in Gremlin-Groovy as `as Function` can be used to convert closures accordingly. |
| * Added `SelectColumnStep` (`select(keys)` and `select(values)`). Deprecated `mapKeys()` and `mapValues()`. |
| * Renamed `gremlin.hadoop.graphInputRDD` and `gremlin.hadoop.graphOutputRDD` to `gremlin.spark.graphInputRDD` and `gremlin.spark.graphOutputRDD`, respectively. |
| * Fixed a bug in `FoldStep` around bulking. This could be a breaking change, but it is the correct semantics. |
| * Previous `group()`-behavior steps are accessible via the deprecated `groupV3d0()`-steps. |
| * `GroupStep` and `GroupSideEffectStep` now do lazy reductions to reduce memory footprint. Breaking change for `group()` semantics. |
| * Added `GroupStepHelper` with various static methods and classes that are used by both `GroupStep` and `GroupSideEffectStep`. |
| * Added `BarrierStep` interface with `processAllStarts()` method which process all starts up to yielding the barrier result. |
| * Fixed a severe threading issue in `TinkerGraphComputer`. |
| * The location of the jars in HDFS is now `hadoop-gremlin-x.y.z-libs` to ensure multiple TinkerPop versions don't clash. |
| * `GiraphGraphComputer` will only upload the jars to HDFS if it doesn't already exist (to help speed up startup time). |
| * `GiraphGraphComputer.workers()` is smart about using threads and machines to load balance TinkerPop workers across cluster. |
| * `GraphComputer.workers(int)` allows the user to programmatically set the number of workers to spawn. |
| * Added `GryoSerializer` as the new recommended Spark `Serializer`. Handles `Graph` and `GryoMapper` registries. |
| * `GryoPool` now makes use of `GryoPool.Builder` for its construction. |
| * Bumped to Apache Hadoop 2.7.1. |
| * Bumped to Apache Giraph 1.1.0. |
| * Bumped to Apache Spark 1.5.1. |
| * Split Hadoop-Gremlin apart such there is now `hadoop-gremlin`, `spark-gremlin`, and `giraph-gremlin` (and respective `GremlinPlugins`). |
| * Added `LambdaCollectingBarrierStep` which generalizes `NoOpBarrierStep` and allows for `barrier(normSack)`-type operations. |
| * Fixed bugs in the Gremlin Server's NIO protocol both on the server and driver side. |
| * Added `Path.popEquals(Pop,Object)` to check for path equality based on `Pop` (useful for `TraverserRequirement.LABELED_PATH`). |
| * Added `Operator.assign` to allow setting a direct value. |
| * `Operator` is now a `BinaryOperator<Object>` with appropriate typecasting for respective number operators. |
| * Simplified `SackValueStep` so it now supports both `sack(function)` and `sack(function).by()`. Deprecated `sack(function,string)` . |
| * Added `Parameters` object to allow for the parameters of a step to be retrieved at runtime via a traversal. |
| * Redesigned (though backwards compatible) `AddEdgeStep`, `AddVertexStep`, and `AddPropertyStep` (and respective `GraphTraversal` API). |
| * Added `GraphTraversalSource.inject()` so users can spawn a traverser with non-graph objects. |
| * `GraphStep` can now take a single argument `Collection` which is either elements or element ids (i.e. `g.V([1,2,3])` is supported now). |
| * Added `LoopsStep` to make the loop counter accessible within `repeat()`, `until()` and `emit()`. |
| * Gephi Plugin no longer requires manual insert of `store` steps to visualize a traversal. |
| * Added a `TinkerIoRegistry` that registers a custom serializer for Gryo that will serialize an entire `TinkerGraph` instance. |
| * Added configuration options to Gephi Plugin for setting the size of nodes visualized. |
| * Replaced `DedupBijectionStrategy` with the more effective `FilterRankingStrategy`. |
| * `ComputerAwareSteps` must not only handle step ids, but also step labels. |
| * Renamed `B_O_P_SE_SL_Traverser` to `B_LP_O_P_SE_SL_Traverser` as it now supports `TraverserRequirement.LABELED_PATH`. |
| * Added `B_LP_O_S_SE_SL_Traverser` in support of `TraverserRequirement.LABELED_PATH`. |
| * Added `TraverserRequirement.LABELED_PATH` which only generates path data for steps that are labeled (greatly increases the likelihood of bulking). |
| * Fixed a bug in `Path` usage that required an API update: `Path.addLabel()` is now `Path.extend(Set<String>)` and `Traverser.addLabels(Set<String>)`. |
| * Made `Path` iterable, so that it can be ``unfold()``'ed and used by local steps like `min(local)`, `max(local)`, etc. |
| * `WhereTraversalStep` and `WherePredicateStep` are now the only "special" `Scoping` steps after `MatchStartStep` in `match()`. |
