Nightly is no longer being built.

Dgraph development (pre-release) build which is updated every night.
You can automatically install the nightly binaries along with the assets by running
`curl https://get.dgraph.io -sSf | bash -s nightly`.

v1.0.5

Features

• Option to have server side sequencing.
• Ability to specify whitelisted IP addresses for admin actions.

Bugfixes

• Fix bug where predicate with string type sometimes appeared as _:uidffffffffffffffff in exports.
• Validate facet value should be according to the facet type supplied when mutating using NQuads (#2074).
• Use time.Equal function for comparing predicates with datetime(#2219).
• Skip BitEmptyPosting for has queries.
• Return error from query if we don't serve the group for the attribute instead of crashing (#2227).
• Send maxpending in connection state to server (#2236).
• Fix bug in SP* transactions (#2148).
• Batch and send during snapshot to make snapshots faster.
• Don't skip schema keys while calculating tablets served.
• Fix the issue which could lead to snapshot getting blocked for a cluster with replicas (#2266).
• Dgraph server retries indefinitely to connect to Zero.
• Allow filtering and regex queries for list types with lossy tokenizers.
• Dgraph server segfault in worker package (#2322).
• Node crashes can lead to the loss of inserted triples (#2290).

Improvements

• Cancel pending transactions for a predicate when predicate move is initiated.
• Move Go client to its own repo at dgraph-io/dgo.
• Make expand(_all_) return value and uid facets.

Note the following changes if you are upgrading from an older version:

• Add an option to specify a @lang directive in schema for predicates with lang tags.
• Flag memory_mb has been changed to lru_mb. The default recommended value for lru_mb is
  one-third of the total RAM available on the server.

v1.0.4

Features

• Support for empty strings in query attributes.
• Support GraphQL vars in first, offset and after at root.
• Add support for query_edge_limit flag which can be used to limit the number of results for shortest path, recurse queries.
• Make rebalance interval a flag for Zero.
• Return latency information for mutation operations.
• Support @upsert directive in the schema. This replaces the IgnoreIndexConflict flag which was part of the mutation object earlier. The IgnoreIndexConflict flag would no longer be parsed by the server.

Bugfixes

• Fix issues with predicate deletion in a cluster.
• Handle errors from posting.Get.
• Correctly update commitTs while committing and startTs == deleteTs.

• Run cleanPredicate and proposeKeyValues sequentially.
• Serialize connect requests in Zero.

Improvements

• Retry snapshot retrieval and join cluster indefinitely.
• Make client directory optional in dgraph live.
• Do snapshot in Zero in a goroutine so that Run loop isn't blocked.

v1.0.3

Features

• Support for specifying blank nodes as part of JSON mutation.
• dgraph version command to check current version.
• Added moveTablet endpoint to Zero to allow initiating a predicate move.

Changes

• --zero_addr flag changed to --zero for dgraph bulk command.
• Default ports for Zero have been changed 7080 => 5080(grpc) and 8080 => 6080(http).
• Default port for Ratel has been changed 8081 => 8000 so that it doesn't conflict with Dgraph server ports.
• Print predicate name as part of the warning about long terms for exact index.

Bugfixes

• Out of range error while doing eq query.
• Reduce maxBackOffDelay to 10 sec so that leader election is faster after a restart (#2031).
• Fix bugs with predicate move where some data was not sent and schema not loaded properly on
  replicas (#2047).
• Fix the total number of RDF's processed when live loader ends (#2052).
• Reindex data when schema is changed to list type to fix adding and deleting new data (#2060).
• Correctly update uidMatrix when facetOrder is supplied (#2083).
• Inequality operator(gt and lt) result for non-lossy tokenizers (#2085).
• Change how purging is done to fix CPU spiking when Dgraph is idle (#2038).

Thanks to @sboorlagadda and @kshitij10496 for their contributions.

v1.0.2

Improvements

• Remove StartTs field from api.Operation.
• Print error message in live loader if it's not ErrAborted. Also, stop using membership state and
  instead use the address given by the user.
• Only send keys corresponding to data that was mutated.

Bugfixes

• Always return predicates of list type in an array.
• Edges without facet values are also returned when performing sort on facet.
• Don't derive schema while deleting edges.
• Better error checking when accessing posting lists. Fixes bug where parts of queries are sometimes omitted when system is under heavy load.
• Fix missing error check in mutation handling when using CommitNow (gave incorrect error).
• Fix bug where eq didn't work correctly for the fulltext index.
• Fix race because of which replicas flag was not respected.
• Fix bug with key copy during predicate move.
• Fix race in merging keys from btree and badger iterator.
• Fix snapshot retrieval for new nodes by retrieving it before joining the cluster.
• Write schema at timestamp 1 in bulk loader.
• Fix unexpected meta fatal error.
• Fix groupby result in case the child being grouped open has multiple parents.

v1.0.1

Bugfixes

• Wait for background goroutines to finish in posting package on shutdown. (#1939)
• Return error if we cant parse the uid given in JSON input for mutations. (#1937)
• Don't remove _predicate_ schema from disk during drop all. (#1925)
• Fix results not being returned on restart. (#1935)

• Prohibit string to password schema change.
• Make purging less aggressive.
• Check if GraphQL Variable is defined before using.

Bugfixes

• Language tag parsing in queries now accepts digits (in line with RDF parsing).
• Ensure that GraphQL variables are declared before use.
• Membership stream doesn't get stuck if node steps down as leader.
• Fix issue where sets were not being returned after doing a S P * deletion when part of same
  transaction.
• Empty string values are stored as it is and no strings have special meaning now.
• Correctly update order of facetMatrix when orderdesc/orderasc is applied.
• Allow live and bulk loaders to work with multiple zeros.
• Fix sorting for predicates with multiple language tags.
• Fix alias edge cases in normalize directive.
• Allow reading new index key mutated as part of same transaction.
• Fix bug in value log GC in badger.
• SIGINT now forces a shutdown after 5 seconds when there are pending RPCs.

v0.9.4

This release contains a small fix which allows using the data directories from previous versions(v0.9.0-v0.9.2).
Users should skip v0.9.3 and upgrade to v0.9.4 instead.

Improvement

• Max size for GRPC messages that can be sent by the server is now set to 4GB.

v0.9.3

This release contains important bugfixes and improvements.

Features

• Support for alias while asking for facets.
• Support for general configuration via environment variables and configuration files.
• IgnoreIndexConflict field in api.Mutation which allows ignoring conflicts on index keys.

Improvements

• expand(_all_) now correctly gives all language variants of a string.
• When showing a predicate with list type, only values without a language tag are shown. To get the values of the predicate that are tagged with a language, query the predicate with that language explicitly.
• expand(_all_) now follows reverse edges.
• Don't return uid for nodes without any children when requested through debug flag.
• GraphQL variables for HTTP endpoints. Variable map can be set as a JSON
  object using the X-Dgraph-Vars header.
• Live loader treats subjects/predicates that look like UIDs as existing nodes
  rather than new nodes.
• Proto definitions are split into intern and api. Users using v0.9.x of the Go client will have to change their code to use api instead of proto as package name.

Bugfixes

• Indexes now correctly maintained when deleting via S * * and S P *.
• Validate the address advertised by dgraph nodes.
• Store/Restore peer map on snapshot.
• Fix rdfs per second reporting in live loader.
• Fix bug in @groupby queries where predicate was converted to lower case.
• Fix bug in lru eviction.

Dgraph v0.9.2 Release

This release contains bugfixes, features and minor improvements.

Features

• Support for removing dead nodes from the quorum.
• Support for alias in groupby queries.
• DeleteEdges helper function for Go client.

Improvements

• Dgraph tries to abort long running/abandoned transactions.
• Reduce dependencies for the Go client.
• depth and loop arguments are now passed inside @recurse.

Bugfixes

• base36 encode keys which are part of the TxnContext before sending to the client. This makes sure they are valid UTF-8 strings and the client can parse them.
• Fix --ui flag parsing.
• Fix TLS flag parsing for Dgraph server and live loader.
• Fix race condition in expand(_all_) queries. #1783
