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.
