+# What's new in Apache Atlas 1.0?
+
+## Features
+
+* Introduction of relationships as a first-class type
+* Support for propagation of classifications along entity relationships – like lineage
+* Fine-grained metadata security, which enables access controls up to entity instance level
+* Introduction of Glossary feature
+* Introduction of V2 style notifications
+* Introduction of Atlas hook for HBase
+* Support for Cassandra and Elasticsearch (tech-preview)
+    
+## Updates
+
+* Graph store has been updated from Titan 0.5.4 to JanusGraph 0.2.0
+* DSL rewrite, to replace use of Scala based implementation with ANTLR
+* Performance improvements in Atlas Hooks, by switching to use V2 style notifications
+* Significant updates in Atlas Web UI
+
+## Changes
+
+### DSL search
+
+With DSL rewrite and simplification, some older constructs may not work. Here's a list of behavior changes from previous
+releases. More DSL related changes can be found [here](Search-Advanced.html).
+
+   * When filtering or narrowing results using string attribute, the value **MUST** be enclosed in double quotes
+      * Table name="Table1"
+      * Table where name="Table1"
+   * Join queries are no longer supported e.g. hive_table, hive_db 
+   * Select clauses only work with immediate entity attributes or a single referred (entity) type.
+      * Table select name, owner
+      * Table select Columns 
+      * Table select name, owner, Columns _*(won't work)*_
+   * OrderBy clause can only be used with a _*single primitive*_ attribute.
+   * GroupBy clause can only be used with a _*single primitive*_ attribute.
+      * Table groupby name
+      * Table groupby Columns (won't work)
+   * Typename can't have multiple aliases
+      * Table as t (OK)
+      * Table as t1, t2 (won't work)
+  * Has clause only works with primitive attributes.
+     * Table has name
+      * Table has Columns or Table has DB (NOT supported)
+  * Aggregator clause can only be used with a _*single primitive*_ attribute.
+      * Table select min(name)
+      * Table select max(name)
+      * Table select sum(createTime)
+      * Table select min(Columns) (won't work)
+      * Table select max(Columns) (won't work)
+      * Table select sum(Columns) (won't work)
+  * Aggregator clause can't be repeated with different _*primitive attribute*_, the clause appearing last would take preference.
+      * Table select min(name), min(createTime) will ignore _*min(name)*_
+  * Limit and offset are not applicable when using aggregator clauses (min, max, sum)
+      *  Table select min(name) limit 10 offset 5 - min(name) is computed over **ALL** entities of type Asset
