Release Notes 4.5.0¶

Improvements¶

Compose Performance: We are consistently working to improve Compose performance. In this release, we made a lot of behind the scenes improvements in order to enhance your experience and efficiency when using Compose.
Catalog Column Page: Catalog Column pages now have the same updated layout as Table Catalog pages.
Rich Metadata Displayed in Catalog: We now display new metadata for Table and Column Catalog pages. We display source comments imported from the database, keys & indices details. As well as exposing Table descriptions, table synonyms, and the “last altered” timestamp.
We’ve added support for a new authentication method on SQL Server

Hive & Tez: Alation can now accept query logs from the Tez execution engine to compute usage stats, identify top users, and more.
Tableau: Tableau workbooks endorsed in Alation are marked “certified” in Tableau Server

Alation now shows schemas in the catalog even if they have no tables for the following data source types: PostgreSQL, Teradata, Vertica, MySQL, SAP Hana, Snowflake
When a Tableau instance is removed from the Alation catalog, its reports are now removed from the Catalog sidebar
the Alation automatic update system no longer sends emails to the server’s system administrators

If you are using LDAP Authentication, you can set up user groups in Alation using your existing LDAP groups.
As an admin, you can now manage the krb5.conf file in Alation through the UI
We’ve added Tags to Alation DB. This must be enabled via the command line.
