You can use Bitbucket to manage versions of your notebooks. Learn more.

PRES-3113: Improved accounting of queued work for calculation of optimal size in autoscaling. PRES-3131: Qubole has added http-server.log.max-size=1GB in config.properties to ensure that the HTTP request log is rolled over regularly if the file size reaches 1GB. PRES-3163: It fixes a bug which could cause some additional nodes to be added to the cluster for a short duration during spot loss. PRES-3187: It fixes a bug that caused the Download as CSV file option on Analyze UI to incorrectly download the file as Tab separated.
13th Nov, 2019 (08:47 AM PST)	57.0.64	Enhancement	ACM-5958: Qubole has done improvements in cluster UI page’s loading to resolve the slow-loading cluster UI page.

AN-1708: Permalinks for Hive tables on the new Analyze page now contain account IDs. When you navigate to a Hive table from a different account, a confirmation dialog box appears. QUEST-321: Users can now use custom code in Python language for creating a streaming pipeline. QUEST-332: Users can select AVRO as one of the input formats when creating a streaming pipeline in assisted mode with Kafka as source. QUEST-341: Users can add additional configurations such as user defined metadata for data written to S3 sink. SPAR-3514: The Test Run option in the QuEST UI, processes a limited number of records and maintains separate temporary checkpoint location to prevent any corruption to the runtime production checkpoint. SPAR-3591: Users can pass x-amz-meta-metadata(key1=value1,key2=val2) while creating a new streaming job with s3 as the sink by setting the option fs.s3a.user.metadata as key1=val1,key2=val2. The streaming application creates new files with this metadata. This is supported on Spark 2.3.2 and later versions. TOOLS-1440: The `s3cmd` version is upgraded from 1.5.2 to 2.0.2.
		Bug fix	AN-1974: Column headers now appear on the Analyze page for large Hive queries (approximately 65KB and more).

PRES-2254: In a Presto notebook, you can now set zeppelin.presto.stacktrace as an interpreter property for displaying stacktrace for certain errors. PRES-2600: These are the new enhancements in the Presto notebooks: You can now set session properties in Presto notebooks in a paragraph and run it. When set, these session properties are applicable to paragraphs in the notebook’s current session. In Presto notebooks, for improving debugging experience, the source field is set as notebook_<notebook-name>_<notebook-id> and in the dashboards, the source field is set as dashboard_<dashboard-name>_<dashboard-id>_<source-note-id>. A source field is directly searchable in the Presto UI. For example, in the Presto UI, you can search a notebook by its name or ID to quickly filter queries, which are run from that specific notebook while debugging an error.
		Bug fix	PRES-2727: This fixes the issue where queries with a table containing sub column names of a struct column type starting with numbers failed. Sub-column names of a struct column type can now start with numbers.
