Date and time of release	Version	Change type	Change
16th Apr, 2021 (11:59 CST)	59.5	Bug fix	JUPY-630 Fixed the error in the branch details of the gitlab server, configuring the bastion with the account public SSH key.
29th Sep, 2020 (10:22 AM PST)	59.0.1045	Enhancement	PRES-3435: The QueryTracker link is now available in the Workbench/Analyze UI’s Logs tab for queries run through the third-generation drivers. PRES-3722: Optimization is added to push null filters to table scans by inferring them from the JOIN criteria of equi-joins and semi-joins in Presto version 317 and later. You can enable it through optimize-nulls-in-joins as a Presto cluster override or optimize_nulls_in_join as a session property. Use this enhancement to reduce the cost of performing JOIN operations when JOIN columns contain a significant number of NULLs. PRES-3724: Backported hive.ignore-corrupted-statistics into Presto version 0.208 to avoid query failures in case of corrupted Hive metastore statistics and it is enabled by default. Presto version 317 supported this property, which is now enabled by default. PRES-3748: Presto query retries for memory exceeded exceptions are triggered in a graded manner. Qubole retries the failed query in three steps. First two steps occur on the cluster size that lies between the minimum and the maximum cluster size. The last step of occurs at the maximum cluster size. To know more, see Graded Presto Query Retries. This enhancement is part of Gradual Rollout. PRES-3761: The Presto Mongo Connector now supports querying Cosmos DB using Mongo APIs. PRES-3788: You can now add a comma-separated list of endpoints and pass them as cluster override values of qubole.bypass-authentication-endpoints if you want to skip authentication of such endpoints. For example, if qubole.bypass-authentication-endpoints= /,query,node, then only endpoints that matches with these are skipped for authentication. Contact Qubole Support to enable this enhancement at the account level.
		Bug fix	PRES-3632: Fixed the File '000000' does not match the standard naming pattern error that Presto threw when trying to read bucketed Hive tables. Qubole Hive INSERT commands had written bucketed Hive tables. PRES-3787: Fixed the Ranger access control for Presto views in Presto version 0.208. PRES-3790: Fixed the issue that failed queries when there was no space before or after a single line comment in Presto queries. RUB-239: Fixed the issue in RubiX that sometimes caused query failures around the cache data invalidation. PRES-3660: Fixed the Presto query failure with Error opening Hive split : <FILENAME>: null when Rubix was enabled. PRES-3701: Fixed the connection leak in RetryingPooledThriftClient of RubiX, which caused the slowness in source stages that slowed down the query. PRES-3708: Fixed the possible deadlock between Hive loadPartitionByName and getTable when the Hive metastore caching is enabled with refresh TTL (time-to-live). PRES-3543: Fixed the issue where the aggregation node in case of a UNION query (when union sources are tablescan node and values node) did not use the distributed partitioning and caused an OOM exception. It is fixed by disregarding the SINGLE distribution for the UNION query. PRES-3588: Fixed issues related to updating the table statistics performance. As a result, the bug fix has improved the performance of updating table statistics. In addition, a new configuration property, hive.table-statistics-enabled with its default value set to true is added that you can use to disable updating table statistics. PRES-3602: Fixed the issue in reading the TEXT file collection delimiter configured in the Hive versions (earlier to Hive 3.0) in Presto version 317. PRES-3604: Fixed the Ranger access control for Presto views that had earlier failed. PRES-3618: The Presto catalog configuration for external data sources that skipped validation in Qubole was not added to the cluster earlier. Fixed this issue and now such configuration is added to the cluster. PRES-3641: Fixed the failure in planning for spatial JOINs with dynamic filtering enabled. PRES-3662: Fixed the issue where pushing configuration to a cluster corrupted the Presto configuration and failed the Presto server restart. PRES-3672: Fixed query failures that occurred as too many partitions’ metadata were requested from the metastore in Presto versions 0.208 and 317. PRES-3673: Fixed the issue where the Presto cluster start failed when resource-groups.user-scaling-limits-enable was turned on and resource groups were configured by a user. PRES-3677: Fixed the issue where the default location (DefLoc) was picked as the DB location of non-default schemas in the Presto version 317. The correct behavior is that DefLoc should be the DB location of only the default schema.
24th Aug, 2020 (09:22 AM PST)	59.0.1040	Bug fix	JUPY-929: Dependencies that were installed through the Environments page were not accessible for the scheduled and API runs of Python notebooks. This issue is fixed.
21st Aug, 2020 (11:31 AM PST)	59.0.1037	Bug fix	ZEP-4789: The paragraph status was not getting updated after the web socket reconnect. This issue is fixed. ZEP-4590: Interpreter settings were getting lost because of _COPYING_ file present in defloc. This issue is fixed. ZEP-4130: Notebook commands were failing when the status was NOT_STARTED_RUNNING_NOTEBOOK. To fix this issue, 20 retries at an interval of 10 seconds upto 3 min is added when the notebook command status fetched is NOT_STARTED_RUNNING_NOTEBOOK. ZEP-4642: Notebook rendering was delayed due to extra web socket calls made for each paragraph to fetch editor settings. This issue is fixed.
2nd Jun, 2020 (11:09 AM PST)	59.0.1015	Bug fix	PRES-3543: Fixed the issue where the aggregation node in case of a UNION query (when union sources are tablescan node and values node) did not use the distributed partitioning and caused an OOM exception.

PRES-3677: Fixed the issue where the default location (DefLoc) was picked as the DB location of non-default schemas in the Presto version 317. The correct behavior is that DefLoc should be the DB location of only the default schema. PRES-3694: Fixed an issue to allow overriding of the -Xmx configuration value to less than 80% in the cluster’s Presto overrides. PRES-3708: Fixed the possible deadlock between Hive loadPartitionByName and getTable when the Hive metastore caching is enabled with refresh TTL (time-to-live).
