C2026.9.0
XIRR was not supported on Amazon Redshift
XIRR is a Public Preview feature.
AtScale's XIRR UDF became inoperable after June 30, 2026 due to an AWS Redshift deprecation of Python language support for UDFs. AtScale has migrated to a Lambda UDF for C2026.9. If you require this XIRR Lambda UDF for an earlier version, reach out to AtScale Support.
For updated instructions on creating the XIRR Lambda UDF, see XIRR.
ATSCALE-50971
Tableau: Relative date filters on weeks failed
In Tableau, creating a relative date filter with a time unit of weeks failed with an error. This was because AtScale generated the outbound query with the wrong syntax for the data warehouse. This issue has been resolved.
ATSCALE-49201

The Workspace panel sometimes displayed duplicate entries for newly created objects. This issue has been resolved.
ATSCALE-52198
Query result cache was disabled for all OIDC-federated users
The query result cache was disabled for all OIDC-federated users. This issue has been resolved.
ATSCALE-52507
Data warehouse connection validation failed on Google BigQuery
AtScale's data warehouse connection validation failed on Google BigQuery when BigQuery had an organization policy that restricted query jobs based on region. AtScale's connection validation query automatically ran in the US, so if BigQuery's organization policy excluded the US region, the job failed. This issue has been resolved.
ATSCALE-52036
Aggregate builds sometimes got stuck in the Building state
Aggregate builds sometimes got stuck in the Building state for extended periods, with no active queries appearing in either AtScale or the data warehouse. This issue has been resolved.
ATSCALE-51796

Looker connections failed when AtScale was configured with an egress proxy. This issue has been resolved.
ATSCALE-51322
Some MCP Server tools failed on Snowflake Cortex

ATSCALE-51219
Queries failed with an "Aggregate functions cannot be nested" error
Some user queries failed with an error of Aggregate functions cannot be nested, regardless of whether or not the queries actually hit aggregates. This issue has been resolved.
ATSCALE-50935
Sharable statistics queries failed in Google BigQuery with errors on DATETIME and STRING columns
Sharable statistics queries failed in Google BigQuery with UNIX_SECONDS casting errors on DATETIME and STRING columns. This was because AtScale did not properly convert these data types to TIMESTAMP, as required by UNIX_SECONDS. This issue has been resolved.
ATSCALE-50843
AtScale created duplicate aggregates for some semi-additive metrics
AtScale created duplicate aggregates for semi-additive metrics whose sort keys were based on the same physical columns as their value keys. This issue has been resolved.
ATSCALE-50288
Invalid deployed models prevented BI tools that used the PostgreSQL driver from connecting to valid models
If a deployed model became invalid because its underlying physical tables were removed or renamed outside of AtScale, BI tools that use the PostgreSQL driver (such as Tableau) were prevented from connecting to any deployed model, even valid ones. This issue has been resolved.
ATSCALE-49815
Design Center highlighted selected dataset columns in black
Design Center highlighted selected dataset columns in black, which was difficult to see. This issue has been resolved: Selected columns are now highlighted in blue.
ATSCALE-41022
Redis resourcesPreset defaulted to "nano"
When global.resourcesPreset is set to none, no CPU or memory resource limits are placed on the AtScale components. The atscale-redis component was inadvertently using nano as its default resourcesPreset value, causing OOM errors in the container at runtime and making it unusable. This issue has been resolved: The default value for atscale-redis is now none, so the global.resourcesPreset rule is respected.
