Nearly a year after launching GX Core 1.0, we're ending support for version 0.18 and earlier in GX Cloud. Versions of GX Core below 1.0 will sunset on October 1, 2025. While this means some changes for teams still using these versions, it finalizes the transition to the significantly improved data validation experience we introduced in August 2024.
What is changing
If you're using version 0.18 or earlier, you'll no longer be able to run validations or Expectation Suites. Three deprecated features are also being removed:
Custom Expectations (older implementation)
Value-Based Batches
What you get instead
The move to supported GX Core versions brings you all the improvements we've been refining since the 1.0 release:
Clearer code structure. APIs now follow intuitive patterns like context.<resource>.<method>, making functions easier to find and use consistently across your projects.
Built-in guidance. Typed parameters tell you exactly what arguments each function needs, with IDE integration that includes auto-fill and parameter hints as you work. No more guessing or constant documentation searches.
No more YAML wrestling. Configuration APIs work directly with code instead of requiring YAML string formatting, eliminating a common source of syntax errors and setup frustrations.
Better debugging experience. Error messages are more specific and actionable, while Expectation testing provides clearer feedback about what went wrong and where.
Fewer unexpected issues. The comprehensive code overhaul in GX Core resolved many bugs that affected reliability in earlier versions.
Ready-to-use components. Choose from a range of fully-configured Expectations designed to address various data quality issues, or create custom ones using the streamlined workflow.
Making the Move
Not sure which version you're running? Check our migration guide for version identification and upgrade steps. Our community Slack is also available for questions during the transition.
This change completes the transformation we began with GX Core 1.0—building tools that work predictably and help data teams focus on their actual work rather than fighting with their validation framework.
With the October 1st deadline approaching, now's the perfect time to migrate. Check out what’s new in GX Cloud.
