+# Changelog
+
+The release log for Ax.
+
+## [1.1.0] -- Aug 11, 2025
+#### New Features
+* New option for the `method` parameter in `client.configure_generation_strategy`:
+    `quality` -- allows uers to indicate they would like Ax to generate the highest
+    quality candidates it is able to at the expense of slower runtime (#4042)
+* New logic for deciding which analyses to produce by default in
+    `client.compute_analyses` (#4013)
+* New parameters in `client.summarize` allow users to filter their summary by trial
+    index and/or trial status (#4012, #4118)
+
+#### Bug Fixes
+* Allow `client.summarize` to be called without a `GenerationStrategy` being set
+    (i.e. before `client.configure_generation_strategy` or `client.get_next_trails`
+    has been called.) (#3801)
+* Fixed incorrect grouping in `TopSurfacesAnalysis` (#4095)
+* Fixed `ContourPlot` failing to compute in certain search spaces with parameter
+    constraints (#4124)
+* Misc. plotting fixes and improvements
+
+#### Other changes
+* Bumped pinned [botorch](https://github.com/pytorch/botorch) version to 0.15.0
+* Performance improvements in `SensitivityAnalysis` (#3891)
+* Improved optimization performance in constrained optimization settings (#3585)
+* Augmented logging in `Client`, early stopping module (#4044, #4108)
