v1.9.5 - Deprecation Warnings for Legacy Configuration Models (2025-12-29)#

What Changed?#

This release adds deprecation warnings to DaqConfig and ScanConfig configuration models, guiding users toward the unified SamplerConfig format. Users will see warnings when using the old configuration sections, with clear migration instructions provided. All existing configurations continue to work without changes—this is a preparation step for v1.11.0 where the old models will be removed.


What’s New#

Deprecation Warnings for Configuration Models#

What it does: When you load a configuration file using the old [daq] or [scan] sections, you’ll now receive a DeprecationWarning. This warning tells you exactly what to do:

  • Migrate from [daq] to [sampler] with mode = "count_based"

  • Migrate from [scan] to [sampler] with mode = "time_based"

The warning includes a link to the migration guide with detailed instructions and examples.

How to use it: No action needed unless you want to avoid warnings. When you see the warning:

  1. Read the migration guide: docs/users/migration.md

  2. Update your TOML configuration file

  3. Re-run your command—the warning should disappear

Example warning:

DeprecationWarning: DaqConfig is deprecated since v1.5.0 and will be removed in v1.11.0.
Please migrate to SamplerConfig with mode='count_based'.
See migration guide: https://docs.example.com/migration/
