Custom masking support for Data Masking

Docs

You can now configure advanced masking options when using erase method in the Data Masking utility. This feature provides granular control to protect sensitive information while maintaining data readability and structure.

The new options to use with erase :

  • Dynamic Mask: Preserves text length and structure by replacing characters with *
  • Custom Mask: Apply simple pattern like "XX-XX"
  • Regex Mask: Advanced pattern-based masking for complex data formats
  • Field-specific Allows different masking rules for different data fields

Disable flushing metrics using environment variables

Docs

You can now set the POWERTOOLS_METRICS_DISABLES environment variable to control the metrics output. This is useful when you want to silent metrics in a non-production environment. When POWERTOOLS_DEV is enabled, the metrics are also suppressed, but you can always override it by setting POWERTOOLS_METRICS_DISABLED=false when you want to continue emitting metrics while in dev mode.

Clearing all appended keys with clear_state() method

Docs

We have added a new clear_state() to Logger to easily remove any temporary keys you have added. This is useful when you add multiple custom keys conditionally or when you emit canonical or wide logs.
