v5.0.0-beta1 ​

Changelog ​

Major SDK Update ​

This release introduces a newly rebuilt SDK foundation designed to improve long-term stability, maintainability, and performance.

Improvements ​

  • Reworked the internal SDK architecture for better reliability and future extensibility.
  • Improved runtime stability across supported environments.
  • Optimized core processing flow for more consistent behavior.
  • Enhanced error handling and recovery logic.
  • Refined internal resource management to reduce unnecessary overhead.
  • Improved compatibility with recent platform and dependency updates.
  • Cleaned up legacy implementation details to simplify future development.

Notes ​

This update does not require changes to the existing public integration flow unless otherwise specified in the integration guide.

Some internal implementation details have changed significantly, but public-facing behavior and API compatibility have been preserved where applicable.

v4.3.7 ​

Changelog ​

Stability Update ​

This release improves recognition lifecycle handling and makes repeated start and stop requests safer for production applications.

Improvements ​

  • Improved handling for duplicate recognition start and stop requests.
  • Added sample app controls for updating the recognition database more easily.
  • Improved sample app lifecycle behavior for more reliable integration testing.
  • Refined SDK state handling to reduce the chance of inconsistent runtime behavior.

v4.3.6 ​

Changelog ​

Reliability Update ​

This release strengthens SDK initialization and database update behavior for more consistent application startup and update flows.

Improvements ​

  • Improved singleton initialization for more predictable SDK setup.
  • Enhanced database version persistence during update flows.
  • Added recovery behavior for cases where pending audio pack application cannot be completed immediately.
  • Updated Android platform compatibility targets for recent development environments.

v4.3.5 ​

Changelog ​

Maintenance Update ​

This release improves state reset behavior to prevent stale recognition data from affecting later sessions.

Improvements ​

  • Refined reset handling so duplicate-detection state is cleared when SDK state is reset.
  • Improved consistency when applications restart recognition after clearing state.
  • Reduced the chance of stale runtime data affecting subsequent recognition sessions.

v4.3.4 ​

Changelog ​

Performance and Stability Update ​

This release improves event delivery behavior and campaign result consistency under active recognition workloads.

Improvements ​

  • Improved event handling under high activity to support smoother result delivery.
  • Refined campaign deduplication for more consistent recognition outcomes.
  • Reduced the chance of redundant campaign notifications in edge cases.

v4.3.3 ​

Changelog ​

Reliability and Performance Update ​

This release focuses on foreground service reliability, event delivery performance, and Android platform compatibility.

Improvements ​

  • Improved recognition result delivery performance.
  • Enhanced foreground service recovery across app restarts and reconnections.
  • Improved notification persistence for long-running recognition sessions.
  • Added explicit foreground service type support for recent Android versions.
  • Strengthened thread-safety and resource management across core SDK components.
  • Reduced duplicate campaign events across multiple delivery paths.
  • Refined internal organization to improve maintainability.

v4.3.2 ​

Changelog ​

Network Reliability Update ​

This release adds stronger network resilience for recognition requests and background delivery.

Improvements ​

  • Added configurable network handling and listener support.
  • Improved request queuing when network connectivity is unavailable.
  • Enhanced error handling for authentication and audio pack download flows.
  • Improved delayed sending behavior for queued requests.
  • Improved network monitoring compatibility across Android API levels.
  • Added Android 15 compatibility improvements for native libraries.
  • Improved metadata delivery in API requests.
  • Strengthened foreground service notification behavior.

Notes ​

Review the network handling guide if your application needs custom behavior when connectivity is unavailable.

v4.3.0 ​

Changelog ​

Background Update Support ​

This release adds support for updating recognition data independently from active recognition flows.

Improvements ​

  • Added a standalone database update method for refreshing recognition materials.
  • Added WorkManager integration guidance for periodic background updates.
  • Improved Android 15 foreground service time-limit handling.
  • Improved update behavior when recognition is not currently running.
  • Refined preference serialization and error handling.
  • Improved Android build and documentation artifact generation.

Notes ​

Applications that need automated recognition data refreshes can use the background database update guide.
