[Copilot]

This PR adds a detailed documentation of all major features and enhancements that were merged to the main branch of the Antenna repository during 2025.

What's Added

The new 2025_FEATURES_SUMMARY.md document provides a comprehensive overview of 10 major feature additions based on analysis of Django migrations, model changes, and code structure:

Key Features Documented

1. Tagging System for Taxa (May 2025) - Project-scoped flexible labeling system for taxonomic classification
2. Project Feature Flags System (July-September 2025) - Configurable feature toggles using Pydantic schemas
3. Project Draft Mode (September 2025) - Work-in-progress status for projects under development
4. Enhanced Default Filters (August 2025) - Sophisticated filtering with include/exclude taxa lists and score thresholds
5. Data Export System (April 2025) - Complete new Django app supporting multiple export formats (JSON, CSV)
6. Taxon Visual Enhancements (September 2025) - Cover images, credits, and field guide integration
7. ML Pipeline Configuration (March 2025) - Per-project pipeline settings with ProjectPipelineConfig model
8. Algorithm Management (February 2025) - Unique constraints on algorithm name/version pairs
9. Taxonomic Classification Support (January-February 2025) - Common names and expanded taxonomic ranks
10. Enhanced Project Permissions - Granular permission controls for deployments, collections, storage, and jobs

Documentation Value

This summary serves as:

• Historical Record: Tracks the evolution of the platform throughout 2025
• Feature Reference: Helps developers understand available functionality
• Migration Guide: Documents database schema changes and their purposes
• Product Overview: Shows the platform's growth in user experience, data management, ML operations, and system flexibility

Copilot was not able to access the actual git commits or closed PRs to generate this list, but it did a decent job by looking at the dated-modified timestamps of files in the repo and summarizing the code.

I used this list while creating the slides for our presentation in Aarhus. Here is a longer list of features we added, but still not comprehensive.

• Integration of a Global Moth Species Classifier
• Management system for algorithms and ML pipelines
• Filtering support for Occurrences
• Improved identification workflow for experts
• User permissions & roles
• Project feature flag system
• Private draft mode for projects
• Data export system
• Visual enhancements for taxa
• Experimental support for feature vectors and image clustering
• Taxon reference images
• Tagging system for taxa
• Taxa lists
• Improved species predictions with post-processing methods such as tracking, rank downgrades and size filters.
