 ## Breaking changes
 
-The option `apiAllowedIPs` is now a required configuration attribute in
+### Configuration changes
-`config.json`. This option restricts access to the admin API.
 
-To retain the previous behavior that the API is per default accessible from
+- **JSON attribute naming**: All JSON configuration attributes now use `kebab-case`
-everywhere set:
+  style consistently (e.g., `api-allowed-ips` instead of `apiAllowedIPs`).
+  Update your `config.json` accordingly.
+- **Removed `disable-archive` option**: This obsolete configuration option has been removed.
+- **Removed `clusters` config section**: The separate clusters configuration section
+  has been removed. Cluster information is now derived from the job archive.
+- **`apiAllowedIPs` is now optional**: If not specified, defaults to secure settings.
+
+### Architecture changes
+
+- **MetricStore moved**: The `metricstore` package has been moved from `internal/`
+  to `pkg/` as it is now part of the public API.
+- **MySQL/MariaDB support removed**: Only SQLite is now supported as the database backend.
+- **Archive to Cleanup renaming**: Archive-related functions have been refactored
+  and renamed to "Cleanup" for clarity.
+
+### Dependency changes
+
+- **cc-lib v2**: Switched to cc-lib version 2 with updated APIs
+- **cclib NATS client**: Now using the cclib NATS client implementation

+
+## Major new features
+
+### NATS API Integration
+
+- **Real-time job events**: Subscribe to job start/stop events via NATS
+- **Node state updates**: Receive real-time node state changes via NATS
+- **Configurable subjects**: NATS API subjects are now configurable via `api-subjects`
+- **Deadlock fixes**: Improved NATS client stability and graceful shutdown
+
+### Public Dashboard
+
+- **Public-facing interface**: New public dashboard route for external users
+- **DoubleMetricPlot component**: New visualization component for comparing metrics
+- **Improved layout**: Reviewed and optimized dashboard layouts for better readability
+
+### Enhanced Node Management
+
+- **Node state tracking**: New node table in database with timestamp tracking
+- **Node state filtering**: Filter jobs by node state in systems view
+- **Node metrics improvements**: Better handling of node-level metrics and data
+- **Node list enhancements**: Improved paging, filtering, and continuous scroll support
+
+### MetricStore Improvements
+
+- **Memory tracking worker**: New worker for CCMS memory usage tracking
+- **Dynamic retention**: Support for cluster/subcluster-specific retention times
+- **Improved compression**: Transparent compression for job archive imports
+- **Parallel processing**: Parallelized Iter function in all archive backends
+
+### Job Tagging System
+
+- **Job tagger option**: Enable automatic job tagging via configuration flag
+- **Application detection**: Automatic detection of applications (MATLAB, GROMACS, etc.)
+- **Job classifaction**: Automatic detection of pathological jobs
+- **omitTagged flag**: Option to exclude tagged jobs from retention/cleanup operations
+
+### Archive Backends
+
+- **S3 backend**: Full support for S3-compatible object storage
+- **SQLite backend**: Full support for SQLite backend using blobs
+- **Performance improvements**: Fixed performance bugs in archive backends
+- **Better error handling**: Improved error messages and fallback handling
+
+## New features and improvements
+
+### Frontend
+
+- **Loading indicators**: Added loading indicators to status detail and job lists
+- **Job info layout**: Reviewed and improved job info row layout
+- **Metric selection**: Enhanced metric selection with drag-and-drop fixes
+- **Filter presets**: Move list filter preset to URL for easy sharing
+- **Job comparison**: Improved job comparison views and plots
+- **Subcluster reactivity**: Job list now reacts to subcluster filter changes
+- **Frontend dependencies**: Bumped frontend dependencies to latest versions
+- **Svelte 5 compatibility**: Fixed Svelte state warnings and compatibility issues
+
+### Backend
+
+- **Progress bars**: Import function now shows progress during long operations
+- **Better logging**: Improved logging with appropriate log levels throughout
+- **Graceful shutdown**: Fixed shutdown timeout bugs and hanging issues
+- **Configuration defaults**: Sensible defaults for most configuration options
+- **Documentation**: Extensive documentation improvements across packages
+
+### API improvements
+
+- **Role-based metric visibility**: Metrics can now have role-based access control
+- **Job exclusivity filter**: New filter for exclusive vs. shared jobs
+- **Improved error messages**: Better error messages and documentation in REST API
+- **GraphQL enhancements**: Improved GraphQL queries and resolvers
+
+### Performance
+
+- **Database indices**: Optimized SQLite indices for better query performance
+- **Job cache**: Introduced caching table for faster job inserts
+- **Parallel imports**: Archive imports now run in parallel where possible
+- **External tool integration**: Optimized use of external tools (fd) for better performance
+
+### Developer experience
+
+- **AI agent guidelines**: Added documentation for AI coding agents (AGENTS.md, CLAUDE.md)
+- **Example API payloads**: Added example JSON API payloads for testing
+- **Unit tests**: Added more unit tests for NATS API and other components
+- **Test improvements**: Better test coverage and test data
+
+## Bug fixes
+
+- Fixed nodelist paging issues
+- Fixed metric select drag and drop functionality
+- Fixed render race conditions in nodeList
+- Fixed tag count grouping including type
+- Fixed wrong metricstore schema (missing comma)
+- Fixed configuration issues causing shutdown hangs
+- Fixed deadlock when NATS is not configured
+- Fixed archive backend performance bugs
+- Fixed continuous scroll buildup on refresh
+- Improved footprint calculation logic
+- Fixed polar plot data query decoupling
+- Fixed missing resolution parameter handling
+- Fixed node table initialization fallback

+## Migration notes
 
-- You need to perform a database migration. Depending on your database size the
+- Review and update your `config.json` to use kebab-case attribute names
-  migration might require several hours!
+- If using NATS, configure the new `nats` and `api-subjects` sections
-- You need to adapt the `cluster.json` configuration files in the job-archive,
+- If using S3 archive backend, configure the new `archive` section options
-  add new required attributes to the metric list and after that edit
+- Test the new public dashboard at `/public` route
-  `./job-archive/version.txt` to version 2. Only metrics that have the footprint
+- Review cron worker configuration if you need different frequencies
-  attribute set can be filtered and show up in the footprint UI and polar plot.
-- Continuous scrolling is default now in all job lists. You can change this back
-  to paging globally, also every user can configure to use paging or continuous
-  scrolling individually.
-- Tags have a scope now. Existing tags will get global scope in the database
-  migration.

-- Enable to delete tags from the web interface
