# Changelog
## 2025-09-07 - 3.4.0 - feat(taskbuffer-dashboard)
Add TaskBuffer dashboard web component, demo and browser tests; add HTML entry and update dependencies
- Introduce a new web component taskbuffer-dashboard for real-time visualization of tasks and schedules (ts_web/taskbuffer-dashboard.ts).
- Add a demo wrapper and interactive UI for the dashboard (ts_web/elements/taskbuffer-dashboard.demo.ts).
- Provide web exports and typings for web usage (ts_web/index.ts) and include an HTML entry (html/index.html).
- Add browser-oriented tests to validate metadata structures for the web component (test/test.10.webcomponent.browser.ts).
- Bump package version to 3.3.0 in package.json as part of this change.
- Update/add dependencies and devDependencies (@design.estate/dees-element added; smartlog, @git.zone/tsbuild and @git.zone/tstest bumped).
## 2025-09-06 - 3.2.0 - feat(core)
Add step-based progress tracking, task metadata and enhanced TaskManager scheduling/metadata APIs
- Introduce TaskStep class for named, weighted steps with timing and status (pending|active|completed).
- Add step-tracking to Task: notifyStep, getProgress, getStepsMetadata, getMetadata, resetSteps and internal step lifecycle handling.
- Task now records runCount and lastRun; Task.run flow resets/cleans steps and aggregates progress.
- TaskManager enhancements: schedule/deschedule improvements, performDistributedConsultation, and new metadata-focused APIs: getTaskMetadata, getAllTasksMetadata, getScheduledTasks, getNextScheduledRuns, addExecuteRemoveTask (exec + collect report).
- Exports updated: TaskStep and related types exported from index, plus Task metadata interfaces.
- Comprehensive README updates documenting step-based progress tracking, metadata, TaskManager and examples.
- New/updated tests added for step behavior and metadata (test/test.9.steps.ts) and other TS additions.
- Minor build/script change: build script updated to use 'tsbuild tsfolders'.
## 2025-08-26 - 3.1.10 - fix(task)
Implement core Task execution flow, buffering and lifecycle; update README with generics and buffer docs
