Release v0.3.5 – Daily Standup Management & Production Migrations

Release Date: January 27, 2026
Target Branch: main
Source Branch: dev
Status: Ready for production deployment

1. Overview

Release v0.3.5 delivers a production-ready Daily Standup Management system for distributed teams and a robust database migration framework to safely evolve the schema over time. The release is designed to be 100% backward compatible with the previous version (v0.3.0), with a strong focus on stability, observability, and maintainability.

2. Highlights

2.1 Daily Standup Management System

New functionality to support daily standups and team coordination:

Standup entries with:
- Did / Doing / Done
- Blockers
- Challenges
- References / links
Per-agent, per-day standup records with uniqueness guarantees
Agent heartbeat tracking for health/online status
RESTful APIs for CRUD operations and querying standups
Frontend views for standup creation, editing, and overview

2.2 Production-Grade Migration System

A new migration mechanism to safely evolve the database schema:

Transactional migrations (all-or-nothing)
Migration tracking table to avoid re-applying the same migration
Idempotent, deterministic execution
Helper scripts to create and bootstrap migrations
Designed to be safe in containerized / concurrent environments

3. Changes Summary

3.1 Backend

Features:

Added models and handlers for:
- daily_standups – stores daily standup data per agent
- agent_heartbeats – stores heartbeat events/status
Added endpoints (examples, may vary by implementation):
- POST /api/standups – create/update standup (UPSERT)
- GET /api/standups – list standups with filters (project, agent, date)
- GET /api/standups/{id} – get single standup
- PUT /api/standups/{id} – update standup
- DELETE /api/standups/{id} – delete standup
- POST /api/heartbeats – record heartbeat
- GET /api/agents/{id}/heartbeats – list heartbeats for an agent

Migration framework:

New schema_migrations table to track executed migrations
Migrations executed transactionally on startup
Skips already-applied migrations based on version identifiers

3.2 Database Schema

New tables (conceptual schema):

-- Daily standups
CREATE TABLE daily_standups (
    id UUID PRIMARY KEY,
    agent_id UUID NOT NULL,
    project_id UUID NOT NULL,
    standup_date DATE NOT NULL,
    did TEXT,
    doing TEXT,
    done TEXT,
    blockers TEXT,
    challenges TEXT,
    references TEXT,
    created_at TIMESTAMP,
    updated_at TIMESTAMP,
    UNIQUE (agent_id, standup_date)
);

-- Agent heartbeats
CREATE TABLE agent_heartbeats (
    id UUID PRIMARY KEY,
    agent_id UUID NOT NULL,
    heartbeat_time TIMESTAMP NOT NULL,
    status TEXT DEFAULT 'active',
    metadata JSONB,
    created_at TIMESTAMP
);

-- Migration tracking
CREATE TABLE schema_migrations (
    id SERIAL PRIMARY KEY,
    version VARCHAR(255) UNIQUE NOT NULL,
    applied_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Indexes (recommended):

CREATE INDEX idx_standups_agent_id
    ON daily_standups (agent_id);

CREATE INDEX idx_standups_project_date
    ON daily_standups (project_id, standup_date);

CREATE INDEX idx_heartbeats_agent_id
    ON agent_heartbeats (agent_id);

CREATE INDEX idx_heartbeats_time
    ON agent_heartbeats (heartbeat_time);

4. Frontend

New Standups view (dashboard) for:
- Viewing standups by project/agent/date
- Navigating through historical standups
New Standup modal/form for:
- Creating and editing standups
- Writing content using markdown
State management/store updated to:
- Load, cache, and update standup data
- Handle loading/error states
XSS protection for rendered markdown (e.g. DOMPurify or equivalent)

5. Scripts & Tooling

New scripts to manage migrations (names may vary; examples):
- create-migration – scaffold a new migration with auto-incremented version
- bootstrap-migrations – bootstrap an existing database into the migration system
Startup logic:
- Runs all pending migrations on app start
- Logs migration versions and timing

6. Quality & Testing

Unit tests: All existing tests passing, new tests added for:
- Standup creation, update, and querying
- Heartbeat recording and listing
- Migration application logic
Integration tests: Exercise API flows for:
- Creating standups
- Listing standups with filters
- Recording and listing heartbeats
Static checks: Linters / analyzers (go vet or equivalents) are clean
Performance: Endpoint latencies verified to be within acceptable limits for typical payload sizes

7. Backward Compatibility

No breaking changes:
- Existing endpoints remain unchanged
- No removals of existing tables/columns
- New tables and endpoints are additive
The migration framework:
- Only adds schema; does not drop or alter existing required fields in a breaking way
- Is safe to run on existing databases after bootstrap

8. Deployment Notes

8.1 Prerequisites

Database access with permissions to:
- Create tables
- Create indexes
- Insert into migration tracking table
Ability to restart application services

8.2 Upgrade Steps (from previous version)

Update code and pull latest main:

git checkout main
git pull origin main

For existing databases:

If migration tracking does not exist yet, run the bootstrap script once (if provided in your repo):
```
# Example; adjust path/name to your repo
./scripts/bootstrap-migrations.sh
```

Restart services to apply migrations:

docker-compose down
docker-compose up -d

or, if running directly:

systemctl restart <service-name>
# or
./your-binary

Verify health:

Call health endpoint (if available), for example:
```
curl http://<host>:<port>/health
```

Verify standups module:

Open the UI and ensure the new Standups section is visible
Create a test standup and check it persists as expected

9. Security Considerations

Input validation added/updated on new endpoints
Standup markdown rendering is sanitized to mitigate XSS
SQL operations use parameterized queries
Important for production:
- Ensure authentication/authorization is enabled for standup endpoints
- Serve the application over HTTPS
- Consider rate limiting and logging/monitoring for the new APIs

10. Known Limitations / Future Work

No built-in analytics yet for standups (e.g., trends, metrics per team)
Heartbeat data currently provides basic status; richer status/health dashboards can be added later
Migrations are focused on schema; data migrations might need additional conventions or tooling in future versions

11. Summary

Release v0.3.5 is a safe, backward-compatible update that introduces:

A complete daily standup management flow (backend + frontend)
A production-grade migration system for long-term maintainability
Additional tests and safeguards to keep the codebase stable

This version is recommended for deployment to main as the baseline for future feature work.

This view still renders standup.references, but the backend now returns reference_links. Update the view (and any related store normalization) to use the new field, or map/alias the API response so existing UI continues to work.

The advisory lock is acquired/released via db.QueryRow/db.Exec on a pooled *sql.DB. Advisory locks are session (connection) scoped, so acquiring on one connection and unlocking on another can leak the lock (or fail to actually serialize migrations). Use a dedicated *sql.Conn (db.Conn(ctx)) or a single transaction/connection to acquire and defer-unlock on the same session, and close the conn when done.
