## v0.5.0 - 2026-05-12

- <a href="https://github.com/nxdun/rust-codebase/pull/14" target="_blank"><code>#14</code></a>[feat(infra)] Add Prometheus and Grafana observability stack
  - Introduces a full observability layer using Prometheus and Grafana across local dev and production environments.
  - Instruments core `ytdlp` services (tracking job lifecycle and processing duration) and `captcha` security middleware (tracking verification hits, failures, and API key bypasses).
  - Automates provisioning of "Worker Health" and "Security" dashboards as code.
  - Implements Caddy `@internal_only` global matcher to protect `/metrics`, `/nadun/fs/*`, and `/nadun/grafana/*` endpoints across all environments.
  - Standardizes `docker-compose.dev.yml` to use production-style image builds, resolving stale binary linking issues in Alpine/musl environments.
  - Updates Makefile, Terraform, and Cloud-init to handle automated fetching of all observability artifacts.

- <a href="https://github.com/nxdun/rust-codebase/pull/13" target="_blank"><code>#13</code></a>[fix(ytdlp)] Stabilize progress streaming and temp file handling
  - Updates the `yt-dlp` download flow to send an immediate SSE snapshot so clients receive the current job state on connect.
  - Downloads now use per-job temp directories before safely moving completed files to the final output path.
  - Fixes cleanup behavior for failed and timed-out jobs by removing temp artifacts directly.
  - Refactors `aria2` progress parsing to use targeted regex extraction and simpler helpers.
  - Updates the health endpoint to return the service version.
  - Rewrites and reorganizes README, TOC, workflow, and architecture diagrams to match current system design.

## v0.4.0 - 2026-04-25

- <a href="https://github.com/nxdun/rust-codebase/pull/11" target="_blank"><code>#11</code></a>[feat(backend)] Add GitHub contributions API endpoint
  - New `GET /api/v1/contributions` endpoint returning GitHub-style calendar data (cells, months, legend, summary, metadata).
  - New `ContributionsService` with GitHub GraphQL integration and 24h in-memory caching.
  - API controller enforces default-only access for `/api/v1/contributions?username=` (only the configured default `GITHUB_USERNAME`/`GITHUB_PAT` is permitted).
  - Full `ContributionsResponse` model matching GitHub calendar schema (remains unchanged).
  - Env config support for `GITHUB_PAT` and `GITHUB_USERNAME`; cloud-init template updated to pass `GHCR_PAT` as `GITHUB_PAT` (remains unchanged).
  - Postman collection includes a negative test asserting requests with non-default usernames are rejected (rejection test rather than a supported feature).
  - Test state and config updates for contributions service.

## v0.3.1 - 2026-04-19

- <a href="https://github.com/nxdun/rust-codebase/pull/10" target="_blank"><code>#10</code></a>[refactor(api)] Standardize API errors and simplify service flows
  - Unified all API errors under a shared `AppError` enum with structured JSON responses.
  - Removed unnecessary `async` from `YtdlpManager` service methods.
  - `MASTER_API_KEY` missing now exits cleanly with code 1 instead of panicking.
  - Root endpoint returns JSON instead of plain text.
  - Added custom Caddy file browser with neon dark theme, served to infra by makefile and terraform via presigned R2 URL.
  - Bumped `axum` to 0.8.9, `tokio` to 1.52; added `thiserror` 2.0.

## v.0.3.0 - 2026-03-31

- <a href="https://github.com/nxdun/rust-codebase/pull/9" target="_blank"><code>#9</code></a>[feat(infra)] Tiered rate limiting, Caddy file server, and expanded test suite
  - Yt Download Support Removed Due to DMCA Sorry ;[
  - Added API Key Support With Tiered Rate Limiting (free vs. premium).
  - Added Production Caddyfile with Personal File Server + Reverse Proxy.
  - Infrastructure Fully Parameterized with Environment Variables and Config Files.
  - Test Cases Are More Rigorous and Cover Edge Cases.
  - Postman Collection is More Structured With Up to Date Seperation and Usage of environment variables.

## v0.2.0 - 2026-03-27

- <a href="https://github.com/nxdun/rust-codebase/pull/8" target="_blank"><code>#8</code></a>[feat(ytdlp)] Add streaming progress and supported sites API
  - SSE endpoint for live yt-dlp job download progress updates.
  - Added supported sites endpoint listing all available download platforms.
  - Replaced bgutil/POT provider with `aria2c` for faster multi-connection downloading.
  - Introduced `MASTER_API_KEY` auth middleware; replaces dev bypass header.
  - **Breaking:** `YTDLP_COOKIES_FILE`, `YTDLP_POT_PROVIDER_URL`, and `YTDLP_PRESIGNED_URL` env vars removed. YouTube Shorts URL normalization removed.

  - Added HTTPS support via Caddy reverse proxy with automated TLS certificate provisioning.
