v1.2.0

Summary

Add Tree Explorer — a new hierarchical view tab for navigating deeply nested config diffs.

Features

• Tree tab added as 3rd tab (Semantic → Raw Diff → Tree → Summary) with keyboard shortcut 3
• Hierarchical tree view — expands/collapses nested config nodes with chevron toggles
• Aggregated stats — branch nodes show compact change count badges (+N ~N -N)
• Risk indicators — risk severity dots bubble up from leaves to parent nodes
• Expand All / Collapse All controls for quick navigation
• Smart defaults — top-level nodes expanded, deeper levels collapsed
• Secret masking — leaf values respect the Mask Secrets toggle
• Graceful degradation for flat configs (.env) — renders as a single-level tree
• New types: TreeNode, TreeNodeStats, ResultsTab
• Pure utility buildTree() in app/utils/diff/tree.ts (Web Worker compatible)

v1.1.1

Fixes

• Sample dropdown z-index — "Try a sample" popover no longer appears behind CodeMirror editors
• Risk sidebar overflow — added overflow-hidden to prevent long content from escaping card boundaries
• Word breaking in risk labels — label text now uses break-words instead of break-all, preventing mid-word breaks like "w" / "as" on separate lines

v1.1.0

Summary

Phase 1 MVP complete — configspot now has full export, keyboard shortcuts, format-specific samples, syntax highlighting, and a smart summary view.

Features

• Smart Summary view — structured breakdown of Added, Removed, and Changed keys with values
• Export — Copy Raw Diff, Copy Summary, Copy Markdown Table, and Download HTML Report (self-contained dark-themed file)
• Keyboard shortcuts — Ctrl+Enter to compare, s to toggle secret masking, 1/2/3 to switch tabs, ? for help overlay
• Keyboard help button in header for discoverability
• Format-specific samples — "Try a sample" dropdown with .env, JSON (tsconfig), YAML (docker-compose), TOML (Cargo.toml), INI (MySQL config)
• CodeMirror syntax highlighting — JSON and YAML language extensions load based on selected format

Fixes

• Risk sidebar layout — long key names now wrap properly with break-all instead of overflowing the card
• Favicon — removed default Nuxt favicon.ico so custom SVG favicon is served correctly

v1.0.3

Features

• Added SVG favicon with gradient "C" logo (cyan → pink on dark background)
• Added cyan/pink accent colors on hero subtitle keywords ("Order-independent" and "key changes matter")
• Added /release skill for automated release workflow

Docs

• Added .claude/skills/release/SKILL.md for consistent release process

v1.0.2

Changes

• Added OpenGraph image (og.png) with gradient logo, tagline, format badges, and domain
• Added og:image, og:url, twitter:image meta tags pointing to configspot.edufalcao.com
• Added canonical link
• Added URL to JSON-LD structured data
• Updated hero subtitle to clarify order-independent comparison

v1.0.1

Changes

• Footer redesigned: centered "configspot by Eduardo Falcão" with dual links
  • "configspot" (cyan) links to the GitHub repository
  • "Eduardo Falcão" (pink) links to edufalcao.com
• Bumped footer font size from text-xs to text-sm

v1.0.0 — Initial Release

configspot v1.0.0

Config comparison and validation tool for developers. Compare .env, JSON, YAML, TOML, and INI files with semantic diffs, risk detection, and secret masking.

Features

• Multi-format parsing — .env, JSON (with comments), YAML, TOML, and INI with auto-detection from content heuristics
• Semantic diff engine — compares configs by key path, detecting added, removed, and changed entries beyond plain text diffs
• Risk classification — 9 heuristic categories (credentials, URLs, ports, feature flags, dependency versions, boolean flips, thresholds, removed keys, placeholders) with severity levels (info, review, high)
• Secret detection & masking — recognizes JWTs, AWS keys, GitHub tokens, base64 strings, and credential-like key names; masks values by default
• Raw diff view — unified text diff alongside the semantic view
• Shareable URLs — persist comparisons to Cloudflare D1 with short links and delete tokens
• Dark/light themes — terminal-chic design system with Space Grotesk, DM Sans, and JetBrains Mono typography
• CodeMirror editors — syntax-aware input with line numbers, drag-and-drop, and file upload
• "Try it" demo — one-click sample comparison for instant value demonstration
