 All notable changes to this project will be documented in this file.
 
+## [0.5.0] - (2026-03-22)
+
+### Added
+
+- Compression middleware (gzip/brotli) for API responses to reduce bandwidth
+- Plugin installation prompt system with per-vault trust flags
+- Versioning system with cache-busting query parameters on script URLs
+- Option to install ignis-bridge plugin to vaults imported at runtime
+
+### Changed
+
+- Auto-creation of default vault now requires `AUTO_CREATE_DEFAULT=true` environment variable
+- Script URLs (`ignis-ui.js`, `shim-loader.js`) now include version query params for automatic cache invalidation
+- Cache headers: versioned assets cached for 1 year, non-versioned for 5 minutes
+
+### Fixed
+
+- Vault manager not displaying when no vaults exist
+- `window.close()` now shows vault manager when no vault is configured
+
+### Removed
+
+- Unused `VAULT_PATH` environment variable fallback logic
+
 ## [0.4.0] - Basil (2026-03-18)

+- `zlib` shim using `pako` library for compression/decompression operations (deflate, inflate, gzip, gunzip, etc.)
+- File descriptor operations: `fs.open()`, `fs.read()`, `fs.close()`, `fs.fstat()` and sync variants
+- `fs.promises.open()` returning FileHandle objects with `stat()`, `read()`, `close()` methods
+- `showOpenDialog` electron dialog shim with browser file picker and vault upload
+- `showOpenDialogSync` hacky workaround using file staging registry and two-step upload flow
+- Enhanced `Buffer` shim with `alloc()`, `allocUnsafe()`, `byteLength()`, and `isEncoding()` methods
+
+### Fixed
+
+- `MessageDialog` modal dismiss error when confirm button clicked
+- Dialog shim modal event ordering to prevent null reference errors

+## [0.6.1] - Slifer (2026-03-24)
+
+### Added
+
+- `fetch()` shim that proxies cross-origin requests through `/api/proxy` to bypass CORS restrictions
+- Automatic `Origin: app://obsidian.md` header injection for cross-origin requests to match Obsidian desktop app
+- User-Agent forwarding from browser to proxy for cross-origin requests

+### Fixed
+
+- Obsidian Sync API authentication now works in browser (was blocked by CORS)
+- Proxy response headers cleaned to exclude hop-by-hop headers (`content-encoding`, `transfer-encoding`, `content-length`, `connection`)
