release: v0.3.25 — Chromium 146.0.7680.177.3, launch_context_async, contextOptions

feat: add launch_context_async() + JS contextOptions escape hatch (#141 )
Python: add async counterpart to launch_context(). Forwards all kwargs to browser.new_context() — enables storage_state, permissions, extra_http_headers, etc. without needing a persistent profile folder. JS: launchContext() and launchPersistentContext() silently dropped unknown options. New contextOptions field in LaunchContextOptions is spread into newContext() to forward arbitrary Playwright context options (e.g. storageState, permissions, geolocation).

+## [Unreleased]
+
+## [0.3.25] — 2026-04-16
+
+- **[wrapper]** Python: add `launch_context_async()` — async counterpart to `launch_context()`. Returns a BrowserContext with all kwargs forwarded to `browser.new_context()`, enabling `storage_state`, `permissions`, `extra_http_headers`, etc. without a persistent profile folder. Closes #141.
+- **[wrapper]** JS: `launchContext()` and `launchPersistentContext()` silently dropped unknown options (including `storageState`). New `contextOptions` escape hatch forwards arbitrary options to Playwright's `newContext()`.
+- **[wrapper]** Fix `humanConfig` TypeScript typing (#151).
+- **[binary]** New build 146.0.7680.177.3 for Linux x64 + arm64 — 57 source-level fingerprint patches (up from 49): WebAuthn capabilities, AAC audio encoder, and window position spoofing; WebGL and canvas format consistency fixes; SOCKS5 warm connection pool auth fix for credentialed proxies.
+- **[docs]** Add recommended anti-bot config and SOCKS5 tips to troubleshooting.
+
+## [0.3.24] — 2026-04-10
+
+- **[wrapper]** Native SOCKS5 proxy support — pass `proxy="socks5://user:pass@host:port"` directly. Credentials handled natively by Chrome. Works across all launch functions, Python + JS.
+- **[wrapper]** Add Playwright ElementHandle humanize support — `element_handle.click()`, `.fill()`, `.type()` now use human-like behavior when `humanize=True` (thanks [@evelaa123](https://github.com/evelaa123), #133)
+- **[binary]** Upgrade Linux arm64 to Chromium 146.0.7680.177.2 (49 patches) — now matches Linux x64
+- **[binary]** New build 146.0.7680.177.2 for both Linux platforms: native SOCKS5 proxy with UDP ASSOCIATE (QUIC/HTTP3 over SOCKS5)
+- **[docs]** Clarify humanize requires wrapper import over CDP (#126)
+
+## [0.3.23] — 2026-04-09
+
+- **[wrapper]** Add full Puppeteer humanize support — human-like mouse, keyboard, and scroll behavior for `puppeteer-core` users (thanks [@evelaa123](https://github.com/evelaa123), #129)
+- **[wrapper]** Fix Playwright humanize gaps — `pressSequentially`, `tap`, `clear` on pages and frames now use human-like behavior (#129)
+- **[wrapper]** Expose humanize module for CDP-connected browsers — `import from 'cloakbrowser/human'` for manual patching of external Playwright instances (#126)
+- **[docker]** Fix `cloakserve` locale/timezone mismatch — CLI args now route through `build_args()` so the companion `--lang` flag is added automatically (#130)
+- **[meta]** Use Node 24 in CI publish workflow to work around broken npm in Node 22.22.2
+
+## [0.3.22] — 2026-04-09

+
+## [0.3.21] — 2026-04-07
+
+- **[wrapper]** Remove dead `--disable-blink-features=AutomationControlled` flag -- binary patch 009 already handles `navigator.webdriver` at source level
+- **[wrapper]** Remove hardcoded GPU vendor/renderer flags -- binary auto-generates diverse, realistic GPU profiles from the fingerprint seed. Each seed gets a unique GPU instead of every user sharing the same one
+- **[wrapper]** Allow `viewport=None` to disable viewport emulation in both Python and JS wrappers (thanks [@kitiho](https://github.com/kitiho), #107)
+- **[wrapper]** Enable `geoip=True` in stealth test example to fix FingerprintJS detection
+- **[meta]** Remove npm self-upgrade step in CI -- Node 22 ships with compatible npm

+- **JS `contextOptions` escape hatch** — forward arbitrary options (including `storageState`) to Playwright's `newContext()` from `launchContext()` / `launchPersistentContext()`.
+- **Native SOCKS5 proxy** — `proxy="socks5://user:pass@host:port"` works directly in all launch functions, Python + JS. QUIC/HTTP3 tunnels through SOCKS5 via UDP ASSOCIATE.
+- **Chromium 146 upgrade** — rebased all patches from 145.0.7632.x to 146.0.7680.177
+- **57 fingerprint patches** — additional detection-vector coverage (WebAuthn, AAC audio, window position) and WebGL/canvas consistency fixes
+- **WebRTC IP spoofing** — `--fingerprint-webrtc-ip=auto` resolves your proxy's exit IP and spoofs WebRTC ICE candidates. Auto-injected when using `geoip=True` (no extra network call)
+- **Proxy signal removal** — DNS/connect/SSL timing zeroed, proxy cache headers stripped, Proxy-Connection header leak removed

-"""Launch stealth Chromium as a CDP server for remote connections.
+"""CDP multiplexer — per-connection fingerprint seeds for stealth Chromium.
+
+Spawns a separate Chrome process per unique fingerprint seed, routing CDP
+connections through a single port. Each seed gets its own browser identity.

 Usage:
-    cloakserve                          # headless on port 9222
-    cloakserve --headless=false         # headed (uses Xvfb in Docker)
-    cloakserve --proxy-server=host:port # with proxy
+    cloakserve                                      # default, backward compat
+    cloakserve --port=9222                           # custom port

-Connect from host:
-    playwright.chromium.connect_over_cdp("http://localhost:9222")
+Client:
+    browser = pw.chromium.connect_over_cdp("http://host:9222?fingerprint=12345")
+    browser = pw.chromium.connect_over_cdp(
+        "http://host:9222?fingerprint=12345&timezone=America/New_York&locale=en-US"

+ *   move, click (with clickCount support for dblclick), wheel,
+ *   dragAndDrop
+ *
+ * KEYBOARD:
+ *   type, down, up, press, sendCharacter
+ *
+ * FRAME-LEVEL:
+ *   click, hover, type, select, focus, tap
+ *   + $, $$, waitForSelector (return patched ElementHandles)
+ *
+ * ELEMENTHANDLE-LEVEL (Puppeteer-specific, no Playwright equivalent):
+ *   click (with clickCount), hover, type, press, tap, select,
+ *   focus, drop, dragAndDrop
+ *   + $, $$, waitForSelector (nested elements are also patched)
+ *
+ * BROWSER-LEVEL:
+ *   newPage, createBrowserContext / createIncognitoBrowserContext,
+ *   targetcreated event
+ *
+ * Stealth-aware:
+ *   - isInputElement / isSelectorFocused use CDP Isolated Worlds
+ *   - Shift symbol typing uses CDP Input.dispatchKeyEvent (isTrusted=true)
+ *   - ElementHandle isInput check uses CDP DOM.describeNode (no JS execution)
+ *   - Falls back to page.evaluate only when CDP session is unavailable
+ *
+ * Puppeteer-specific adaptations:
+ *   - page.createCDPSession() instead of context.newCDPSession(page)
+ *   - page.viewport() instead of page.viewportSize()
+ *   - page.$(selector) instead of page.locator(selector)
+ *   - keyboard.sendCharacter() mapped via RawKeyboard.insertText
+ *   - mouse.wheel({deltaX, deltaY}) object form adapted to (dx, dy)
+ *   - page.select() instead of page.selectOption()
+ *   - ElementHandle prototype patching (Puppeteer-only)
+ *   - No page.dblclick() — Puppeteer uses click({clickCount:2})

Author	SHA1	Message	Date
CloakHQ	4459f66593	release: v0.3.25 — Chromium 146.0.7680.177.3, launch_context_async, contextOptions	2026-04-16 22:24:36 +02:00
CloakHQ	ce8b92ba4f	feat: add launch_context_async() + JS contextOptions escape hatch (#141 ) Python: add async counterpart to launch_context(). Forwards all kwargs to browser.new_context() — enables storage_state, permissions, extra_http_headers, etc. without needing a persistent profile folder. JS: launchContext() and launchPersistentContext() silently dropped unknown options. New contextOptions field in LaunchContextOptions is spread into newContext() to forward arbitrary Playwright context options (e.g. storageState, permissions, geolocation).	2026-04-16 21:30:40 +02:00

CloakHQ	cb0b87873e	feat: native SOCKS5 proxy support in proxy= parameter Route SOCKS5/SOCKS5h proxies via --proxy-server Chrome arg instead of Playwright's proxy dict (which rejects SOCKS5 with credentials). Handles string URLs, Playwright dicts, IPv6, bypass lists. SOCKS5 geoip exit IP resolution uses socks-proxy-agent (optional peer dep). Falls back to DNS if not installed.	2026-04-10 22:20:16 +02:00

lilosandGitHub	7afe59435e	feat: Add Puppeteer humanize support and fix Playwright humanize gaps (#129 ) - Add full Puppeteer humanize implementation (page, frame, element handle patching) - Fix critical Playwright gaps: page.pressSequentially, page.tap, page.clear - Fix frame-level patching: frame.pressSequentially, frame.tap - Add comprehensive stealth tests for Puppeteer - Update SLOW test suite to use correct humanize: true API - Add 4 new tests validating fixed Playwright methods	2026-04-09 20:49:20 +02:00
CloakHQ	1cef71133d	fix(test): clear CLOAKBROWSER_BINARY_PATH in puppeteer mock tests Env var override takes precedence over ensureBinary mock, causing test to fail in Docker where the var is always set.	2026-04-09 20:45:16 +02:00
CloakHQ	7a0937cc54	feat(js): expose humanize module for CDP-connected browsers (#126 ) Add ./human export path to package.json so users can import patchBrowser, patchPage, and resolveConfig to humanize CDP-connected Playwright instances.	2026-04-09 18:06:29 +02:00
CloakHQ	5b00ff0325	fix(cloakserve): route locale/timezone/seed CLI args through build_args() CLI args like --fingerprint-locale were passed as raw passthrough args to Chrome, missing the companion --lang flag that build_args() normally adds. Caused Intl API to default to en-US while navigator.language showed the correct locale — a detectable mismatch. Fixes #130	2026-04-09 17:58:47 +02:00

The upgrade step was removed in `02359f6` but is required for provenance-based publishing. Pin to npm@11 instead of @latest to avoid future breakage.	2026-04-07 07:31:08 +02:00
CloakHQ	06d77e7261	refactor: remove dead stealth args, let binary handle GPU diversity Remove --disable-blink-features=AutomationControlled (dead, binary handles navigator.webdriver at source level) and hardcoded GPU vendor/renderer flags. Binary auto-generates diverse GPU profiles from fingerprint seed. Improves fingerprint diversity -- previously every user shared the same GPU string. Bump to v0.3.21.	2026-04-07 07:16:22 +02:00
CloakHQ	211bd93d3e	fix(docker): install geoip2 in Docker image geoip=True raised ImportError inside the container because geoip2 was not installed. Added [geoip] extra to pip install.	2026-04-07 06:37:14 +02:00
CloakHQandkitiho	1060772734	fix: allow null viewport in Python wrapper (mirrors #107 ) viewport=None now disables viewport emulation via Playwright's no_viewport=True, matching the JS wrapper's viewport: null behavior. Uses a sentinel to distinguish "not provided" from explicit None. Co-authored-by: kitiho <51785099+kitiho@users.noreply.github.com>	2026-04-07 05:14:01 +02:00

CloakHQ	02359f69c8	ci: remove npm self-upgrade step — Node 22 ships with compatible npm	2026-04-06 02:08:44 +02:00
CloakHQ	a0c7704c4b	release: v0.3.20 — 48 patches, WebRTC IP spoofing, proxy signal removal	2026-04-06 01:54:35 +02:00
lilos	ccda93669e	feat(humanize): implement CDP Isolated Worlds and trusted keyboard events (fixes #110 )	2026-04-06 01:43:46 +02:00
CloakHQ	eb4efef329	feat: add --fingerprint-webrtc-ip flag with auto-resolve support Two ways to spoof WebRTC ICE candidate IPs: 1. --fingerprint-webrtc-ip=auto in args: resolves proxy exit IP via HTTP call through the proxy (ipify.org). No extra deps needed. 2. geoip=True: auto-injects the flag for free (exit IP already resolved during timezone/locale lookup, zero extra network cost). Explicit IP (--fingerprint-webrtc-ip=1.2.3.4) also supported. User-provided values always take precedence. Python + JS wrappers, README docs, tests.	2026-04-06 01:16:10 +02:00
CloakHQ	25d34dcea3	feat(cloakserve): add connection tracking, configurable data dir, better status endpoint - Move `import websockets` to top-level (guaranteed by [serve] extra) - Add --data-dir flag with smart default (Docker → /tmp/cloakserve, bare metal → ~/.cloakbrowser/cloakserve) - Store launch params (tz/locale/proxy) on ChromeProcess for conflict logging - Enhance GET / to return per-process detail (pid, port, seed, connections, config) - Add connection refcounting in WS handlers for status visibility - Add first-launch-wins note to README - Add tests for data-dir, Docker detection, and connection tracking	2026-04-05 22:41:33 +02:00
CloakHQ	c9e4f58353	feat: rewrite cloakserve as CDP multiplexer with per-connection fingerprint seeds Spawns a separate Chrome process per unique fingerprint seed, all behind a single port (9222). Clients specify seeds and fingerprint params via query string on the CDP URL: connect_over_cdp("http://host:9222?fingerprint=12345&timezone=Asia/Tokyo") Supports all --fingerprint-* flags as query params, geoip=true for auto timezone/locale from proxy IP, and proxy= for per-process proxies. - Rewrite bin/cloakserve from 57-line wrapper to aiohttp CDP multiplexer - Add ChromePool with per-seed process management and port allocation - Bidirectional WebSocket proxy for CDP traffic - URL rewriting for /json/version, /json/list, and WS paths - Rename _build_args -> build_args, _maybe_resolve_geoip -> maybe_resolve_geoip - Add aiohttp + websockets to serve optional deps - Dockerfile installs .[serve] extras - Add 20 unit tests for cloakserve (param parsing, CLI args, URL rewriting)	2026-04-05 22:30:18 +02:00
