This is an update of our Aura plans first explained in [1] and then in [2]. Please read those if you don't know what Aura is.
 
At that point we didn't have a timeline but now we do. We are trying to ship Aura on Windows in m32. The main issue is performance but we are making fast progress towards parity on that front. As in any release we are metrics driven; if we don't meet the speed, stability, security metrics we simply don't ship.
 
Aura is a grand unification of our graphics and UI stack that has significant implications. Here are the ones that you want to be aware of:
 
1- For Win7 and Win8 machines with capable video hardware and relatively new drivers, Aura fully uses the GPU.
This might lead to issues for some users with non standard configurations. We are increasing the test efforts to include varied hardware but we don't expect to catch every bug.
 
2- For WinXP and Vista users we will always use the software-only path. 
A lot of the performance work we are doing is related to make this mode as fast as it is in m31. However, in the short term we expect to use more CPU cycles and more memory than m31. Part of it is just a trade-off between scrolling performance and use of resources. We'll work to refine our stack in upcoming releases so we only pay the price for the things we really care about.
 
3- We have an automatic mechanism to switch Chrome from the GPU path to software path if we detect trouble.

It is nearly instantaneous in the case where the GPU process crashes. However, if the GPU process hangs it takes longer for Chrome to detect this condition, and of course BSODs are not something that we can prevent in most cases.
 
4- Opt-in or out.
In the short term users can opt-in or out from GPU acceleration from the settings menu -> system -> Use hardware acceleration. This setting will go away for XP and Vista users
once we switch to use DX11 because that is not available on those releases. We don't have a timeline for that yet.
 
5- WebGL and Pepper Flash.
If Aura is in software mode (for XP users for example) both WebGL and Pepper flash are also in software mode. This means that Flash's stage 3D [3] is unavailable. In previous versions of Chrome we could tolerate some parts of the page using hardware acceleration and others not using it but that is not practical with Aura. In the case of Flash the user can switch to NPAPI flash (for now, NPAPI is going away by the end of 2014) or Opt-in into hardware acceleration.
 
6- Windows 8 mode and Ash.
Ash is the Aura Shell [4]. Which most people know as the ChromeOS windowing environment. Aura implies Ash, so we decided to use Ash as our shell environment for Windows 8 metro mode. We are currently experimenting on how much of the shell we expose in Windows 8 mode, but even if Chrome m32 looks like m31 in metro mode Ash will still be running under the covers.
 
7- Linux and Mac.
The plan of record is to move Linux Chrome to Aura in m33. There are no plans to move Mac to Aura.
 
8- Legacy UI/ Graphics stack.
It will be removed from the codebase once there are no clients . If the current plans hold, it means it will be removed before we branch for m34.

Does that mean "tagging" system is coming in Bookmarks:

 

 

 

Experimental bookmark model based on tags. This CL introduces a BookmarTagModel class. BookmarTagModel provides a way to access and manipulate bookmarks in a non-hierarchical way. BookmarkTagModel view the bookmarks as a flat list, and each one can be marked with a collection of tags (tags are simply strings). BookmarkTagModel converts on demand the data from an existing BookmarkModel to its view of the world by considering all the titles of all the ancestors as tags. This view is frozen on an individual bookmarks when the BookmarkTagModel performs a change on the tags of this bookmarks. The Bookmark's meta info is used for storage. An observer may be attached to a BookmarkTagModel to observe relevant events. BUG=None Review URL: https://codereview.chromium.org/26894002

For those running the dev channel, today's update fixes problems in the previous update with the Syzy thingamabob which resulted in all extensions breaking. Extensions work once again.

 

Not sure whether those problems were just on my end, but it seems the Syzy thing caused major problems elsewhere.

Oh yes, another bug with the Chrome OS implementation. If you're running dual display, and minimise the browser window inside the Chrome OS frame on a smaller display, it'll attempt to maximise to the primary display's resolution, bugging it out.

So on a 1440x900 display, Chrome attempts to maximise to 1920x1080. :rofl:

And the black screen bug is now fixed on my machine.

Google must believe bigger is better! I wanted to say "Well everything is bigger in Texas" but u don't live there sooo I'll run with previous

I made a bug report for the annoying flash bugs in chrome regarding multi monitor setups and fullscreen mode: Would be awesome if some people in here could test, star and confirm this issue for me: https://code.google.com/p/chromium/issues/detail?id=317532 Thanks!

Iron is a known scam/scareware. People get so paranoid about Google spying on you in Chrome without researching.

You're better off disabling all the privacy-offending features in Chrome if they're really an issue or just use Chromium.

DirectWrite coming.... Yuppee!!!

 

https://code.google.com/p/chromium/issues/detail?id=25541#c57

 

 

Expose the DirectWrite RuntimeEnabledFeature to WebRuntimeFeatures to
allow it to be set from chrome. This in turn will allow us to add a
--direct-write command line flag for the experimental DirectWrite font
rendering support.

    • Microsoft is making Windows 11's context menus faster, simpler, and configurable

      That's (at least partially) on 7-zip; Nanazip (7-zip fork) adds itself properly to Context menus.
    • Ads have been turned off in the forums

      By Steven P. · Posted

      We have disabled advertising in the forums for now for an undetermined period. If you feel like you get a lot of value out of the site please do whitelist ads on the news articles, and/or consider getting a subscription, we offer two tiers, one at: $14 per year (support the site for just over a dollar a month) or the $28/year tier (just over $2/month) that disables advertising and affiliate link tracking throughout the site (so also on the news side). We also have a 'Buy us a coffee' page if you just want to make a one-time donation. I am not mincing words when I say it is becoming harder and harder to monetize publications like Neowin, it's a fact of life that when we can no longer afford to pay for everything we'll go like many other sites already have. It doesn't have to cost you anything There are other ways to support Neowin too, like posting on topic content in the forums (technical support/questions/helping others) and sharing our news articles.. this costs nothing but your time and is just as important as subscribing or making a monetary donation! Anyway thanks for your time and continued support of Neowin. Now in our 26th year, and hopefully many more! For all the lurkers out there that whitelist us, make a free member account, and see fewer (only inline) ads on the news side  
    • BATorrent 3.0.2

      By Copernic · Posted

      BATorrent 3.0.2 by Razvan Serea BATorrent is a lightweight, open-source BitTorrent client built with modern C++ and Qt 6, offering a clean, fast, and privacy-focused alternative to traditional torrent apps. It supports magnet links, .torrent files, resume data, sequential downloading, per-file priorities, and even imports from qBittorrent. Power users benefit from integrated RSS auto-download with regex filtering, duplicate detection, and automatic tracker lists from Stremio. Streaming is seamless thanks to auto-detected players like VLC and IINA. BATorrent includes robust VPN tools—interface binding, auto-detection for WireGuard-based services like Mullvad and NordLynx, kill switch, proxy support, and IP filtering. A full WebUI enables remote control, while integrations with Plex, Jellyfin, and Emby automate library updates. With themes, speed scheduling, system-tray alerts, and cross-platform support for Windows, Linux, and macOS, BATorrent delivers a polished, high-performance torrenting experience. BATorrent features: Core .torrent file and magnet link support Resume data — picks up where you left off after restart Import torrents from qBittorrent Create .torrent files from any file or folder Sequential download mode Per-file priority control (skip, low, normal, high) Seed ratio limits with auto-pause DHT, PEX, UPnP, NAT-PMP RSS Auto-Download Subscribe to RSS feeds — automatically download new torrents as they appear Regex filters — match only what you want (e.g. 1080p|720p, S01E\d+) Per-feed settings — custom save path, check interval (5–1440 min), enable/disable Auto-download — matched items are downloaded automatically in the background Supports magnet links, .torrent URLs, and tags Tray notifications when items are auto-downloaded Duplicate detection — never downloads the same item twice Stremio Stremio Addon System pre-installed — works out of the box Auto tracker list from ngosang/trackerslist Streaming Play while downloading — stream video files before the download is complete Supports mp4, mkv, avi, mov, wmv, flv, webm, m4v, ts Auto-detects installed players (VLC, IINA, system default) VPN & Privacy Interface binding — lock torrent traffic to a specific network interface (e.g. tun0) Auto VPN detection — identifies VPN interfaces (tun, tap, WireGuard, Mullvad, NordLynx, ProtonVPN) Kill switch — automatically pauses all torrents if the VPN interface drops Auto-resume — resumes only the torrents paused by the kill switch when VPN reconnects Proxy support — SOCKS5 and HTTP proxy with optional authentication IP filtering — load P2P blocklists to block unwanted IP ranges Protocol encryption (enabled / forced / disabled) WebUI Remote management — control torrents from any browser at http://localhost:8080 REST API with JSON responses Add torrents via magnet link or .torrent upload Pause, resume, remove torrents remotely View peers and files per torrent Dark theme matching the desktop app HTTP Basic Auth with SHA-256 password hashing Configurable port and remote access (localhost vs 0.0.0.0) Interface 3 themes: Dark, Light, Midnight (bat/vampire aesthetic) Real-time speed graph Detailed panel with tabs: General, Peers, Files, Trackers Filter bar: search by name, filter by state (Active, Downloading, Seeding, Paused, Finished) Drag & drop .torrent files and magnet links Drag & drop reorder in torrent list System tray with notifications (download complete, kill switch events, RSS auto-downloads) Splash screen with bat animation Bilingual: English and Portuguese (BR), auto-detected from system locale Bandwidth Scheduler Alternative speed limits — set different download/upload limits on a schedule Time range — configure active hours (e.g. 01:00 to 07:00), supports overnight ranges Per-day control — choose which days of the week the schedule applies Automatically switches between normal and alternative speeds Media Server Integration Plex — automatically trigger library scan when a download completes Jellyfin / Emby — same automatic library refresh via API Configure server URL and authentication token/key in Settings System Cross-platform: Windows, Linux, macOS Auto-shutdown — automatically shut down PC when all downloads complete (60s cancellable countdown) Auto-update system (AppImage on Linux, installer on Windows, DMG on macOS) CLI arguments: pass .torrent files or magnet: URIs directly Keyboard shortcuts: Space to toggle pause, Ctrl+A to select all, Ctrl+O to open BATorrent 3.0.2 changelog: Phone pairing & WebUI The browser WebUI was reskinned to match the desktop app — same dark palette, Inter font, flat surfaces, the real BATorrent logo (it was a random bat before), and a proper magnet icon. It now looks like the same product, not a separate dashboard. Pairing is one tap and zero typing: the generated WebUI password is now copyable, and the QR code carries the credentials — scanning it from your phone logs straight in (no typing the IP or password), then drops the credentials from the address bar. Search Two new providers: RuTor (CIS sources, no login, via a public TorAPI relay) and Torrents-CSV. Results are sorted by seeders (healthiest first), and each search now times out after 15 s so one dead provider can't hang the UI. Files & trackers Per-file priority is back: right-click a file in the detail panel to set Skip / Low / Normal / High. Rename an individual file inside a torrent (double-click or the file menu), separate from renaming the torrent. Remove a tracker from a torrent (the ✕ on a tracker row); adding was already there. Smart Paste on Ctrl+V — paste a magnet, a 40-char info-hash, or a .torrent URL straight from the clipboard and it's added immediately (text fields still paste text normally). Covers & titles Anime fansub naming ([Group] Title - NN) now resolves to the right show. Audio channel layouts in titles (DDP5.1, 7.1, …) are stripped so they don't pollute cover matching. Under the hood The legacy QWidget interface is gone. QML had been the only UI since 3.0.0 (reachable old code lived behind a hidden --legacy flag); with parity confirmed, the entire QWidget layer — main window, every dialog, the theme manager — was removed (~13,400 lines). The four restored actions above were features that backend already supported but the QML port had never wired. macOS: the WebUI password hash moved out of the keychain into app settings, so launching the app no longer pops a login-keychain password prompt on unsigned builds. The actual password still lives in the keychain. Cleanup: ~400 orphaned translation strings and a batch of dead code removed; internal duplication collapsed; an ARCHITECTURE.md added for contributors. Unit / security / memory tests and the ASan/UBSan/TSan sanitizers stay green.

      How about a global switch to turn the awful things off instead of a registry hack? Then everyone wins.
