For users who have difficultly applying flags through the chrome://flags interface, the core "classic" switches can be made part of the Supermium shortcut in the installer, or be used through a script in the Supermium folder named "Supermium (Classic)". Similar options are available for ungoogled-supermium mode, to help ensure that the user does not compromise their privacy by ever opening the browser in "googled" mode.

This is a modified version of Supermium 122 R2 chrome.dll for debugging purposes. Now revised.

The following changes are made in this release:
-File dialog filters fixed on Windows XP
-Crashpad process should now work on Windows XP
-Field trials disabled on Windows XP due to stability issues
-Fixed Noto Emoji font for Windows XP
-Supermium should now start on some Windows XP systems previously unable to start it
-Browser should show up in list of default browsers on Windows 8.1 through Windows 10 1809 - unspecified, undocumented changes to browser registration are complicating matters on Windows 10 20xx and above
-Attempt at fixing remaining Windows 7 freezes

Here are the following changes in this release:

-Renderer stabilization on Windows 7

-A new XP-compatible installer. The installer can optionally create shortcuts and install the Noto Emoji font for emojis to appear on
older operating systems

-Change in base of chrome.dll on 32 bit Windows to ensure reduced memory usage

-Printing should now be functional on Windows XP

-Stabilization of tasks such as 8K video viewing and large downloads from MEGA in 64 bit Supermium

-Improvements in GDI rendering on web pages

-Native tooltips are restored (standard on Windows 7 and below, optional on Windows 8 and above, using --legacy-tooltips-win). This will eliminate issues with the tooltips being hidden behind the window

-Several new flags from ungoogled-chromium:

--max-connections-per-host

--show-avatar-button

--popups-to-tabs

--disable-search-engine-collection

--custom-ntp is updated to feature the bookmark bar by default. The flag --bookmark-bar-ntp can toggle this functionality if the user wishes for it to be disabled.

A new flag to disable the PWA install icon prompt which appears in the address bar on certain web pages:

--disable-pwa-install-prompt

This is a special release of Supermium 121 for debugging purposes only. It contains debugging symbols for important Supermium components.

All regular releases of Supermium going forward will feature distribution of debugging symbols.

This updated version of Supermium Version 121.0.6167.81 includes various fixes that mostly target Windows 7, as well as some backported Chromium features.
-Compositor-induced instability should be eliminated
-Printing should be possible again on Windows 7
-Various UI bugs are fixed. For example, the current tab should no longer be transparent with the Transparent Tabs option. The default tabs are now the current Chromium tabs.
-Improved icon that should no longer display red squares. The logo design itself remains unchanged at this time.
-#hide-sidepanel-button is fixed
-Disabled #power-bookmarks-side-panel is fixed

The hotfix was revised to restore D3D11 support.

-Windows XP and Windows Server 2003 support restored, including x64. Self-extract or use the portable distribution available
through the Supermium Plus Package on https://www.patreon.com/win32 as the regular installer does not work on XP/2003.
A new installer will be developed to resolve the shortcomings of the regular installer.
There should be few caveats compared to Supermium on other platforms, with exception of hardware
acceleration and some issues with printing of web pages.

-New branding and new interface elements, specifically with regards to tabs. Trapezoidal full-sized
tabs are the default, but the following options in chrome://flags can be used to customize the tabs:
#custom-tab-shapes - if disabled, reverts the tabs to the standard Chrome look.
#override-tab-outline-default - black outline enabled by default with trapezoidal tabs, but not rounded tabs.
#override-new-tab-button-shape-default - toggles between rounded new tab button and trapezoidal new tab button.
#compact-ui - reduces the padding of the address bar and the tabs.
#transparent-tabs - introduces some level of transparency to tabs (best with Aero Glass enabled)

-Many new flags from ungoogled-chromium. There are too many to list, but they include:
#tab-hover-cards - disable tab hover cards
#custom-ntp - set a custom new-tab page
#disable-sharing-hub
#clear-data-on-exit

Other flags will be shown in chrome://flags with "ungoogled-chromium" attribution in their descriptions.

-In particular, the flags #disable-encryption and #disable-machine-id now make Supermium user data portable
if enabled. The "portable" distribution will have a launch script with these flags enabled as well as a data
directory in the same directory as the executable.
-The option to restore the download shelf has been restored with the use of flag #download-bubble. to disable the download bubble.
-Flag #power-bookmarks-side-panel has been restored.
-Click-to-Call feature restored.
-GDI offsets in UI fixed. GDI crashes resolved.
-Rendering issues with tooltips and other UI elements should be resolved.

Please note that 2 CPU threads and at least 768 MB of RAM is recommended. We will make attempts to improve
performance on single-threaded systems for future releases.

-Moved to Chromium's stable branch. It is based off Chromium 119.0.6045.192, but incorporates some extra patches, such as patches against CVE-2023-6345.
-Windows Vista is now supported, at a level of SP2 (extended kernel not required anymore). Platform Update is optional. 64 bit browser recommended (especially for extended kernel users).
-GDI font rendering is now available, with the command line switch --disable-direct-write or the persistent flag #force-gdi.
-Protocol handling is fixed upon discovery of protocol handler string length limitation bug in Windows. On Windows 8.1 and above, this also fixes the issue of Supermium being excluded from the list of potential default browsers.
-Screenshot feature in Sharing Hub (in address bar) is restored.
-Appearence of PWAs is corrected to match the themes native to Windows NT 6.x systems.
-Safe Browsing Download crash bug is fixed.
-A persistent flag is now available to ensure that the system handles titlebar drawing on Windows 10: #disable-windows-10-custom-titlebar. This can be used in conjunction with AeroGlass for Win8.1+ or similar products.
-Localization issues are resolved and stray English-language strings should no longer appear.

NOTE: the 32 bit package was revised on 2023-12-04 to improve stability on 32 bit Vista.

The zipped browser folders are recommended if the browser is not to be placed in the user data folder.

An earlier release of 118.0.5991.0 was withdrawn due to a critical bug specific to Windows 7.

Changes:

-CVE-2023-4863 patched

-Updated to M118

-Secure DNS fixed on Windows Vista/7

-Google Sync and account integration introduced

This release was expedited due to the critical security vulnerability mentioned above.

The args,gn used to make this release is included here.

-x64 memory issues are corrected; memory usage should generally be lower than other Windows 7-compatible Chromium browsers above version 110
-x86 sandbox is fixed; x86 download issues are fixed
-Theming inconsistencies are corrected; Aero Glass now appears with custom themes while custom themes are now workable with the "XP-style" theme
-Widevine CDM support (not bundled with browser binaries but downloaded when needed) is now available; works with sites such as Bell Fibe TV but may not work with sites like Netflix, which seem to block non-oligopolic browsers (so nothing outside of the Firefox/Chrome/Safari/Edge grouping seems to work - UA-CH spoofer will be introduced in future to deal with these unfair blocks, and possibly other measures if necessary)
-User agent client hints are updated to return values for Windows 2000 and up; the values for 2000-Vista are outside of the scope of official documentation because it did not account for those versions of Windows
