Below of is a summary of the features and improvements added to IBrowse 2.5 since IBrowse 2.4:

New Features

OS4 Native Version Added (OS4.1 Final Edition Required)
In addition to the OS3 68k version of IBrowse, an OS4 PPC native version will also be available. This is not a simple port, but we have taken great care to ensure it fully utilises of all the relevant new features avaiable in OS4 and as such requires a minimum of OS4.1 Final Edition. Uses the new graphics.library RTG system, dropping CyberGraphX support completely. Other features include faster image rendering using hardware compositing, anti-aliased text rendering and proper daylight saving time handling.

OpenSSL 3.0 / AmiSSL v5 Support
OpenSSL Support for the latest AmiSSL release has been added to IBrowse 2.5, allowing the use of the most up to date SSL implementation (OpenSSL 3.0) available for AmigaOS. Whilst this adds support for TLSv1.0-TLSv1.3 and the latest ciphers, we have also dropped SSLv2 and SSLv3 support completely (including MiamiSSL). SNI (Server Name Information) support has be added for HTTPS. Certificate verification has been added, which prompts the user when necessary, to protect against "Man in the Middle" vulnerabilities. OS4 users will be able to benefit from the improved speed of the PPC native SSL implementation, including specific PPC speed optimisations and AltiVec acceleration, and other AmigaOS compatible systems will be able to use the 68k implementation. The AmiSSL Open Source Team are still looking for developers to handle the MorphOS and AROS builds of AmiSSL - unfortunately, no volunteers have come forward to help with the project.

SSL Session Caching
IBrowse now implements a SSL session cache for all HTTPS connections, supporting all the differing session/ticket methods used from TLSv1.0 to TLSv1.3. This allows the slow initial handshaking to be bypassed on subsequent connections to the same host, thus increasing performance noticably on OS3, and even on OS4 too. Most websites support this feature universally.

Persistent Connections
This is an older HTTP feature that was never implemented in IBrowse until now, partly because IBrowse has always relied on opening multiple connections to websites, which didn't really make this feature worthwhile. However, it can be useful for HTTPS connections as it allows them to be left open and reused, without having spend CPU time renegotiating the SSL connection at all. Not all websites support persistent connections and, some of those that do, do not keep connections open long enough (e.g. 1 second) to make a difference.

Gemini Client
Added support for the Gemini protocol and gemini:// URLs.

MUI 4.0 and 5.0 Support
IBrowse 2.5 will still work with MUI 3.8 (although, we recommend 3.9 as a minimum) and we have added support for new features in 4.0 and 5.0. This includes using MUI's context sensitive pointers instead of our own which were introduced in IBrowse 2.4, support for various built-in MUI menus and other new GUI additions.

Alpha Channel Support on >= 15-bit Displays (OS4 / MorphOS)
Alpha channels in images are now fully supported and displayed properly on non-colourmapped displays.

4Gb+ File/Downloads (OS4)
The OS4 version of IBrowse 2.5 is able to properly support handling and downloading of files bigger than 2Gb, with all status information now capable of displaying sizes larger than 4Gb.

Customisable Spoofing Strings
Spoofing HTTP and Javascript User-Agent and related JavaScript properties may now be fully customised, allowing existing strings to be duplicated and edited, and new strings added. The "Spoof As" menu can also be fully customised to show the entries you want there. These settings can of course also be applied in the URL Prefs also, as in previous releases.

OpenSearch Support
IBrowse 2.5 now supports the OpenSearch standard allowing search engines to automatically be added to the search bar. This is possible via JavaScript or OpenSearch autodiscovery. This is in addition to the older Sherlock/Mycroft search engine support available in IBrowse 2.4.

Rewritten Features

TextEditField Text Editor
IBrowse's TextEditField object has had an overhaul, fixing various issues and adding new features. Rendering is done in a more MUI4/5 compatible manner allowing these objects to inherit your MUI settings. Your mousewheel can now be used for scrolling and various MUI defined keyboard shortcuts are now honoured.

Disk Cache Clean
This is really a new feature, albeit not an exciting one, as the disk cache clean menu item never used to do anything. Now it actually will erase all unused items, as it can happen that untracked files can get lost there and never deleted, due to bugs or if IBrowse is not shutdown correctly. There have also been a few fixes to the disk cache, during day to day operation, to prevent old files being left untracked there.

Improved Features

HTTP Engine
Various fixes and improvements, making IBrowse compatible with more servers. Now also supports Brotli compression, the "Do Not Track" and "Upgrade-Insecure-Requests" headers, chunked transfer encoding and faster password protected sessions.

HTML Engine
The existing HTML4 engine has been enhanced, with improved support for more tags and attributes, as well as being compatible with more sites. Redraw speeds of background images containing transparency has been greatly improved.

JavaScript Engine
JavaScript engine has been improved yet further, with various improvements, bug fixes and crash fixes. Improved parsing speed of large inline JavaScript section in HTML. Fixed various issues that could occur, and increased performance, when JavaScript is disabled.

Internal Image Decoders
Warp Datatypes All the internal image decoders have been improved, with various fixes, alpha channel handling, and speed optimisations. The JPEG and PNG decoders now fully utilise the decoding improvements and optimisations from the current Warp Datatypes, which also includes AltiVec acceleration in the JPEG decoder.

Cookie Support
The hardcoded 2000 global cookies, with a 200 per domain, limits introduced in IBrowse 2.4 are now adjustable in the preferences. An AmigaDOS pattern can also be used to automatically block certain cookies from being accepted. For the Cookie Manager window itself, real-time updating no longer slows everything down while browsing and columns are now click sortable. Third-party cookies can now be blocked globally and/or via the URL prefs settings.

Gopher Client
The Gopher client has been improved, adding support for 'i' and 'h' lines, and fixed invalid image shown for CSO lines.

Password Manager
The password manager can now also store FTP login information. Issues with setting a master password have been fixed along with a crash bug.

Various GUI Elements
The background of browser tabs now uses your MUI "Groups / Tab groups / Container" setting. As a whole, IBrowse's GUI is more compatible with MUI 4.0 and 5.0 than previous versions of IBrowse.

Memory Management
Further improvements to the memory management and usage, plus more memory leaks plugged.

Bug Fixes
It perhaps goes without saying that many bugs, some minor, some crash inducing, have been fixed for IBrowse 2.5, making it the most stable version ever.
