Pale Moon 15.2 is an update to address a number of security issues, addresses current performance, and redesigns the way secure sites are displayed, among other things.

Changes in this version:
The identity panel has been redesigned, both for potential abuse of the new logic implemented in version 15.1 and because people clearly indicated that they would want to see the padlock permanently present on secure sites, while still seeing the favicon.
The padlock has been made a separate indicator now, and will be shown on SSL (HTTPS) sites, to the right of the domain name (domain verified) or company name (extended verification) information in the identity panel, by default. A few options have been implemented for style, including "old school" display of the padlock in the status bar of the browser. For more information about how to change the location of the padlock, see the Pale Moon Tweak Guide (PMTG)
The padlock will indicate whether a site is secure (gold padlock), has extended verification (green padlock) or if there is a problem with security (low-grade encryption or mixed content). A click on the padlock will open a details window with security information.
The address bar now has either a blue or green slight shading (border) for SSL sites, further clarifying that you are on a secure site. This can be disabled if desired via about:config. See the Pale Moon Tweak Guide (PMTG) for instructions.
Address bar auto-completion is now on by default.
After re-evaluating the auto-fill algorithm, autocompletion of domains on the address bar has now been enabled by default. This may interfere with searching from the address bar for some people, but:
- You have a search box on the right, you can use that, which has the intended functionality
- You can press space or another key to remove the auto-filled portion before pressing enter
- You can disable autocompletion from the Pale Moon status bar options:
Status -> tab Address Bar -> Firefox compatibility
Partial Japanese implementation for status bar options (preferences only)
Important performance regression fix.
Both JavaScript and the layout engine should now have the speed and stability that is to be expected from an optimized browser. In previous, recent versions, some concessions had to be made in terms of performance to provide proper stability for Pale Moon. Working around bugs in the Microsoft compiler is tricky, but with some fine-tuning, Pale Moon now gets the benefits of maximum performance again like in the past.
Fix for the "tabs on top" menu entry not showing when tabs are already set on top, making it very difficult to switch them back to bottom.
Firefox 15 removed the context menu entry for "tabs on top" when tabs were set on top, making it impossible without going into about:config to set them to being on the bottom once you had changed it. This is considered a serious UI bug for Pale Moon, because it destroys intuitiveness for this option (you cannot use the same method you used to set them on top (context menu in the UI), to switch them back to being on bottom (having to manually change a parameter in about:config)). To make matters worse, this problem would only occur after a browser restart, meaning the UI would change simply because you closed and restarted the browser, removing this menu option.
Crash fix: Fix for a browser crash with certain types of invalid gradients. (bug #792903)
Security fix: Prevent private browsing data leakage through popup windows (bug #795015)
Security fix: Detect IC purging (bug #794025)
Security fix: Prevent mRules from dying in DoInsertHTMLWithContext (bug #788950)
Security fix: Drain the parent frame's overflow list before insert/append (bug #765621)

- Under the hood changes and improvements to the way memory is handled by the Javascript engine.
- WebGL has been changed to use ANGLE by default instead of using native OpenGL to give better performance on a number of systems that would otherwise suffer from high CPU usage and lower frame rates.
- Change in compiler: from this point on, Visual Studio 2010 will be used for all "next gen" builds.
- Build environment changed to cater to the ever-growing XUL dll size without having to compromize on what modules to optimize. (Prevent running into the 3GB address space limit)
- DNS prefetching disabled by default to prevent router hangups
- Changes to timings for UI script execution and content script execution to prevent unnecessary dialog popups about unresponsive scripts.
- Some image decoding tweaks.
- Eye candy: animated preferences dialog (resize when switching category).

A major update building on the Firefox 8.0 code base, with improvements that were planned for the (unreleased) version 7.0.2.
This version sees the following improvements in addition to those inherent to Firefox 8:
- Improved cache handling: this will make the browser handle system resources more efficiently on most systems.
- Improved networking: communication with web servers should be noticeably faster and smoother
- Fix for a rare image decoding bug (garbage, possible crashes)
It should be noted that the shift in focus of development has been towards the back-end of the browser (background resource handling and background networking), considering the rendering and scripting speed is not the bottleneck for current versions of the browser. Inherently, this may result in less of a clear difference in benchmark scores when comparing to its vulpine sibling or previous versions of Pale Moon because of rebalancing of code priority when building. Maximum benchmark scores are nice, of course, but the main goal of Pale Moon remains to be as efficient as possible when taken as a whole, including those parts that aren't measured in limited benchmark tests

The new version of Pale Moon is based on based on Firefox 6.0 and has added ak, ast, br, bs, en-ZA, gd, lg, mai, nso, and son language packs, Add-ons will no longer automatically update by default the moment they are checked and found to have a newer release, giving the user the choice to accept or reject the update, read release notes,update of the status bar add-on to v2.2, fixing compatibility issues and extending some configurability, Link right-click menu has "Open in new tab" on top now,performance issues fixed on some systems, instability problems fixed on some systems,updated artwork for the new about box, cosmetic changes and Zulu language added for the language packs

A number of fixes and a cosmetic update:
Performance fix: Javascript performance improved.
Crash fix: Prevent crashes in optimized builds of JS due to 20110410-CCBug.
Updater fix: Internal updater should function again from this version onward.
Add-ons window shows the proper add-ons page when loading it.
Shell integration fixed for Vista and 7: The browser should no longer complain that it's not the default program when it, in fact, is. See bug 20110408-SHBug.
Main Pale Moon program icon updated with a higher-res version of the logo image.
