This month’s Update Tuesday rollout brought us quite a lot of improvements, including the brand new August Update that’s specifically aimed at devices running Windows 8.1 Update or Windows RT 8.1 Update.

Internet Explorer 11 however also received its own round of improvements and, according to a blog post published by Microsoft, the browser should now be even faster than before.

Specifically, this new update includes four feature improvements for developers, based on the feedback that the company received from users. The F12 developer tools received tweaks in several areas, including the user interface, console, DOM explorer, debugger, emulation tool, UI responsiveness and memory profiling tools.

At the same time, the company also implemented a series of changes under the hood to make the WebGL renderer work faster, which led to an improvement of the Khronos WebGL Conformance Test 1.0.3 score from 89.9% to 96.8%.

“The WebGL renderer has also been updated with support for ANGLE_instanced_arrays, OES_element_index_uint and WEBGL_debug_renderer_info extensions, the failIfMajorPerformanceCaveat context creation attribute, 16-bit textures, more GLSL conformance, and line loop and triangle fan primitives,” Microsoft explained.

“Additionally, more Windows 7 systems will now render WebGL in hardware mode if your drivers are up-to-date.”

Security-wise, Internet Explorer 11 received one of the two critical security updates supposed to fix one publicly disclosed vulnerability and no less than 25 privately reported flaws in Microsoft’s in-house browser, with the company confirming that, with the help of a compromised website, a hacker was capable of taking control of an unpatched system.

“The most severe of these vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights,” Microsoft said.

Last but not least, Internet Explorer 11 also got patched with the latest Adobe Flash Player version in order to make sure that no security glitches exist in this software that could be used to access user data and compromise a system.

Since we’re talking about Internet Explorer 11 improvements, all these patches are being delivered to devices running the browser via Windows Update, so users do not need to move a single finger to receive them. Instead, some updates, especially the KB2976627 security bulletin, might require a reboot, so make sure that you save your work before launching installation.
