Microsoft Edge web browser recently just got an upgrade to version 100. This comes two weeks after Edge Insiders received version 100 in the beta channel. Given the large version number, there are just five changes in this version, according to Microsoft.

Changes to the user-agent string, improvements to Microsoft 365 application protocols, hardware-enforced stack protection, and PDFs are among the five changes in version 100. All of these have been put through their paces with Edge Insiders over the last few months.

Here’s the full changelog:

• The three-digit version number in the User-agent string. Microsoft Edge will now send a three-digit version number, such as Edg/100 in the User-Agent header.
• Streamlining Microsoft 365 Application Protocol Activations. Microsoft 365 Application Protocol Activations on trusted Microsoft cloud storage services will now launch certain Microsoft 365 applications directly, including SharePoint subdomains and Microsoft OneDrive URLs.
• Hardware-enforced Stack Protection. Microsoft Edge will continue supporting more fine-grained protection by combating memory corruption vulnerabilities and by protecting indirect calls.
• Open Digitally Signed PDF files. Digital signatures are used extensively to validate the authenticity of a document and changes made in a document. You can use the PDFSecureMode policy to enable digital signature validation for PDF files, directly from the browser, without the need for any add-ins.
• Preview PDF files in Microsoft Outlook and File Explorer. Users can view a PDF file in a lightweight and rich read-only preview. This feature is available for Outlook Desktop PDF attachments or for local PDF files using File Explorer.

To all those who keep track of policy changes, there are several new ones in this version, as well as several that have been deprecated. These can be found in Microsoft’s changelog. The Edge should automatically download this update, but if it doesn’t, go to the Help and feedback menu in Edge, select About Microsoft Edge, and restart the browser when required.

Since the launch of the new Chromium-based Microsoft Edge over two years ago, the browser has progressively risen to the top. According to the most recent Statcounter report from March, Edge is the world’s second most used browser, with a 4.05% market share. Chrome comes in second with 64.53%.
