We're halfway through another week of 2020, and that means it's time for Microsoft to release a new build of Windows 10 for Insiders enrolled in the Dev channel, formerly known as the Fast ring. This week's build is 20236, and as far as new features go, there's

Of course, that's not all that's coming with this build, and we also get the usual array of improvements, fixes, and known issues you'll need to look out for. Starting with the list of improvements, there's only a single change and it's related to accessibility in PDFs:

• To improve accessibility of PDFs for Narrator and other screen reader users, in the cases where Unicode is not provided by the printing application, we’re updating our Microsoft Print to PDF option to make an attempt to convert the provided font glyphs to Unicode.

Finally, there are some known issues with this release, which you may want to look at before installing the new build. There's still a few, despite all the fixes in this build:

• We’re working on an issue where new applications will fail to install with a Windows Installer service error on x86 systems. Windows x64 isn’t affected.
• We’re working on an issue where when attempting to perform a Reset this PC using the Keep My Files option will fail with the error, “There was a problem resetting your PC. No changes were made”.
• We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.
• Live previews for pinned sites aren’t enabled for all Insiders yet, so you may see a grey window when hovering over the thumbnail in the taskbar. We’re continuing to work on polishing this experience.
• We’re working on enabling the new taskbar experience for existing pinned sites. In the meantime, you can unpin the site from the taskbar, remove it from the edge://apps page, and then re-pin the site.
• We’re working on a fix for an issue causing some devices experiencing a KMODE_EXCEPTION bugcheck when using certain virtualization technologies.
• We are working on a fix for an issue where selecting an IME candidate or hardware keyboard text prediction candidate may insert the candidate adjacent to the one selected.
• We’re investigating an issue reported by some Insiders wherein the taskbar is obscuring the Power button in the Start menu. If this is happening on your PC, you may need to use the Windows key plus X menu to shutdown for the time being.
• We’re investigating reports from some Insiders that they’re experiencing APC_INDEX_MISMATCH bugchecks.

As usual, it's worth keeping in mind that any new features in these builds may not make their way to a public release of Windows 10, or at least not the next one. Plus, these builds are in a different development channel from the upcoming October 2020 Update, which is pretty much finalized and you can read about it here.
