What you need to know

  • Microsoft delayed this week's Microsoft Edge Dev build not long after announcing it.
  • This update would have brought Collections to the Dev channel, along with Windows 10's native Share functionality.
  • There's also the usual lengthy list of performance improvements and fixes.

Updated August 30, 2019: After announcing the build yesterday, Microsoft has provided an update saying that it has decided to delay the build after running into issues rolling it out. "Since it's already Thursday, it's very likely we aren't going to have an update this week," the company added in its updated release notes. The original story follows.

This week, Microsoft has moved the new Collections feature to the Dev channel, added Windows 10's native Share functionality, and issued a lengthy list of bug fixes and performance improvements.

Collections first rolled out to the Canary channel last week. The feature lets you name and build out collections of everything from web links to photos and text snippets.
