Back on Friday Microsoft released a configuration update for Windows 10 mobile fast ring insiders mainly designed to prepare devices for new cumulative updates.
With Microsoft still on target to start pushing out Windows 10 Mobile to older Lumia devices early this year they are working hard to refine and polish the OS now.
Today Gabe has pushed the red button to release mobile cumulative update build 10586.71 to Insiders in the fast ring and it includes a several important bug fixes and performance optimisations.
Gabe also wrote in his blog post that Insiders that already have the configuration update released on Friday will get a slightly better experience when upgrading to this build however those who didn’t get download or their phone didn’t automatically download and upgrade will have the update downloaded alongside this build.
