Firefox and Chrome use a rapid-release, schedule-drive approach, often described with an analogy to trains, where features ready to release board the current "train," and those that are not finished simply wait for the next scheduled release to leave the station. Microsoft already uses that method for its security fixes, with certain exceptions — widely-exploited vulnerabilities are sometimes patched "out-of-cycle" — and the new Windows process sounds similar.
LeBlanc characterized the change as a way to "respond more quickly to customer and partner feedback" and to "refine and improve Windows 8.1 in a more nimble way." But analysts thought there was more to the story.
With Threshold/Windows 9 approaching, Redmond is putting Windows 8 on a back burner, reducing the number and significance of improvements and new feature introductions to the latter.
"Absolutely," said Wes Miller, an analyst with Directions on Microsoft, when asked whether Microsoft had shifted resources to the new Windows at the expense of the older edition. "You can see that in the things that aren't releasing for Windows 8.1."
By that, Miller meant the features — notably a revamped Start menu that Microsoft showed off earlier this year — once thought to reach Windows 8.1, but that have now been postponed to Threshold. Microsoft is saving those features for the next Windows as a way to differentiate the new from the old, and put the Windows 8 flop in its rearview mirror.
Not naming further Windows 8.1 updates could be interpreted as another way Microsoft is cutting Windows 8 loose by pushing the widely-panned OS into the PR and news background.
Miller and others also tried to read the tea leaves in LeBlanc's blog, and speculated that the feature dribble tactic may be the new black, and that major upgrades, both in the quantity of new content and how they're distributed, may also change as a result.
If extended throughout Windows' development and release cadence, a constant, train-style process would by its nature downplay major editions even more than has been the case since Windows 8's launch. That, in turn, would bolster the rumors that Microsoft will either give away Threshold to current Windows 8, perhaps even Windows 7 users, or heavily discount upgrades if, as many anticipate, it will be less an overhaul and more a mid-sized tweak that continues the backpedaling from Windows 8's touch-first focus.
But the experts disagreed on what Microsoft's frequent-update message means. Does it mean Microsoft has abandoned the controversial concept of mandating designated updates if customers want to keep getting patches, as it did when it set Windows 8.1 Update 1 as a "new servicing baseline," then gave enterprises just four months to deploy Update 1?
