W10M is shipped to OEMs (RTM) | November 16th 2015 | Build 10586 is what will be shipping on 950/XL/550 devices. source WCentral was told that 10586 was shipped to carriers for testing sometime during the first week of November. source According to Microsoft, W10M 's official release date was November 16th 2015. 10586 will not be the build MS uses to update the first wave of WP8.1 devices OTA, as it didn't prove stable enough for widespread distribution to WP8.1 devices. |
W10M final distributed OTA via carriers for your current WP8.1 device | TBA | Devices will be updated in batches. MS defined those batches on their own website, which has since been removed. Luckily, a copy found it's way into our forums and is available here: post When the first batch of WP8.1 devices will receive W10M updates is yet unclear. Until recently we've had nothing more to go on than an unnamed MS insider stating to Marry J. Foley: "early 2016". source In late January, the french telecom company Bouygues tweeted that the first batch of WP8.1 devices would not receive the W10M update before the end of February. source All of the above are just rumors and not commitments made by MS. So far there is no mention of updates beyond the first batch, so we know even less about those devices. Whether your phone is in the first batch or not, don't expect all WP8.1 devices to be updated on the same day. As always, updating all WP8.1 devices will occur over a period of months, and the specific update date for any particular device will vary by model and region. Additional information that may be of interest to you is available here. Some devices will not be updated at all. See post #2 for more. |
