I was checking my Cr-48, which my mother uses regularly, and which is in the Beta channel, and saw that it was on version 56.0.2924.87, which was announced on the Chrome Releases blog in early February. The beta channel for Chromebooks is now up to version 58, and the Stable channel is up to version 57. I also saw that that the version 56.0.2924.110 was announced for the Stable channel in late February, while the Beta channel had moved onto version 57 after the version on my Cr-48. I switched my Cr-48 to the Stable channel, and it updated to version 56.0.2924.110 (and switching to the Stable channel also erased all user data, so I had to set it up again as if it were a new Chromebook.)
Has Google in fact stopped updating the Cr-48 now, and are these the latest versions available in the Stable and Beta channels, and does anyone know what version is in the Dev channel?
