  "message": "Revert \"update_engine: Deprecate major version 1\"\n\nThis partially reverts commit 55c75417e22d5026971276997924a345d9973bbc.\n\nIt turns out that we forgot a scenario when we deprecated major version\n1. We use update_engine in lab tests (specifically\nautoupdate_EndToEndTests on stable channel) to update a DUT to an\nold (very old) versions using actual update payloads so we can test that\nthey can get updated to newer versions. However, deprecating major\nversion 1 in the update_engine caused trouble because we no longer can\nupdate from a newer version to a version before M72 (to prepare the\ndevice for update test). We need to put this feature back until we find\na better solution for it.\n\nOn this CL, we only support major version 1 in the client and only for\ntest (non-official) images. We don\u0027t even bother adding paygen support\nfor it.\n\nThis CL should be reverted once we figured out what to do with\nprovisioning the autoupdate end to end tests.\n\nBUG\u003dchromium:1043428\nTEST\u003dFEATURES\u003dtest emerge-reef update_engine\nTEST\u003dcros deployed it, then cros flash using an m71 payload, it succeeded.\n\nChange-Id: I1fecbe3ae845b2e419f0999adc53e4732b1f7696\nReviewed-on: https://chromium-review.googlesource.com/c/aosp/platform/system/update_engine/+/2013884\nReviewed-by: Tianjie Xu \u003cxunchang@google.com\u003e\nReviewed-by: Sen Jiang \u003csenj@chromium.org\u003e\nTested-by: Amin Hassani \u003cahassani@chromium.org\u003e\nCommit-Queue: Amin Hassani \u003cahassani@chromium.org\u003e\n(cherry picked from commit fac20229289cf4d4373fffe83037d44b780eabd0)\nReviewed-on: https://chromium-review.googlesource.com/c/aosp/platform/system/update_engine/+/2016088\nReviewed-by: Amin Hassani \u003cahassani@chromium.org\u003e\n",
