GPT-Load v2.0.0-beta.10

GPT-Load 2.x is a rewrite and is not compatible with 1.x data — do not open a 1.x database with this release.
Start 2.x from an empty database and a new encryption.key; verify, then cut traffic over manually.
See the README for deployment, backup, and 1.x cutover details.

GPT-Load 2.x 是全新重写版本，与 1.x 数据不兼容 — 请勿使用本版本打开 1.x 数据库。
请以全新数据库和新的 encryption.key 部署 2.x，验证无误后再手动切换流量。
