1. effective "Differential Upgrade" patch algorithm with high compression rate 2. effective recovery algorithm support recovery firmware in blocks which has low memory consumption and wear-leveling strategies, especially suitable for embeded devices with low RAM. 3. add sample ota bootloader project, see: board\TencentOS_tiny_EVB_MX_Plus\KEIL\ota\ota_bootloader_recovery 4. add sample application project for download firmware through http, see: board\TencentOS_tiny_EVB_MX_Plus\KEIL\ota\ota_application_download_through_http 5. add sample application project for download firmware through qcloud explorer console, see: board\TencentOS_tiny_EVB_MX_Plus\KEIL\ota\ota_application_download_through_qcloud_iot_explorer 6. an OTA markdown document is pending
