UpdraftPlus WordPress Backup Plugin - Version 1.4.27

Version Description

  • 02/23/2013 =
  • Now remembers what cloud service you used for historical backups, if you later switch
  • Now performs user downloads from the settings page asynchronously, meaning that enormous backups can be fetched this way
  • Fixed bug which forced GoogleDrive users to re-authenticate unnecessarily
  • Fixed apparent race condition that broke some backups
  • Include disk free space warning
  • More intelligent scheduling of resumptions, leading to faster completion on hosts with low max_execution_time values
  • Polls and updates in-page backup history status (no refresh required)
