Jul/02/2021 ver 1.7.5
 - Supports TLS 1.1 / 1.2  
   Changed to NET Framework 4.6.0 (Supports TLS 1.1 / TLS 1.2)

Oct/31/2025 ver 2.0.1
 - Authentication changed to certificate-based authentication.
   Previous: Microsoft Graph (Authorization Code + PKCE flow), SharePoint (Azure Access Control Services (ACS))
   Now: Client Credentials flow using certificate authentication (certificate-based).
   Note: Client Secret cannot be used with SharePoint CSOM, therefore authentication was switched to certificate.
 - Upgraded to .NET Framework 4.8.1 (upgraded from .NET Framework 4.6.0).
   Note: .NET Framework 4.8.1 relies on the OS SChannel for TLS; TLS 1.3 availability depends on the Windows version and updates (e.g. Windows 11 / Windows Server 2022 or later with relevant updates).

Jul/17/2026 ver 2.0.2
  - Improved processing speed and fixed abnormal termination caused by timeouts.
    - Optimized how the access token is acquired.
      Previously an access token was acquired for every single file, which could cause
      slow processing and abnormal termination due to timeouts ("A task was canceled")
      on sites containing a large number of files. The token is now cached and reused
      per site, which resolves this issue.
    - Explicitly set a timeout (10 minutes each) for the HTTP communication used when
      downloading files. This prevents large file downloads from being interrupted by
      the default timeout (100 seconds).
    - Added automatic retry with wait when SharePoint Online throttling (HTTP 429/503)
      or a temporary communication error occurs. When the server specifies a wait time
      (Retry-After), the application follows that instruction. Files that do not recover
      after retrying are skipped individually, their file names are recorded in the log,
      and processing continues (a single file failure no longer stops the whole process).
  - Enhanced logging.
    - When the process terminates abnormally due to an error, detailed information for
      troubleshooting (exception type, message, HTTP status, inner exception, and stack
      trace) is now written to the execution log (EOBLogs\EOBLog_yyyymmdd_hhmmss.txt).
      This detailed error log is always output.
    - Added a feature to periodically output performance information such as the number
      of processed items and elapsed time. (See "Performance Log" below.)
 
    [Performance Log (optional)]
    - Disabled by default, because it increases the amount of log output.
    - When enabled, the following information is written to the log
      (EOBLogs\EOBLog_yyyymmdd_hhmmss.txt):
        - Processing progress at regular intervals (about every 60 seconds)
          e.g. [PERF] Progress: Items=1,234, Files=567, Errors=0, Elapsed=00:12:34
               Items   ... Number of processed database (list) items
               Files   ... Number of downloaded files
               Errors  ... Number of errors
               Elapsed ... Elapsed time
        - Download size and elapsed time for each file
          e.g. [PERF] Download: 1,048,576 bytes, 320 ms : (destination file path)
    - How to enable:
      Add the following tag to the configuration file (EOBConfig.xml / the XML for batch):
          <PerfLog>true</PerfLog>
      To disable it, specify false or remove the tag (disabled by default).
      * You can also toggle it with the "Output performance log (EOBLog.txt)" checkbox
        on the main screen. The value is saved to EOBConfig.xml when the backup settings
        are saved.
      * You can also choose the parallel degree on the main screen (1 to 4). The default
        value is 2.

    [Log output location]
    - Log files are written to the EOBLogs folder in the same folder as EOB.exe.
      - Execution log / progress / error details ... EOBLogs\EOBLog_yyyymmdd_hhmmss.txt
      - Debug details (only when debug mode is enabled) ... EOBLogs\EOBDebug_yyyymmdd_hhmmss.txt
    - Progress information and error messages are also shown on the screen (or the console
      window in batch mode).
    - Detailed information for errors is not shown on the screen and is written only to
      EOBLogs\EOBLog_yyyymmdd_hhmmss.txt.
    - If you enable the "Delete old logs" checkbox on the main screen, log files older than
      30 days in the EOBLogs folder (EOBLog_*.txt / EOBDebug_*.txt) are automatically deleted
      (disabled by default).
      The retention period can be set from 0 to 9999 days. 0 means unlimited (no deletion).

    [Performance verification result (internal test)]
    - Test date: 2026/07/27
    - Test condition: same target scope (Items=3,495 / Files=3,449), Errors=0
    - Measured elapsed time:
      - Parallel degree 1: 00:05:06
      - Parallel degree 2: 00:02:46
      - Parallel degree 4: 00:02:39
    - Comparison:
      - Parallel degree 4 is about 48.0% faster than parallel degree 1.
      - Parallel degree 4 is about 4.2% faster than parallel degree 2.
