    With the licensing change, will it apply to older licenses or just new ones since Release 80?

    Bvckup 2 v81.3.1 Released (June 5, 2020)
    Website / Download: https://bvckup2.com/update
    Release Notes
    Release 81.3

    ⦁ Reworked retrying logic to act on errors that occur when processing item attributes. That is, the program will now retry folder creation, file/folder move and file copying steps if they fail with a transient error when cloning item's meta data (attributes, timestamps, security info, etc.)

    ⦁ Reworked retrying logic to accommodate steps failing with 2+ errors.
    See https://bvckup2.com/wip/04062020 for details.

    ⦁ Reworked backup summary wording to be more precise in presence of errors and retries. See the above link for details.

    ⦁ Reworked logging to preserve original IDs of steps when they are retried. This is a purely cosmetic fix. Previously, when a backup step was retried, it would appear in the log under a new step ID. Now the ID is preserved, so it's easier to find all retries of the same operation.

    ⦁ Reworked name case changing logic to handle certain case better.

    More specifically, if both file's and its parent folder's names need a case change (on the backup side), then in some cases these two changes will be made _exactly_ in parallel, resulting in some rather obscure errors (e.g. "the file in use" reported for the folder rename). The fix was to sequence these operations, so that one is executed after the other.

    Kudos to Mike for reporting this.

    ⦁ Reworked auto-update option to not require a production license. Previously, when the program is set to auto-update itself, it wouldn't do that if there was no valid license. For the life of me I can't recall why it was done this way, but regardless of that this restriction is now removed.

    ⦁ Fixed an issue on Windows XP with handling backup cancellation. This had to do with certain Windows function being not available on XP and re-implemented using another, XP-specific API, which in turn appears to have been documented incorrectly, so things weren't working as designed.

    And, yes, someone did actually run into this issue, so they ARE still on XP.

    I know I have questioned the speed of the backups in the past, but wow, now it backups before my eyes. Lovely... :thumb:

    Bvckup 2 v81.6 Released (August 7, 2020)
    Website / Download: https://bvckup2.com/update
    Release Notes
    Release 81.6

    ⦁ Fixed handling of corrupted files in the copying module.

    This covers a particularly exotic case when a backup copy gets corrupted (at rest!) in a way that still allows extending it, but prevents it to be trimmed to the exact size. Basically, we would append, say, 1 MB to such file and then ask it to be trimmed to exactly that new size - and the latter request will fail. Copying module didn't handle it terribly well because of an overly strict internal check. Removed the check, solved the problem. The end.

    ⦁ Fixed handling of certain exclude/include rule combos - this has to do with https://bvckup2.com/support/forum/topic/499/7211

    Kudos to @highend for the report.

    ⦁ Fixed an issue with the file tree browser.

    When the Backup Settings > Backup What window is opened, the file/folder selection widget starts populating the tree. It's a process that may take a while and it runs in the background. The issue was that if the window is OK-closed while the tree wasn't fully populated, any existing excl/incl rules that applied to not-yet-discovered items were discarded.

    Kudos to Eden for the report.

    ⦁ Improved file tree browser rendering performance - tangentially related to the previous item, basically improved the rendering speed of the widget by at least a factor of 2. Beware of the temptation to use WM_SETREDRAW, use with utmost care and only after due testing.

    Also added an explicit indicator of whether the background scan is still in progress or not - https://bvckup2.com/wip/r81-6-scanning-spinner.gif

    ⦁ Revised symlink verification logic in the scanning module.

    In later 79 releases the scanning module got a new check, whereby it would query the attributes of a location that a symlink is pointing at and would complain and ignore the symlink if the query fails. Now, as you can probably guess, in some cases this check misfired. More specifically, it will fail when backing up from a remote share and the symlink points at a location that is local to the remote machine.

    Kudos to Milan for the report.

    Bvckup 2 v81.9 Released (October 16, 2020)
    Website / Download: https://bvckup2.com/update
    Release Notes
    Release 81.9
    ⦁ Added preliminary support for Blake3 and xxHash3 hashers - these can now be optionally used with delta copying, and they will become the new defaults with R82. Current defaults are the original xxHash and Blake2b [1], which are already fast, but still several times slower than the new variants.

    ⦁ Fixed an issue with delta copying stats reporting - in some cases the program would erroneously report in the log that a file was copied in full whereby it was delta-updated.

    ⦁ Fixed an issue with delta state saving in presence of errors - the program would trigger a self-consistency check and shut down when it would run into a certain type of error while attempting to start delta copying of a file. This is an exotic case.

    ⦁ Fixed an issue with the mapped drive monitoring - the module that periodically checks the status of all mapped drives (with the goal of proactively detecting them going offline) wasn't starting up correctly in some cases.
