Changelog

The UpdraftPlus backup blog is the best place to learn in more detail about any important changes.

N.B. Paid versions of UpdraftPlus Backup / Restore have a version number which is 1 higher in the first digit, and has an extra component on the end, but the changelog below still applies. i.e. changes listed for 1.16.32.x of the free version correspond to changes made in 2.16.32.x of the paid version.

1.16.62 – 30/Sep/2021

• FIX: Fix UpdraftCentral error when installing plugin or theme on a slow connection
• TWEAK: Support wildcard (asterisk char) exclusions not just for the first/top-level directory but also for the 2nd level directories and below
• TWEAK: Fix deprecation warning on UpdraftCentral’s comment settings

• TWEAK: Add admin and log warning messages regarding the planned shutdown of Microsoft Azure and OneDrive Germany

• TWEAK: Existing backups paging logic to avoid a confusing rescan user experience

1.16.61 – 28/Aug/2021

• FIX: If MySQL performance was very fast on large tables, and if fallback fetch mode was being used (which should not occur on any WordPress core table, but can be triggered on recent Oracle MySQL 8.0 versions), then when increasing rows fetched on large tables, some rows could be unintentionally skipped.
• TWEAK: Oracle MySQL 8.0 from somewhere after 8.0.17 has removed the display width from the response to SHOW CREATE TABLE, resulting in failure (prior to this tweak) to detect a primary key type that can be used with faster fetching

• TWEAK: Improvements in finding a working mysqldump binary during a backup operation
• TWEAK: Start on larger chunk sizes when fetching *meta table contents, and scale up chunk sizes on all tables dynamically (less SQL queries; but testing shows it makes little difference to overall speed)

• TWEAK: Show a notice when attempting to download a backup from email remote storage explaining nothing can be downloaded

• FEATURE: Backup destinations with conditional logic rules for scheduled backups (Premium)
• FIX: A regression in 1.16.30 meant that the term_relationships table could have rows missing in the backup if mysqldump was not present/used; this meant that items with multiple terms were only having one relationship backed up (e.g. multiple tags being assigned to one post)

• TWEAK: Rename UpdraftCentral’s main and listener classes
• TWEAK: Improve error message when encrypted key given by user for SFTP/SCP remote storage method

• TWEAK: Integrate UpdraftPlus and WordPress 5.5 core’s automatic update settings
• TWEAK: When a backup resumed, the last successful resumption was incorrectly set as the last successful resumption when an ‘alive’ event was recorded, rather than a ‘useful’ one; this deferred some mitigations when there was insufficient progress

• TWEAK: Remove the now-redundant concept of inner loops from the database table backup routine

1.16.31 – 20/Oct/2020

• FIX: A regression in 1.16.30 meant that tables with integer primary keys which used signed integers omitted the first row of the table from the backups. This is not common (e.g. it does not affect any core WP tables; most plugins adding tables follow WP core in using unsigned integers for primary keys).

1.16.30 – 15/Oct/2020

• PERFORMANCE: Where a table has a numerical primary key, extract its data using that index. This results in a substantial performance increase when fetching large tables using PHP. (The filter updraftplus_can_use_primary_key_default can be used to de-activate this behaviour).
• FIX: Remove incorrect decodeURIComponent() parsing when importing settings, which could prevent import of settings containing some special characters
• FIX: An issue where database tables that were not selected to be backed up in a “Backup Now” backup would get added to the backup during a resumption (i.e. if it did not finish in a single run)

• TWEAK: Show a notification of UpdraftPlus plugin updates even if the associated user account is not connected to the UpdraftPlus website
• TWEAK: Add mechanism to detect what hosting provider is being used and use it to make UpdraftPlus comply with Kinsta’s backup limit policies (thus removing it from the list of disallowed plugins)
• TWEAK: When booting a clone if it’s claimed from the clone queue then update the token being used
• TWEAK: Tweaked downwards the minimum time in the future for rescheduling a resumption

1.16.29 – 08/Sep/2020

• NOTE: The free version 1.16.27 was released as 1.16.26; i.e. if confused about 1.16.26 went, then the answer is that they are the same thing.

1.16.25 – 23/May/2020

• FIX: Dropbox since 1.16.24 was only deleting one backup files archive out of the set. i.e. Excess archives remained on Dropbox. These have to be deleted manually.

• REFACTOR: Completed re-factoring of the remote storage modules, so that now all remote storage code has completed this current stage of re-factoring (more to come in future – laying the foundation for a significant new feature)
• FIX: Added a nonce to the Dropbox deauth link. This is a minor security issue – someone personally targetting you, who knew that you were logged in to your WordPress admin, and who could persuade you to visit a personally-crafted web page, could cause the connection between UpdraftPlus and your Dropbox to be broken. The only impact of this is that the sending of your next backup to Dropbox would fail, and you would be alerted about the need to re-connect.

• TWEAK: Remove debugging statement inadvertently left in 1.12.36
• TWEAK: Re-factored remote storage handlers via add-ons so that there was a cleaner and more consistent class hierarchy (preparation for future improvements). N.B. If you subsequently downgrade to an older version of UpdraftPlus, you will need to re-enter the settings for some remote storage options.
• TWEAK: List of checksum algorithms run over backups and logged now includes SHA256, and is filterable (SHA1 now considered deprecated)
