Adobe this morning released an update to Lightroom Classic – 7.3.1 – only two weeks after releasing 7.3. This interim update provides important bug fixes only – no new camera support or lens profiles, and no new features.

Preset and Profile Bugs Fixed

Note that many users are experiencing slowdowns when hovering over presets, given the new behavior in 7.3 of this generating a preview in the main window rather than just in the Navigator panel. Adobe does plan to allow you to turn this behavior off in Preferences – but this didn’t make it into 7.3.1. If you’re experiencing slowdowns as a result of this preset preview and you’d like to try out Adobe’s preference fix before it’s available to the general public, leave a comment below.

Backup Catalog Corruption Bug Fix

Adobe has discovered that some catalog backups made during the 7.0-7.3 timeframe are being corrupted as they are written, due to a rare condition in the code. This issue has been fixed in 7.3.1 so backups made from now on should not be corrupted.  For this reason in particular, it is important to update to 7.3.1, and then to backup your catalog so that you can be sure that you have 1+ backups that are not corrupted. If you don’t want to update to 7.3.1 right away, then regularly make a manual copy of your catalog (.lrcat) file to have as a backup. To see where you catalog file is, go to Edit (PC) or Lightroom (Mac)>Catalog Settings – the location and the file name are listed on the General tab.

Note that 7.3.1 will not zip up backups of catalogs smaller than 4 GB on Mac. This will be fixed in the next update. Having backups zipped (i.e. contained in .zip files) protected us from accidentally launching Lightroom with one of these backups and unknowingly working with a backup rather than with our master catalog. Until the next update therefore, be extra careful not to double-click on a catalog backup. (Stay out of the date folders in your Backups folder.) You can manually zip a backup file if you wish – right-click on the file and choose Compress.

How to Update

To update, go to Help>Updates, and in the Creative Cloud application that launches, click on Update next to Lightroom Classic CC. If there is no update available, then click on the three vertical dots in the top right and choose Check for App Updates. If that fails to find an update, then click on your profile (next to the three dots), sign out, and sign in again. If that fails and it’s launch day, then try again later.

Whether to Update

This is an important update. Nevertheless, as long as you make a manual copy of your catalog to serve as a backup, it can’t hurt to wait a few days to see whether the update introduces new issues.  Check back on this post (rather than writing to me) – if there are widespread serious issues, I will update this post (but I won’t update it with every bug reported). No news is good news. You can also track reports of issues and report your own issues on Adobe’s bug/feedback site for Lightroom Classic – Adobe engineering staff participates here. They can’t fix what they don’t know of, so do report any issues you encounter!

Update April 25: It seems like a great deal of the issues reported for 7.3 are not being reported for 7.3.1 – it is quieter, at least so far. That said, there still are known issues, such as:

I do think that generally it’s an update that is worth installing. If you do experience issues you can’t live with, here’s how to easily roll back to 7.3 or 7.2.
