Add-on Updater 21.07 is now available. As the name suggests, you can use Add-on Updater to update Add-on Updater.
Add-on Updater 21.07 is a major update. When it first appeared in 2018, Add-on Updater was designed to retrieve updates to add-ons hosted on community add-ons website. The mechanism involved downloading add-on update information from community add-ons website through a PHP file, which didn’t really check for NVDA compatibility information. Starting with version 21.07, Add-on Updater will use a much improved secondary source (a JSON file hosting add-on metadata) to check for NVDA compatibility before offering updates to add-ons you are using. The biggest difference is that this secondary source will also let Add-on Updater learn about new add-ons added to community add-ons website whenever they are published, which reduces add-on maintenance burden significantly (some add-on releases were dedicated to registering new add-ons for update checks; now all this will be done via JSON add-on metadata).
Another big change with Add-on Updater 21.07 is that, on Windows 10 and 11 (preview), you will receive a toast notification when add-on updates are available. Previously if add-on updates become available, a dialog may show up. Starting with this release, a toast advising you to open NVDA menu/Tools/Check for add-on updates will be shown when add-on authors release new updates.
Last but not least, sometimes add-on developers declare their add-ons as legacy because add-on features have become part of NVDA or for other reason. Previously if Add-on Updater detected legacy add-ons, a dialog will be shown at startup, but you had to use review cursor commands to read legacy add-ons list. Starting with this release, Add-on Updater will present legacy add-ons in a list view format, letting you review legacy add-on information more easily.
But that’s not all: there will come a time when you will be asked to uninstall Add-on Updater. More on that later. For now, please install Add-on Updater 21.07 (compatible with NVDA 2020.4 and later).
