Add-on Updater

  • Author: Joseph Lee, Luke Davis
  • Download stable version
  • NVDA compatibility: 2023.1-2024.2+
  • This is a would-be legacy add-on: NVDA 2023.2 includes add-on update check functionality through add-on store

This add-on brings NVDA Core issue 3208 to life: ability to check for, download, and apply add-on updates.

To check for updates after installing this add-on, go to NVDA menu/Tools/Check for add-on updates (if NVDA did notice updates, the menu item will say "Review add-on updates" followed by update count). If updates are available, a list of add-on updates will be shown, with each entry consisting of add-on name, current version, new version, and update channel. Select Update, and NVDA will download and apply updates in sequence, with a prompt to restart your NVDA shown afterwards.

The following add-ons provide built-in update feature and thus updates will not be checked via this add-on:

  • Braille Extender
  • Tienda NVDA (Spanish NVDA Community Store)

IMPORTANT NOTES:

  • Once the relevant feature is included in NVDA in the form of an add-on store with automatic updates and update notification, this add-on will be phased out. Currently, while the Add-on Store was introduced in NVDA 2023.2, and basic update notifications will be available in NVDA 2024.3, the full range of capabilities are not yet available.
  • This add-on requires Windows 10 Version 22H2 or later.
  • This add-on is not intended to be used in secure screens. If you have add-ons installed in the secure screen, even if you copy Add-on Updater to secure screen mode, Add-on Updater will not work.
  • If the new add-on updates specify a compatibility range (minimum and last tested NVDA versions) and if the NVDA version you are running does not fall within the compatibility range according to NVDA, add-on updating will not proceed.
  • Not all add-ons come with development releases. If you are not getting updates after choosing to install development versions of an add-on, switch to stable channel for affected add-ons.
  • In the NVDA settings window, while editing the settings for Add-on Updater, you may notice that the title indicates that you are editing settings for a particular configuration profile (whatever profile you had active before entering settings). This does not matter. This add-on's settings are always global.
  • On some systems (particularly computers joined to a corporate domain), add-on update check functionality may not work properly, therefore add-on updates must be downloaded manually.
  • Some features require NVDA to be installed on the computer.
  • Some add-on releases include SHA256 hash values for checking add-on package integrity (all add-ons published on add-on store include SHA256 values), and if the hash value does not match, add-on updating will fail.

Add-on settings

You can configure Add-on Updater settings from NVDA Settings screen (NVDA menu, Preferences, Settings) under Add-on Updater category. Add-on settings are as follow:

  • Automatically check for add-on updates: if checked, NVDA will check for add-on updates once every 12 hours. Automatic update checks are enabled by default on Windows client systems, and disabled by default on server systems.
  • Add-on update notification: you can choose to receive update notification as a dialog or a toast. On server systems or running a portable copy of NVDA, update notification will be shown as a dialog.
  • Update add-ons in the background (update notification is set to toast): if checked, Add-on Updater will apply updates in the background. A toast will appear informing you that add-on updates are being downloaded and installed, followed by another message announcing update results. Same limitations as add-on update notification setting and toast must be selected from the above option in order for background updates to work.
  • Do not update add-ons: you can choose add-ons that should not be updated.
  • Prefer development releases: any add-ons checked in this list will receive development (prerelease) releases.
  • Development release channel (selected add-on must be checked from prefer development releases): allows selecting development updates coming from either dev or beta channel.
  • Add-on update source: you can choose where to get updates from. Currently Add-on Updater supports downloading updates from the sources listed below. A confirmation message will be shown after changing update source.

The available add-on update sources are:

  • NV Access add-on store (default)
  • Community add-ons website
  • Spanish community add-ons catalog
  • Catalogs maintained by NVDA communities in China and Taiwan

Version 24.3/24.08

  • When NVDA starts, Add-on Updater will not present updates dialog if NVDA 2024.3 or later is in use and update notifications is set to "notify" from NVDA's add-on store settings.

Version 24.2.4

  • Fix a bug related to the fix in version 24.2.1: that bug was not fully fixed in NVDA 2023.X, because the fix relied on a change made in NVDA 2024.1. This situation is now detected and patched (josephsl/addonUpdater#22).
  • The update interval has been changed to 12 hours.
  • The readme now makes note of the update notifications available natively in NVDA 2024.3.
  • The readme has been updated to comment on an unfixable, but harmless, bug in NVDA's settings panel (josephsl/addonUpdater#8).

Version 24.2.2

  • Lower update interval to six hours.

Version 24.2.1

  • Fixes a problem wherein Updater's updates, which appear in the external channel, were shown as still updatable in the store via the stable (or other) channel. Caused by residual JSON files from old non-external installations. Now they are removed.

Version 24.2.0

  • Release compatible with NVDA 2024.1.

Version 24.01.1

  • Short life-span release which removes the legacy status introduced in late

  • Windows 10 Version 22H2 or later is required.

Version 23.08

This is the final version to support Windows 7, 8, 8.1, and 10 21H2 and earlier.

  • If add-on updates dialog is shown and then closed without installing add-ons, NVDA will no longer report no add-on updates when add-on updates are checked.
  • Add-on Updater will no longer present startup messages and perform update checks if updating a portable copy of NVDA.

Version 23.07

  • If using an NVDA release with add-on store included, a startup message will be shown informing users about the new add-on store. If this happens, add-on update results dialog will not be shown. Add-on Updater will continue to work.
  • Improved performance when checking for add-on updates from NV Access add-on store and community add-ons website update sources, particularly when no add-on updates are available.

Version 23.01

  • NVDA will check minimum Windows version for add-on updates if update source is set to NVDA community add-ons website.
  • Improved performance when downloading many ad-on updates at once. As a result, the order of add-on downloads shown in download progress dialog will be random.
  • Parts of the add-on now use Python's concurrent.futures module to improve performance, specifically update check and download processes.

Version 22.11

  • NVDA 2022.3 or later is required.

Version 22.10

  • Added catalogs from NVDA communities in China and Taiwan as add-on update sources (by Woody Tseng).

Version 22.09

  • NVDA 2022.2 or later is required.
  • NVDA will check SHA256 hash values while downloading add-on updates if the add-on update source includes hash values for add-on packages. If hash value is invalid, add-on updating will fail.

Version 22.08

  • Significant internal code reorganization and rewrites.
  • On Windows Server systems, automatic add-on update check feature is disabled by default (affects new installations).
  • Added ability to select different add-on update sources. Add-on Updater can check for updates hosted on community add-ons website (addons.nvda-project.org) or Spanish community add-ons catalog (nvda.es). A new combo box was added in add-on settings panel to select add-on update source.
  • On Windows 10 and later, it is possible to let Add-on Updater check for, download, and install add-on updates in the background provided that NVDA is actually installed and ad-on update notification is set to toast.
  • Redesigned add-on update download and install experience for multiple add-on updates, including use of a single dialog to show download progress for all add-ons and updating add-ons after downloading all of them.
  • If NVDA is set to announce update notifications as toasts, "check for add-on updates" menu item will become "review add-on updates" when updates become available, with the new name including add-on update count.
  • In NVDA 2022.1 and later, Add-on Updater can process command-line switches for this add-on (currently none).
  • In add-on updates dialog, add-ons disabled by the user are unchecked by default, and a confirmation message will be shown checking disabled add-ons and attempting to update them as doing so will enable them.

  • Add-on Updater will no longer check minimum Windows release information for add-ons as add-ons such as Windows App Essentials provide better Windows compatibility information.

Version 21.07

  • On Windows 10 and later, a toast notification will be shown when add-on updates are available. Note that you cannot click this notification - you must open NVDA menu/Tools/Check for add-on updates to review updates.
  • When legacy add-ons dialog is shown at startup, you can now review legacy add-ons and reasons just like add-on updates.
  • Improved add-on update check internals, including use of add-on metadata collection provided by the community to validate add-on compatibility. Among other things, this eliminates add-on releases for adding update checks for new add-ons.

Version 21.05
