0.24.4 release * NSCL update: various improvements of the MutationObserver patching introduced by 0.24 and later * Update translations (mainly es affected, minor changes in pt and uk)

0.24.3 release * Firefox-only: [Update NSCL to 13.6.27.901](https://lists.nongnu.org/archive/html/js-shield/2026-07/msg00007.html), Fix TypeError: newTarget is not a function (SyncMessage.js:710:26)

0.24.1 release * NSCL Update related to a bug in script injection to Firefox where 0.24 hid MutationObserver.prototype from page scripts (that might break pages requiring the prototype and/or reveal that JShelter or similar webextension is installed). See https://github.com/hackademix/noscript/issues/572 and https://github.com/hackademix/nscl/commit/e0849aa9df8d47d36b9beb3b21f4c92a5f06792a for the context. * Added translation languages: es, pt, uk

0.24 release * NSCL update: * Improved corner-cases in script injection in both Firefox and Chromium-based browsers. * Avoid issues related to MutationObservers, see [https://lists.nongnu.org/archive/html/js-shield/2026-06/msg00003.html](the mailing list) and the related thread * Set Workers to Strict by default, see https://codeberg.org/JShelter/webextension/issues/156 and https://codeberg.org/JShelter/webextension/issues/177 for the reasoning. * Reconsider the approach to modify Web Audio that was reimplemented in 0.22. The farbling (recommended level) essentially returns to the original concept but the memory footprint of JShelter improves as it uses WeakMaps to store farbled Web Audio buffers for the duration of their existance. The approach to farble floats in the Web Audio API changed slightly to avoid revealing the lower bound of the readings and to farble 0s. This approach should brake less page scripts. The white noise has very limited amplitudes close to a silence. page scripts. * Allow users to configure JShelter not to interfer with pages where their disable both JSS and FPD. * Do not show NSCL log messages as they may confuse users

0.23.1 release * Update NSCL that improves handling of script injections, especially failure management, transition handling and performance.

0.23 release * Avoid userScript permission in Chromium-based browsers (this is a major redesing of the mechanism to inject modifications to JavaScript APIs visible to page scripts - main world). Note that the code was not provided by a member of the core team and does not contain some changes made in the last 5 years, see [the related issue](https://codeberg.org/JShelter/webextension/issues/181). The code for Firefox is almost the same and functionally equivalent to 0.22.1. * Quietly discard possible exceptions that were thrown in 0.22.1, which [fixes the interaction with AdGuard](https://codeberg.org/JShelter/webextension/issues/179). * Update NSCL to 13.6.20 (latest version). It should provide several changes to JShelter, including avoiding contentScript.register() (see [issue #175](https://codeberg.org/JShelter/webextension/issues/175)). * Refactor mechanism to determine when to propagate detected API calls to background introduced in 0.22.1. The mechanism should be essentially the same but behave better on some pages.

0.21 release * Add support for `Temporal.Now.instant()` that provides precise timestamps * Refactor code for modifications of timestamps to be more readable as well faster

0.20.4 release * Fix issues with translation strings introduced in 0.20.3 * ru translation at 100% again

0.20.3 release * Chromium-based browsers: Handle [userScripts API permissions change](https://pagure.io/JShelter/webextension/issue/166) * Update ru and cs strings * Add fi, fr, pl, and pt\_BR translations that have only about [20-60% of strings translated](https://lists.nongnu.org/archive/html/js-shield/2025-06/msg00000.html).

0.20.2 release * Avoid web accessible resources in Chrome-based browsers to prevent simple and precise JShelter detection by page scripts at the cost of slight performance decrease, see [the commit message for details](https://pagure.io/JShelter/webextension/c/b4cffc1dd17851cb258e6a8ba73d6572fb9d8514?branch=main) * Update NSCL (code refactoring and removal of debug statements from non-debug runs) * Change messages about failures in WASM code to warnings as these might be useful to users * Small update of Czech and English user-facing strings

0.20.1 release * Change Worker settings for pad.riseup.net (https://pagure.io/JShelter/webextension/issue/152) and kiwi.com (https://pagure.io/JShelter/webextension/issue/153) * Fine-tune strings shown in popup for FPD * Limit logging to console by JShelter (do not produce output that the user is not concerned with). Developers can see such output in debug builds.

0.20 release * More robust SyncMessage implementation * Prevent patchWindow from throwing on SOP violations. * Chromium-based: Fix bug that wrappers were sometimes not timely applied (MV3 bug of 0.19) * Firefox: Work around issue that could have prevented XML documents from being parsed/loaded by the browser (see also https://bugzilla.mozilla.org/show_bug.cgi?id=1899786) * Firefox: minimal requirements increased to 115

0.19.1 release Improve performance of FPD in temporary background scripts: Limit the amount of data that is stored to the permanent storage as well as the number of write operations without a real hit stemming from the need to recomupte the data.

0.19 Release * First Manifest V3 release, using only MV3 APIs on Chromium-based browsers. * Updated NoScript Commons Library dependency to the mv3 branch. * All browsers: fixed UI popup failing to render when opened first time after long inactivity * Chromium-only: user-facing warnings about developer mode being currently required on MV3. * Chromium-only: removed Network Boundary Shield (unimplementable in current MV3). * Chromium-only: removed blocking mode Fingerprinting Detection (unimplementable in current MV3).
