* Until version 41 (bug 1162299) any features in the blocklist would be interpreted as "all features" by the versions that do not know about those features. For example, FEATURE_STAGEFRIGHT was added in Gecko version 17. If FEATURE_STAGEFRIGHT was added to the downloadable blocklist, all versions prior to version 17 would automatically block all features that otherwise match that blocklist entry. | * Until version 41 (bug [https://bugzilla.mozilla.org/show_bug.cgi?id=1162299 1162299]) any features in the blocklist would be interpreted as "all features" by the versions that do not know about those features.

* Until version 41 (bug 1162530) all blocklist entries applied to all Gecko versions. We introduced the graphics blocklist entry versioning, which let us specify the minimum and maximum version that any particular blocklist entry applies to. Note that the versions include nightly/aurora/beta suffixes, so if you wanted a blocklist entry to apply to all versions after version 42, for example, you would specify minVersion as 43.0a1. | * Until version 41 (bug [https://bugzilla.mozilla.org/show_bug.cgi?id=1162530 1162530]) all blocklist entries applied to all Gecko versions.

* Downloadable blocklists are usually only downloaded once a day, and cached in the profile directory (as blocklist.xml.) Modifying that file is often the best way to do local testing of changes, before proceeding with the staging of the modified blocklist file. | * Downloadable blocklists are usually only downloaded once a day, and cached in the profile directory (as blocklist.xml.)
