As a side note, if you hit problems on 3.3.1 and want to downgrade to 3.3, pin babel-compiler to 7.12.0 in .meteor/versions. The eager 7.12.1 update introduced a mistaken change that requires the 3.3.1 tool.
To ensure more stability, we’re close to releasing patch 3.3.2. It will include improvements to the recent Mongo driver upgrade and support for legacy adopters. We’ll also fix several long-pending issues from the GitHub tracker.
Want a fix in 3.3.2? Open your PRs now so we have time to include them, or ensure issues have reproduction repository to proper planning and fixing.
We’re also working on releasing Meteor 2.16.2 to add support for Cordova 14. For now you can use a Meteor checkout to publish your Meteor 2.x apps to the Android Store and meet the new SDK 35 requirement. Stay tuned for the official 2.16.2 release.
