This document describes breaking changes and how to upgrade. For a complete list of changes including minor and patch releases, please refer to the changelog.
This release drops support of legacy runtime environments (Level/community#98):
- Node.js 6 and 8
- Internet Explorer 11
- Safari 9-11
- Stock Android browser (AOSP).
Upgraded to readable-stream@3 which contains several substantial changes and improvements. Since level-iterator-stream derives from readable-stream we decided to bump major as well.
Removed support for node 4.
Encodings were factored out from levelup into encoding-down and in that process they were removed from this module as well. For more information, please check the corresponding CHANGELOG.md for:
If your code relies on options.decoder for decoding keys and values you need to handle this yourself, e.g. by a transform stream or similar.
Support for node 0.10, 0.12 and iojs was also dropped.
