# Upgrade Guide
|
||
|
|
|
||
|
|
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](CHANGELOG.md).
|
||
|
|
|
||
|
|
## v9
|
||
|
|
|
||
|
|
Dropped node 0.12, 4, 5 and 7.
|
||
|
|
|
||
|
|
## v8
|
||
|
|
|
||
|
|
Previously the "utf8" decoder always returned a string. This was a workaround for `encoding-down` that is no longer needed. The return type now depends on the `asBuffer` option, which is more optimal.
|
||
|
|
|
||
|
|
## v7
|
||
|
|
|
||
|
|
Dropped node 0.10 and iojs.
|
||
|
|
|
||
|
|
## v6
|
||
|
|
|
||
|
|
The `createDecodeStream()` method (introduced in the last 5.x version) has been replaced with `createStreamDecoder()`.
|
||
|
|
|
||
|
|
## v5
|
||
|
|
|
||
|
|
This is a rewrite of both internals and the public API. Please see the README for details.
|
||
|
|
|
||
|
|
## v4
|
||
|
|
|
||
|
|
Removed default encoding ("utf8"). If you relied on this behavior you must now define it yourself.
|
||
|
|
|
||
|
|
## v3
|
||
|
|
|
||
|
|
Removed the `encoding` option in favor of `keyEncoding` and `valueEncoding`. Note: it was partially restored in v6.1.0.
|
||
|
|
|
||
|
|
## v2
|
||
|
|
|
||
|
|
The function signature of `batch()` has changed from `batch(ops, batchOptions, dbOptions)` to `batch(ops, optionObjects)`.
