Separate Builder

XML Builder was the part of fast-xml-parser for years. But considering that any bug in builder may false-alarm the users who are only using parser and vice-versa, we have decided to split it into a separate package.

Migration

To migrate to fast-xml-builder;

From

import { XMLBuilder } from "fast-xml-parser";

To

import  XMLBuilder  from "fast-xml-builder";

XMLBuilder will be removed from current package in any next major version of this library. So better to migrate.

support strictReservedNames

Sourced from fast-xml-parser's changelog.

Note: If you find missing information about particular minor version, that version must have been changed without any functional change in this library.

Note: Due to some last quick changes on v4, detail of v4.5.3 & v4.5.4 are not updated here. v4.5.4x is the last tag of v4 in github repository. I'm extremely sorry for the confusion
