```

## 5.0.0

### Streams

This release is heavily focused on converting the core methods of this library to use streams. Why? Overall its made the API ~20% faster and uses only 10% or less of the memory. Some tradeoffs had to be made as in their nature streams are operate on individual segments of data as opposed to the whole. For instance, the streaming interface does not support removal of sitemap items as it does not hold on to a sitemap item after its converted to XML. It should however be possible to create your own transform that filters out entries should you desire it. The existing synchronous interfaces will remain for this release at least. Do not be surprised if they go away in a future breaking release.

### Sitemap Index

This library interface has been overhauled to use streams internally. Although it would have been preferable to convert this to a stream as well, I could not think of an interface that wouldn't actually end up more complex or confusing. It may be altered in the near future to accept a stream in addition to a simple list.

### Misc

- runnable examples, some pulled straight from README have been added to the examples directory.
- createSitemapsIndex was renamed createSitemapsAndIndex to more accurately reflect its function. It now returns a promise that resolves to true or throws with an error.
- You can now add to existing sitemap.xml files via the cli using `npx sitemap --prepend existingSitemap.xml < listOfNewURLs.json.txt`

### 5.0 Breaking Changes

- Dropped support for mobile sitemap - Google appears to have deleted their dtd and all references to it, strongly implying that they do not want you to use it. As its absence now breaks the validator, it has been dropped.
- normalizeURL(url, XMLRoot, hostname) -> normalizeURL(url, hostname)
  - The second argument was unused and has been eliminated
- Support for Node 8 dropped - Node 8 is reaching its EOL December 2019
- xslURL is being dropped from all apis - styling xml is out of scope of this library.
- createSitemapIndex has been converted to a promised based api rather than callback.
- createSitemapIndex now gzips by default - pass gzip: false to disable
- cacheTime is being dropped from createSitemapIndex - This didn't actually cache the way it was written so this should be a non-breaking change in effect.
- SitemapIndex as a class has been dropped. The class did all its work on construction and there was no reason to hold on to it once you created it.
- The options for the cli have been overhauled
  - `--json` is now inferred
  - `--line-separated` has been flipped to `--single-line-json` to by default output options immediately compatible with feeding back into sitemap

## 4.1.1

Add a pretty print option to `toString(false)`
pass true pretty print

Add an xmlparser that will output a config that would generate that same file

  cli:
    use --parser to output the complete config --line-separated to print out line
    separated config compatible with the --json input option for cli

  lib: import parseSitemap and pass it a stream

## 4.0.2

Fix npx script error - needs the shebang

## 4.0.1

Validation functions which depend on xmllint will now warn if you do not have xmllint installed.

## 4.0.0

This release is geared around overhauling the public api for this library. Many
options have been introduced over the years and this has lead to some inconsistencies
that make the library hard to use. Most have been cleaned up but a couple notable
items remain, including the confusing names of buildSitemapIndex and createSitemapIndex

- A new experimental CLI
  - stream in a list of urls stream out xml
  - validate your generated sitemap
- Sitemap video item now supports id element
- Several schema errors have been cleaned up.
- Docs have been updated and streamlined.

### breaking changes

- lastmod option parses all ISO8601 date-only strings as being in UTC rather than local time
  - lastmodISO is deprecated as it is equivalent to lastmod
  - lastmodfile now includes the file's time as well
  - lastmodrealtime is no longer necessary
- The default export of sitemap lib is now just createSitemap
- Sitemap constructor now uses a object for its constructor

```js
  const { Sitemap } = require('sitemap');
  const siteMap = new Sitemap({
    urls = [],
    hostname: 'https://example.com', // optional
    cacheTime = 0,
    xslUrl,
    xmlNs,
    level = 'warn'
  })
```

- Sitemap no longer accepts a single string for its url
- Drop support for node 6
- Remove callback on toXML - This had no performance benefit
- Direct modification of urls property on Sitemap has been dropped. Use add/remove/contains
- When a Sitemap item is generated with invalid options it no longer throws by default
  - instead it console warns.
  - if you'd like to pre-verify your data the `validateSMIOptions` function is
  now available
  - To get the previous behavior pass level `createSitemap({...otheropts, level: 'throw' }) // ErrorLevel.THROW for TS users`

## 3.2.2

- revert https everywhere added in 3.2.0. xmlns is not url.
- adds alias for lastmod in the form of lastmodiso
- fixes bug in lastmod option for buildSitemapIndex where option would be overwritten if a lastmod option was provided with a single url
- fixes #201, fixes #203

## 3.2.1

- no really fixes ts errors for real this time
- fixes #193 in PR #198

## 3.2.0

- fixes #192, fixes #193 typescript errors
- correct types on player:loc and restriction:relationship types
- use https urls in xmlns

## 3.1.0

- fixes #187, #188 typescript errors
- adds support for full precision priority #176

## 3.0.0

- Converted project to typescript
- properly encode URLs #179
- updated core dependency

### 3.0 breaking changes

This will likely not break anyone's code but we're bumping to be safe

- root domain URLs are now suffixed with / (eg. `https://www.ya.ru` -> `https://www.ya.ru/`) This is a side-effect of properly encoding passed in URLs
