Additional folders have been introduced called locales and readmes where translation files can be found. A number of features and bug fixes are also included in this release.

## Supported Release 4.16.0
### Summary

This release sees a massive update to all unit tests to test UTF8 characters. There are also multiple cleanups in preparation for internationalization. Alongside this, improvements to ipv6 support, a new length function compatible with Puppet 4, and an update to path types. Also contains multiple bug fixes around functionality and tests.

#### Features
- Addition of coverage in all unit tests for functions, data and resource types for UTF8 for i18n.
- All strings within the readme and functions that are split over two lines have been combined in preparation for i18n parser/decorator.

- Adds a new parameter `encoding` to allow non UTF-8 files to specify a file encoding. This prevents receiving the error message "invalid byte sequence in UTF-8" when special characters that are not UTF-8 encoded appear in the input stream, such as the copyright symbol.
- Addition of the new length function. Returns the length of a given string, array or hash. To eventually replace the deprecated size() function as can handle the new type functionality introduced in Puppet 4.
- Permit double slash in absolute/Unix path types.

## Supported Release 4.13.1
### Summary

This bugfix release addresses the `undefined method 'optional_repeated_param'` error messages seen by users of puppet 3.7.

It also improves the user experience around function deprecations by emitting one warning per function(-name) instead of only one deprecation overall. This allows users to identify all deprecated functions used in one agent run, with less back-and-forth.

#### Bugfixes

* Emit deprecations warnings for each function, instead of once per process. (MODULES-3961)
* Use a universally available API for the v4 deprecation stubs of `is_*` and `validate_*`. (MODULES-3962)
* Make `getvar()` compatible to ruby 1.8.7. (MODULES-3969)
* Add v4 deprecation stubs for the `is_` counterparts of the deprecated functions to emit the deprecations warnings in all cases.


## Supported Release 4.13.0
### Summary

This version of stdlib deprecates a whole host of functions, and provides stepping stones to move to Puppet 4 type validations. Be sure to check out the new `deprecation()` and `validate_legacy()` functions to migrate off the deprecated v3-style data validations.

Many thanks to all community contributors: bob, Dmitry Ilyin, Dominic Cleal, Joris, Joseph Yaworski, Loic Antoine-Gombeaud, Maksym Melnychok, Michiel Brandenburg, Nate Potter, Romain Tartière, Stephen Benjamin, and Steve Moore, as well as anyone contributing in the code review process and by submitting issues.

Special thanks to [Voxpupuli's](https://voxpupuli.org/) Igor Galić for donating the puppet-tea types to kickstart this part of stdlib.


#### Deprecations
* `validate_absolute_path`, `validate_array`, `validate_bool`, `validate_hash`, `validate_integer`, `validate_ip_address`, `validate_ipv4_address`, `validate_ipv6_address`, `validate_numeric`, `validate_re`, `validate_slength`, `validate_string`, and their `is_` counter parts are now deprecated on Puppet 4. See the `validate_legacy()` description in the README for help on migrating away from those functions.
* The `dig` function is provided by core puppet since 4.5.0 with slightly different calling convention. The stdlib version can still be accessed as `dig44` for now.


#### Features
* Add Puppet 4 data types for Unix, and Windows paths, and URLs.
* Add `deprecation` function to warn users of functionality that will be removed soon.
* Add `validate_legacy` function to help with migrating to Puppet 4 data types.

* Add `any2bool` function, a combination of of `string2bool` and `num2bool`.
* Add `delete_regex` function to delete array elements matching a regular expression.
* Add `puppet_environmentpath` fact to expose the `environmentpath` setting.
* Add `regexpescape` function to safely insert arbitrary strings into regular expressions.
* Add `shell_escape`, `shell_join`, and `shell_split` functions for safer working with shell scripts..

* The `delete` function now also accepts regular expressions as search term.
* The `loadyaml` function now accepts a default value, which is returned when there is an error loading the file.

#### Bugfixes
* Fix `file_line.match_for_absence` implementation and description to actually work. (MODULES-3590)
* Fix `getparam` so that it can now also return `false`. (MODULES-3933)
* Fix the fixture setup for testing and adjust `load_module_metadata` and `loadjson` tests.
* Fix `defined_with_params` to handle `undef` correctly on all puppet versions. (PUP-6422, MODULES-3543)
* Fix `file_line.path` validation to use puppet's built in `absolute_path?` matcher.

#### Minor Improvements
* README changes: improved descriptions of `deep_merge`, `delete`, `ensure_packages`, `file_line.after`, `range`, and `validate_numeric`.
* The `getvar` function now returns nil in all situations where the variable is not found.
* Update the `dig44` function with better `undef`, `nil`, and `false` handling.
* Better wording on `str2bool` argument validation error message.


### Known issues
* The `validate_legacy` function relies on internal APIs from Puppet 4.4.0 (PE 2016.1) onwards, and doesn't work on earlier versions.
* Puppet 4.5.0 (PE 2016.2) has a number of improvements around data types - especially error handling - that make working with them much nicer.
