# CHANGELOG

## 4.2.0

- Allow Ruby 4.0
- Remove Non-Emoji pictographs from spec, since they have been removed in Unicode 17
- Update valid subdivisions to CLDR 48 (no changes)

## 4.1.0

- Unicode 17
- Update valid subdivisions to CLDR 47 (no changes)

## 4.0.4

- Add `REGEX_TEXT_PRESENTATION` to be able to match for raw default-text Emoji codepoints

## 4.0.3

- Remove emoji-test.txt from Rubygems package

## 4.0.2

- Directly use `RbConfig::CONFIG["UNICODE_EMOJI_VERSION"]` to detect Ruby's Emoji version,
  drop unicode-version dependency

## 4.0.0

- **Breaking change:** Regexes now include single skin tone modifiers (`🏻`) and hair components (`🦰`).
  They were previously considered to be invalid partial Emoji, however since they are supposed to be
  displayed as Emoji in isolation, they are now part of the regexes (see *ED-20* in UTS51).
- **Breaking change:** Drop `REGEX_ANY` in favor of `REGEX_PROP_EMOJI`
- Expose regexes for Emoji props (`REGEX_PROP_*`). The advantage over using the native regex properties
  directly is that you will be able to use the Emoji support level of this gem instead of Ruby's.
  For example, as of releasing this, the current Emoji version is 16.0, while Ruby is at 15.0.
  Also see README for a table listing the regexes that match Emoji properties.
- Add `REGEX_EMOJI_KEYCAP` for matching specifically Emoji keycaps
- Use character class instead of lookbehind for native text emoji and non-emoji pictographic regexes

## 3.8.0

- Add new RGI-based regexes `REGEX_INCLUDE_MQE` and `REGEX_INCLUDE_MQE_UQE` which allows to match
  for minimally-qualified and unqualified RGI sequences (Emoji that lack some VS16)
- Add specs running through `emoji-text.txt` and classify qualification statuses per regex
- Improve documentation and add detailed table about which regex has which features
- Native regexes: Use native Emoji props for Emoji text presentation
- Update CLDR to v46 (valid subdivisions)
- Further improvements (see commit log)

## 3.7.0

- Introduce new `REGEX_POSSIBLE` which contains the regex described in
  https://www.unicode.org/reports/tr51/#EBNF_and_Regex

- Be stricter about selection of tag characters in `REGEX_WELL_FORMED`
  - Only U+E0030..U+E0039, U+E0061..U+E007A allowed
  - Max tag sequence length
- Use native `/\p{RI}/` regex for regional indicators
- Separately autoload emoji list, so it can be loaded when other indexes
  are not needed
