# 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
- Bump required Ruby slightly to 2.5
- Introduce new `REGEX_POSSIBLE` which contains the regex described in
https://www.unicode.org/reports/tr51/#EBNF_and_Regex
- Fix that some valid subdivisions were not decompressed (`REGEX_VALID`)
- 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
## 3.6.0
- `Unicode::Emoji::REGEX_TEXT` now matches non-emoji keycaps like "3⃣" (U+0033 U+20E3)
- Minor refactorings
## 3.5.0
- Emoji 16.0
## 3.4.0
- Emoji 15.1
## 3.3.2
- Update valid subdivisions to CLDR 43 (no changes)
-> there won't be any new RGI subdivision flags in Emoji
## 3.3.1
- Update valid subdivisions to CLDR 42 (no changes)
## 3.3.0
- Emoji 15.0
## 3.2.0
- Update valid subdivisions to CLDR 41
## 3.1.1
- Fix `REGEX` to be able to match complete family emoji, instead of
sub-matching partial families, thanks @matt17r
## 3.1.0
- Update valid subdivisions to CLDR 40
## 3.0.0
- Vastly improve memory usage, patch by @radarek
- Emoji regexes are now pre-generated and bundled with the release
- Regexes use character classes instead of unions when possible
- Most constants (e.g. regexes) now get autoloaded
- See https://github.com/janlelis/unicode-emoji/pull/9 for more details
## 2.9.0
- Emoji 14.0
## 2.8.0
- Update valid subdivisions to CLDR 39
## 2.7.1

## 2.7.0

## 1.0.0
- Drop support for Ruby below 2.3, use 0.9 if you need to
- Internal refactorings, no API change
## 0.9.3
- Implement native Emoji regex matchers, but do not activate or document, yet
## 0.9.2
- REGEX_TEXT: Do not match if the text emoji is followed by a emoji modifier
## 0.9.1
