BEM news digest - Githubissues

Brief news about the BEM world since the beginning of this year:

Documentation news

Rolled out the BEM libraries section in a new design on bem.info:

Released bem-core 4.1.0 and 4.1.1. All changes of the both releases are described in a CHANGELOG.

Released bem-components v4.0.0 with update of controls design and with the transition from the Stylus to postCSS.
Released bem-components 5.0.0 that used bem-core 4.1.1. There are two style sets in v5.0.0: source files with postCSS and compiled CSS in case you prefer to use some preprocessor.

Not yet released but is already used in a separate branch v4. This version is compatible with bem-core v4. Feel free to try, revise and send us a feedback before we release a new version. The major change is rename of uri block to uri__querystring element, which extends the basic implementation of the same name module in bem-core with Uri class. Class methods remained unchanged.

Working on BEM React Core — a core library for develop with React and BEM methodology.
Released a complete documentation package: README, REFERENCE и CONTRIBUTION GUIDE.

Released the following major updates:

Updated bem-core to 4.1.1 and bem-components to 5.0.0.
Began to use PostCSS instead of Stylus. We provide the same set of plugins that bem-components has.
Implemented an optional livereload. For details read the documentation and [README](https://github.com/bem /bem-express/blob/master/README.md) of the project.
Achieved the speed acceleration of the build procedure by updating npm-modules required for assembly.
Abandoned bower to supply libraries. Now all dependencies are set through npm in node_modules directory.

v8.3.1 (v7.4.1)
- extend() mode fixed. Now it works as expected.
- Documentation updated: this.extend(o1, o2) description added.
v8.4.0 (v7.6.0)
- New unquotedAttrs option allows us to ommit unnececary quotes of HTML attributes in some cases.
v8.4.1 (v7.6.1)
- extend(function(ctx, json) { … }) mode callback now have two arguments, the same as have the callbacks of other modes. The first argument is a link to context of (this) template execution. The second — link to a BEMJSON node.
v8.4.2
- Escaping functions fixed: now argumengs undefined or null and NaN will give you empty string as a result. In previous versions you get stringified results ('undefined', 'null', 'NaN').
v8.5.0
- BEMTREE: added modes related to data: js(), addJs(), mix(), addMix(), mods(), addElemMods(), elemMods(). The rest of the modes that are relevant only to-HTML are available in BEMHTML.
v8.5.1
- Fixed bug: calculate position if block/elem was replaced via replace().
v8.5.2 (v7.6.4)
- Fixed bug in BEMTREE related to the rendering of special value field content { html: '<unescaped value>' }.
- bem-xjst onlinе demo updated:
  - Added a switch of BEMHTML/BEMTREE engines.
  - Added a plug for BEM.I18N (), which returns its second argument. This is useful to copy the code from production to a sandbox.
- README updated.
- A sandbox updated. You could help our projest to fix issues with help wanted lable.

Released a new version of enb-bemxjst v8.5.2 with "dependencies": { "bem-xjst": "8.5.2" }. However, we continue to actively support the both branches: 7.x and 8.x.

All changes are described in releas notes v8.5.2 and v7.6.4 and in a CHANGELOG.

Released bem-tools 2.0.0 with updated bem-tools-create. Detailed description is in README.

Wrote a full and clear README.

Implemented a new version of bem-components v5.0.0 taking into account the transition to postCSS and a new version of bem-tools 2.0.0.
As an experiment, included gulp-bem in a project-stub.
