Amber v2.0.0-beta.6 released!

Amber v2.0.0-beta.6 has been released.

Amber 2.0.0-beta.6

Amber 2.0.0-beta.6 takes libxml2 out of every Amber V2 application. Until
this release, every V2 app linked libxml2, and with it liblzma, because the
schema layer could parse XML request bodies. XML is now opt-in, and the
opt-in is Mica, a pure-Crystal XML parser, so an application that accepts
XML still links no XML library.

What changed

• XML request bodies are opt-in (#1414). The libxml2-backed
  Amber::Schema::Parser::XMLParser is removed. A request sent as
  application/xml, text/xml or any +xml type is answered with
  415 Unsupported Media Type unless the application registers a parser.
• ParserRegistry.register_body_parser (#1414) lets an application add
  a request body format with one call at boot. A parser that raises answers
  the request with 400 invalid_request_body.
• CI is pinned (#1420): Crystal 1.22.1 tarballs checked by sha256,
  GitHub Actions by full commit SHA, the CircleCI image by digest,
  dependencies from a committed shard.lock with --frozen, and a second job
  that builds crystal-alpha from an exact commit and runs the suite on it.
• Specs pass on Crystal 1.22 (#1418), which rejects the empty request
  resource and the malformed multipart fixture some specs used.

Turning XML back on with Mica

Add Mica v0.1.0
(release,
commit 6a4866e) to shard.yml:

dependencies:
  mica:
    github: amberframework/mica
    version: 0.1.0

Register it in config/initializers/request_body_parsers.cr, and make sure
config/application.cr loads the initializers (require "./initializers/*";
applications generated by Amber CLI 2.0.6 load config/*.cr only):

require "mica/xml/fields"

{"application/xml", "text/xml"}.each do |media_type|
  Amber::Schema::Parser::ParserRegistry.register_body_parser(media_type) do |body|
    Mica::XML::Fields.read(body)
  end
end
