v1.3.0

Major changes

• Add support for paging. (#92 by @xuanxu)
• Allow searching by last_updated_date. (#93 by @xuanxu)
• Add submitted_at for submission date querying. (#97)
  This also changes last_updated_date from #93 to updated_at, and similarly for the last_updated and date_submitted sort-by criteria.

Minor changes

• Update Arx() to match new Arx.search signature (from #92). (#94)
• Change incorrect lastUpdated sort-by criterion to lastUpdatedDate. (#96)
• Add to_s methods for Arx::Paper, Arx::Author and Arx::Category. (#99)
• Add fix for JSON warning in Ruby >=2.7. (#101)
• Add contributors section to README.md. (#102)

v.1.2.1

Major changes

• Add support for saving PDFs with Paper#save (see #81). (#90)
• Change gem Ruby version specifier from ~> 2.5 to >= 2.5. (#86)

Minor changes

• Remove arXiv logo from README.md. (#87)
• Use URI.open instead of Kernel.open (see #82). (#86)
• Add CI rubies 2.7 and 3.0 (see #84). (#86)

v1.2.0

Major changes

• Adds serialization support through the following methods (#63):
  • to_h: Serialize into a Ruby hash (with symbol keys). Accepts a boolean argument, representing whether or not to deep-serialize nested Author and Category objects (defaults to false).
  • as_json: Serialize into a Ruby hash which is also a valid JSON hash.
  • to_json: Serialize into a valid JSON string.
• Remove version filter from query ID list. (#69)

  Previously, all of the following would return the latest paper, 1807.06918v2:

  Arx.get('1807.06918').version #=> 2
  Arx.get('1807.06918v1').version #=> 2
  Arx.get('1807.06918v2').version #=> 2

• Adds ATTRIBUTES constant for Paper, Author and Category entities, as a list of which attributes are available for the entity. (#63)
• Remove key-word arguments from Paper#id and Paper#url. (#70)

  Previously, Paper#id and Paper#url accepted a version key-word argument, which was a boolean variable indicating whether or not to include the version number in the ID or URL.

  This has now been changed to a regular argument, which still defaults to false.

  paper = Arx.get('cond-mat/9609089')
  
  # Old (no longer works)
  paper.id(version: true)
  paper.url(version: true)
  
  # New
  paper.id(true) #=> "cond-mat/9609089v1"
  paper.url(true) #=> "http://arxiv.org/abs/cond-mat/9609089v1"
