christian [Release Notes for PDFtalk 2.0]
Line 3: Line 3:
 This is the release of the second major version of the PDF library in October 2017. This is the release of the second major version of the PDF library in October 2017.
  
-The previous version was called //​PDF4Smalltalk//​.+===== What's new =====
  
 +**Name** The new name is //​**PDFtalk**//​. The first version was called //​PDF4Smalltalk//​. The namespace changed from ''​PDF''​ to ''​PDFtalk''​ and the domain "​pdftalk.de"​ provides a home with a wiki dedicated to the library: [[https://​wiki.pdftalk.de|wiki.pdftalk.de]].
 +
 +**Typing** The heard of the “PDF engine” is the [[newtyping|typing system]] which allows the assignment of Smalltalk classes to raw PDF objects. The new version has a redesigned type system where PDF types are properly modeled independent from the Smalltalk class hierarchy. This allows to rename classes freely (i.e. adding prefixes) without affecting PDF types. Also, boxing of some simple objects like "​null"​ and booleans is not necessary anymore. Instead, existing classes are declared as PDF types.
 +
 +**[[PDFtalk4Gemstone|PDFtalk for Gemstone]]** The new release was triggered by a contract to port the library to Gemstone (thanks to HTS and Bob Nemec). A talk about this was held at ESUG 2017: "​PDFtalk for Gemstone"​ (slides are [[https://​www.slideshare.net/​esug/​pdftalk-for-gemstone|here]]).
 +
 +**[[GemstoneFileout|Gemstone Fileout]]** A VisualWorks to Gemstone translation tool. This tool, with project specific code transformation declarations,​ creates a Gemstone filein. Used to create the Gemstone PDFtalkLibrary from the Values package and PDFtalk bundle.
 +
 +Both new projects are open source with MIT licence.
