The support for PostgreSQL that was added in R2 was covered in an earlier blog post.  The enhancements in R3 are primarily related to addition entries added to the PBODB170.INI file.  These additional entries provide more support for maintaining tables, views, primary and foreign keys, users and groups in the database painter.  

In an article on the enhancements that were added to the stand alone compiler in R2, I remarked on an issue on how file version information was handled in the initial release, and which was still a problem in R2.  Fortunately, R3 corrects that issue.

Support for using SVN as a source control system without going through a bridge product was added in 2017 R2 and covered in a previous blog post.  In this blog post we're going to look at the enhancements that were added to that feature in 2017 R3. 

PowerBuilder 2017 R3 introduces support for encoding and encrypting data, something of particular interest when using REST web services.  We're going to take a look at those new features. 

PowerBuilder 2017 R2 added a number of REST features, which I covered in a previous blog post.  One area for improvement on the original feature was better support for REST authentication methods.  The HTTPClient and RESTClient objects provided methods to set request headers, but doing the legwork needed for some of the more complex authentication mechanism (i.e., OAuth) were left to the developer.  PowerBuilder 2017 R3 addresses that.  In this blog post we'll look at using this new feature.

There were some JSON features introduced in 2017 R2, in particular the JSONGenerator and JSONParser, which were covered in a previous blog post.  2017 R3 introduces additional important JSON features, in particular JSON import/export from a DataWindow, and a JSONPackage object that is used to merge/extract JSON data sets.  Those will be covered in this blog post.

Support for using Git as a source control system without going through a bridge product was added in 2017 R2 and covered in a previous blog post.  In this blog post we're going to look at the enhancements that were added to that feature in 2017 R3.
