PDFTextStream v2.6.0 was released today with a variety of small new features and a couple of bugfixes. The bigger change is that PDFTextStream is now available free for use in single-threaded applications.
Because of the realities of the economics around developing and maintaining a product like PDFTextStream, its pricing has often been out of reach of many projects and very small organizations that really need high-quality PDF content extraction functionality. That's not to say that PDFTextStream is overpriced — it's actually less expensive than other options — but that is small comfort to many that simply cannot afford or cannot justify the expenditure yet.
This change should fix that: if you have a smaller project, are working on a startup, are involved in information research, etc., you can now benefit from all that PDFTextStream has to offer. And, if and when your architecture requires concurrent PDF processing, or your PDF content extraction workload is large enough to need to worry about properly utilizing your hardware and compute resources, you can easily upgrade to the unlimited, licensed "edition" of PDFTextStream to parallelize that workload.
It will be fun to see what people build now that PDFTextStream is gratis. Try it out!
