CombinePDF v0.1.6 Release Notes
-
🛠 fix: added Mutex to font library (which was shared by all PDFWriter objects) - now fonts are thread safe (PDF objects are NOT thread safe by design).
🛠 fix: RTL recognition did not reverse brackets, it should now correctly perform brackets reversal for any of the following: (,),[,],{,},<,>.
⚡️ update: updated license to MIT.
known issues: encrypted PDF files can sometimes silently fail (producing empty pages) - this is because on an attempted decrypt. more work should be done to support encrypted PDF files. please feel fee to help.
💎 I use this version on production, where I have control over the PDF files I use. It is beter then system calls to pdftk (which can cause all threads in ruby to hold, effectively causing my web app to hang).
