tabula 1.1.0-beta.1 / tabula-java 0.9.0

We're proud to announce the first public beta preview of Tabula 1.1! This version contains several bugfixes and a rewrite of our processing backend which should provide a significant performance increase.

This is a beta release: because Tabula utilizes a new processing backend, users may encounter bugs that were not present in previous versions of Tabula. If you have any issues with this beta version of Tabula, please let us know!

New features / bugfixes

  • Tabula now extracts tables up to 7x faster than previous versions.
  • Table auto-detection has also been improved. (#456, tabulapdf/tabula-java#56)
  • If there’s an error during file upload & initial processing, warn the user. (#433)
  • Lots and lots of other improvements — the extraction and processing backend has been completely rewritten!

Known Issues & Caveats

  • Bug: This version of Tabula always shows that there is an update, even for the same version: "New version! Tabula 1.1.0-beta.1 is available (you have 1.1.0-beta1)".
  • Bug: Although the backend for the Tabula app has been rewritten using tabula-java instead of tabula-extractor, the "script" export option still generates commands to call the older tabula-extractor. To fix this, you may follow the download and example instructions for tabula-java, and replace the tabula command with java -jar tabula-0.9.0-jar-with-dependencies.jar in the generated script. (#484)
  • Caveat: Tabula only works on text-based PDFs (ones where you can select text). Scanned documents do not work, and we do not recommend OCR for large files unless you have a data cleaning plan since even state-of-the-art OCR software can have significant error rates.
  • _OS X Gatekeeper_: If you’re running Mac OS X 10.8 or later and get a message that says "Tabula can't be opened because it is from an unidentified developer" message, please let us know. (It shouldn't be happening anymore.) See this GateKeeper page for more assistance — your "Allow applications downloaded from" setting should be set to "Mac App Store and identified developers" or "Anywhere."
