Apache Tika 1.21
The most notable changes in Tika 1.21 over the previous release are:
- Add optional AUTO mode to OCR'ing of PDFs. If tesseract is installed and on the path, and this option is selected programmatically or via TikaConfig(), the PDFParser will use heuristics to decide whether or not to run OCR per page on PDFs. (TIKA-2749)
- The ZipContainerDetector's default behavior was changed to run streaming detection up to its markLimit. Users can get the legacy behavior (spool-to-file/rely-on-underlying-file-in-TikaInputStream)
- The POIFSContainerDetector requires an underlying file; it will try to spool the file to disk; if the file's length is > markLimit, it will not attempt detection; set markLimit to -1 for legacy behavior (TIKA-2849).
- Upgrade PDFBox to 2.0.14 (TIKA-2834).
- Add CSV detection and replace TXTParser with TextAndCSVParser; users can turn off CSV detection by excluding the TextAndCSVParser and adding back the TXTParser via tika-config (TIKA-2833).
- Add a CSVParser. CSV detection is currently based solely on filename and/or information conveyed via Metadata (TIKA-2826).
- General upgrades: asm, bouncycastle, commons-codec, commons-lang3, cxf, guava, h2, httpcomponents, jackcess, junrar, Lucene, mime4j, opennlp, parso,sqlite-jdbc (provided), zstd-jni (provided) (TIKA-2824)
- Bundle xerces2 with tika-parsers (TIKA-2802).
- Upgrade jaxb to 2.3.2 (TIKA-2819).
- Upgrade jackson to 2.9.8 (TIKA-2717).
- Update tika-eval's common tokens lists (TIKA-2822).
- Handle bad tags in tika-eval more robustly (TIKA-2810).
- Add reports for tags in tika-eval (TIKA-2809).
- Extract text from SDT element within textboxes in .docx files (TIKA-2807).
