 ### Fixed
 
-- Plain NOW export now opens ZIP input with `java.util.zip.ZipFile` in streaming mode instead of Apache Commons `ZipFile`, removing the multi-minute startup delay on very large archives with huge entry counts and allowing extraction to begin almost immediately
-- Plain NOW export startup and progress diagnostics now log ZIP open time and first-output timing more explicitly, making it easier to distinguish ZIP indexing overhead from actual extraction work
-- Plain Word2Vec export now uses the same archive-order streaming ZIP path as plain NOW output, including the faster `java.util.zip.ZipFile` opener for large archives with many entries
-- Plain CoNLL-U export now also uses the archive-order streaming ZIP path when exactly one base ZIP is given, while multi-ZIP and foundry-paired CoNLL-U input stays on the ordered pipeline
-- CoreNLP now uses the the base tokenization and sentence boundaries instead of its own, preventing morpho/constituency drifts (#38).
+- Plain text output modes now use the faster archive-order streaming ZIP path with `java.util.zip.ZipFile`: `NOW`, `Word2Vec`, and `CoNLL-U` when exactly one base ZIP is given. This removes the multi-minute startup delay on very large archives with huge entry counts, while multi-ZIP and foundry-paired `CoNLL-U` input stays on the ordered pipeline
+- Streaming text-output diagnostics now log ZIP open time and first-output timing more explicitly, making it easier to distinguish ZIP indexing overhead from actual extraction work
+- CoreNLP now uses the base tokenization and sentence boundaries instead of its own, preventing morpho/constituency drift on forms such as `Schüler:innen` ([#38](https://github.com/KorAP/korapxmltool/issues/38))
