*Dear colleagues, We are happy to announce that we have released the second version of the South Slavic CLASSLA-web corpora. **The corpus collection contains approximately 38 million texts and 17 billion words, collected from the web in 2024, and covers the full South Slavic language group: Bosnian, Bulgarian, Croatian, Macedonian, Montenegrin, Serbian, and Slovenian. Compared to CLASSLA-web 1.0, the new web corpora are significantly expanded and largely consist of new texts. The corpora are linguistically annotated, automatically classified by genre and enriched with topic labels.**The web corpus collection is intended for a wide range of uses, including corpus linguistics, lexicography, and other linguistic research, as well as for natural language processing tasks such as training and evaluating language models, and creating genre- or topic-specific datasets.***
***A detailed description of the resource can be found in the accompanying paper (https://doi.org/10.48550/arXiv.2601.11170). **Further information on both CLASSLA-web 1.0 and 2.0 versions, including details on corpus construction, additional resources, a video describing the workflow, and citation guidelines, is available on the CLASSLA-web website: https://clarinsi.github.io/classla-web/ **If you are interested in language resources and technologies for South Slavic languages, we invite you to browse the CLASSLA-web corpora via the CLARIN.SI concordancers (**https://www.clarin.si/ske/#open**) or download them **under a CC0 license **from the CLARIN.SI repository: http://hdl.handle.net/11356/2079* *Best wishes, CLASSLA-web authors: Taja Kuzman Pungeršek, Peter Rupnik, Vít Suchomel and Nikola Ljubešić, supported by CLARIN.SI https://www.clarin.si/info/about/ and CLASSLA https://www.clarin.si/info/k-centre/*
