CHANGES IN udpipe VERSION 0.8.9

• fix R CMD check message on Fedora clang infrastructure: rcpp_udpipe.cpp:243:8: warning: use of bitwise ‘&’ with boolean operands

CHANGES IN udpipe VERSION 0.8.8

• dtm_svd_similarity, fix to make sure that if provided a dtm with features which are all missing/zero, the scoring still works as expected instead of removing features which contain no data whatsoever. So that dtm_svd_similarity can be used alongside embeddings of R package word2vec which might contain words which are not in the dtm. See the example in ?dtm_svd_similarity
• added txt_grepl
• dtm_align now uses NCOL to see if y is a vector instead of a data.frame

CHANGES IN udpipe VERSION 0.8.7

CHANGES IN udpipe VERSION 0.8.6

• Downloading models to paths containing non-ASCII characters now works (issue #95)

• Added txt_paste
• Added txt_context
• Use html_vignette instead of html_document in the vignettes in order to reduce package size

• Added groups argument to dtm_colsums and dtm_rowsums
• Added dtm_align

• txt_collapse now also works if provided a list of character vectors
• paste.data.frame now works as well if a data.table is passed instead of a data.frame

CHANGES IN udpipe VERSION 0.8.4-1

• Fixing the Solaris compilation issue in ufal::udpipe::multiword_splitter::append_token

CHANGES IN udpipe VERSION 0.8.4

• Update to UDPipe 1.2.1 (28 Sep 2018)
  • this adds segment_size and learning_rate_final parameters to tokenizer training

CHANGES IN udpipe VERSION 0.8.3

• Default of udpipe_download_model is now changed, downloads now models built on Universal Dependencies 2.4 instead of the models build on Universal Dependencies 2.3

• fix issue in udpipe_reconstruct giving wrong values in start/end positions of the token in case someone had as well SpacesBefore as SpacesAfter for a token. For users prior to version 0.8.3 you can easily circumvent this issue by removing leading/trailing white space in your text by using trimws on your text before using udpipe::udpipe.
