CHANGES IN udpipe VERSION 0.8.11

• replace move with std::move to fix R CMD check warning on recent versions of clang compilers

CHANGES IN udpipe VERSION 0.8.10

• use snprintf instead of sprintf to handle the R CMD check deprecating note on M1mac

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

• txt_count now always returns an integer, even if in the border case where a character vector of length 0 is supplied

CHANGES IN udpipe VERSION 0.8.6

• Downloading models to paths containing non-ASCII characters now works (issue #95)
• strsplit.data.frame gains … which are passed on to strsplit (e.g. to use fixed=TRUE for speeding up)
• read_connlu is now using fixed=TRUE when splitting by newline symbol (for speeding up parsing with function udpipe)
• Added txt_paste
• Added txt_context
• Use html_vignette instead of html_document in the vignettes in order to reduce package size

CHANGES IN udpipe VERSION 0.8.5

• paste.data.frame now works as well if a data.table is passed instead of a data.frame
• txt_recode gains an extra argument na.rm

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
  • correctly set SpaceAfter for last token when normalizing spaces.

• Added dtm_chisq
• Added dtm_svd_similarity
• Added as_fasttext

• Experimental changes regarding cbind_dependencies which might change in a subsequent release.
  • cbind_dependencies now has been implementend for type ‘child’.
  • cbind_dependencies now allows to add row numbers of the parent or children where the token is linked to using the dependency parsing output.

• in case the model loaded with udpipe_load_model is a nil pointer (most likely due to users which restarted their R sessions without knowing), try reloading the model file in udpipe_annotate
• 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.
