CHANGES IN crfsuite VERSION 0.4.2

Drop C++11 specification in Makevars
Remove CITATION file
Minor cosmetic changes to remove some Pedantic compiler messages in rcpp_crfsuite.cpp and crfsuite.h
Comment out rumavl_strerror in rumavl.h as the function is not used and in order to avoid ‘warning: function declaration isn’t a prototype [-Wstrict-prototypes]’
Fix in mem_mgr of ramvl.c caused by update of valgrind 3.21.0 which is now flagging ‘realloc with size 0’ in packages
Fix memory leak when extracting the hyperparameters from the model with Trainer::params in crfsuite.hpp

CHANGES IN crfsuite VERSION 0.4.1

fixes for R CMD check warning ‘a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]’

Add option shape to txt_feature
Added coefficients.crf to allow to easily extract the coefficients from the model instead of the traditional model dump to disk
Allow to pass embedding matrix when training and predicting

Change the flexdashboard application by adding links to download the annotations

Add functionalities to allow to evaluate a model and tune hyperparameters of a crfsuite model
Expand txt_feature to allow it to get prefix/suffix of strings
Shiny app now does not show htmlOutput but textOutput + outputs extra field called ‘text_visible’ usefull if you change textOutput(“ui_txt”) to htmlOutput(“ui_txt”) in the app
ner_download_modeldata now returns an object of try-error if modeldata could not be downloaded from github. This in order to be more gracefull on CRAN machines in case of internet connectivity issues
