• Prevented from duplicated file names which resulted in duplicated bibliography entries in the add-in (@GegznaV, #67, #68)
• Argument encoding = getOption("citr.encoding") is passed to readLines() in insert_citation() (@GegznaV, #68)

• Fixed bug related to use of absolute file paths that caused errors finding the bibliography files (reported by @bblodfon and @neurotroph, #52)

• Improves tidy_bib_file()-search for reference handles (reported by @Robinlovelace, #48, and @heinonmatti, #49)
• Addin now correctly uses absolute rather than relative paths to update reference files

• New function tidy_bib_file() removes duplicate and unneeded entries from a Bib(La)Tex-file.
• Added encoding option to functions that read Bib(La)TeX-files and a corresponding global option. (reported by @sammo3182 #11)
• Error message in insert_citation() are printed to the dialog instead of the console (reported by @sammo3182 #11)
• RStudio addin
  • Access to Zotero group libraries (#9)
  • New settings tab

• Zotero/Juris-M library can now be accessed directly via the Better BibTeX extension (https://github.com/retorquere/zotero-better-bibtex). The document's bibliography file is updated accordingly. See ?insert_citation.
• bibliography entries are no longer checked for missing fields (suggested by @awmercer, #8)
• If the current document is a child (i.e., included in a larger R Markdown document) the parent file is searched for bibliography paths (suggested and contributed to by @yihui, #7, #10)
• References in addin selection and inserted markdown citations are ordered alphabetically

Initial release.
