elastic v0.8.4

NEW FEATURES

• Gains new function docs_bulk_update() to do bulk updates to documents (#169)

MINOR IMPROVEMENTS

• Vignettes weren't showing up on CRAN, fixed (#205)
• Added an example of using WKT in a query (#215)
• using markdown docs (#209)
• id is now optional in docs_create() - if you don't pass a document identifier Elasticsearch generates one for you (#216) thanks @jbrant
• docs_bulk() gains new parameter quiet to optionally turn off the progress bar (#202)

BUG FIXES

• Fix to docs_bulk() for encoding in different locales (#223) (#224) thanks @Lchiffon
• Fix for index_get(): you can now only pass in one value to the features parameter (one of settings, mappings, or aliases) (#218) thanks @happyshows
• Fix to index_create() to handle a list body, in addition to a JSON body (#214) thanks @emillykkejensen
• Fix to docs_bulk() for document IDs as factors (#212) thanks @AMR-KELEG
• Temporary files created when using docs_bulk() (and taking up disk space) are cleaned up now (deleted), though if you pass in your own file paths you have to clean them up (#208) thanks @emillykkejensen
