0.2.7

• Add support for TextDocumentSyncKind.Incremental. There is a new setting
  called g:lsc_enable_incremental_sync which is defaulted to v:false to
  allow the client to attempt incremental syncs. This feature is experimental.
• Bug Fix: Use buffer filetype rather than current filetype when flushing file
  changes for background buffers.
• Update the diagnostic under the cursor when diagnostics change for the file.
• Bug Fix: Don't change diagnostic highlights while in visual mode.
