VimTeX 2.6

It is again time for a release. There's been plenty of updates!

Note: After updating, please open some .tex file and run :VimtexClearCache ALL (see #2095 for more details on why).

Features

• Separate cite completion menu from completion match string for "smart" mode (#2095) -- this change requires users to clear the cache
• Add :VimtexClearCache command (#2095)
• Ignore *Notes.bib files from revtex* class (#2090)
• Allow to specify length of author field in menu_fmt, see :help g:vimtex_complete_bib (#2091)
• Add folding and foldtext for .bib files (#2089, #2066)
• Append to instead of overwrite latexmk's success_cmd and failure_cmd (#2088, #2085, #2079, #2076, #1237)
  • This was tricky, as it required some OS specific alternative forms. There were several PRs by @Nicholas42. Credits should also be given to @yongrenjie who helped test and find a solution that works on Windows.
• Add arXiv action to cite context menu (#2082)
• More improvements to syntax scripts
  • Support \*@ifnextchar (#2094)
  • Conceals for amssymb commands (#2068)

Fixes

• Fixed a regression on the exit callback for latexmk (#768)
• Fixed minor error in documentclass detection (#2092)
• Fixed tex2unicode substitutions (#2091)

• Allow hyphens in bib field names (#2071)
• Fixed unnecessary redraw before coming back from quickfix window (#2067, #1595)
• Fix .bib file globbing (#2035, #1658)
