4.0.0

let g:AutoPairsVersion = 40000

Changed

Added docs for <CR> incompatibilities
Documentation with some basic how-to guides for auto-pairs features. These can technically be figured out by just reading the documentation, but it's easier to compress it into concrete guides.
Documentation for Krasjet's space-only completion exceptions, and first-class support for it.
Documentation and first-class support for Krasjet's balance blacklist

Minimum Vim version is now correctly listed as 8.1 patch 1114; I severely misread the minimum required version before.
Missing ... specifier prevented argument forwarding for IgnoreInsertEnter
Missing period for string concatenation seems to have broken the move feature
Switched to a variable for universal event ignoring, without overwriting the variable unrecoverably (exists('##InsertLeavePre') <3)
[parallel-fixed in an unversioned 3.0.x-version] Fixed bad regex management for multibyte pairs (#71)

Tests for both the character whitelist for only completing on space, and the balance check blacklist.
Added g:AutoPairsAutoBreakBefore and g:AutoPairsSyncAutoBreakOptions (#57)
InsertLeavePre is now ignored
Regex pairs are now disabled and made opt-in only (#53)
g:AutoPairsPrefix, used for switching the default prefix in incompatible map mode.
The LaTeX pairs \[\] and \(\) are supported out of the box for the tex filetype
Breaking: regex is now disabled by default, and requires a manual parameter. See :h autopairs-pair-object.
The auto-pairs compatible maps prefix can now be adjusted with g:AutoPairsPrefix (#48, #70)
