IVM Development Group is pleased to announce the release of [pg_ivm 1.14]( https://github.com/sraoss/pg_ivm/releases/tag/v1.14 ).

Changes since the v1.13 release include:

## What's Changed

### Bug Fixes

* Fix a bug in the maintenance of outer join views that include cross 
joins (Yugo Nagata)

     When an outer join view has a cross join in its children, 
incremental maintenance could not be performed properly.

* Fix a bug in the maintenance of outer join views with NULLs in 
join-condition columns (Yugo Nagata)

     When an outer join view contains NULLs in join-condition columns, 
incremental maintenance could not be performed correctly.

### About pg_ivm

pg_ivm is an extension module that provides Incremental View Maintenance 
(IVM) feature.

Incremental View Maintenance (IVM) is a way to make materialized views 
up-to-date in
which only incremental changes are computed and applied on views rather 
than recomputing.
pg_ivm provides a kind of immediate maintenance, in which materialized 
views are updated
immediately after a base table is modified.
