IVM Development Group is pleased to announce the release of [pg_ivm 1.13]( https://github.com/sraoss/pg_ivm/releases/tag/v1.13 ).

Changes since the v1.12 release include:

### New feature

* Add support for outer joins (Yugo Nagata)

    Views that include outer joins are now supported, under the following restrictions:

    - The target list of an outer join view must include all attributes used in join conditions.
    - The target list of an outer join view cannot contain non-strict functions.
    - Only simple equijoins are supported.
    - The WHERE clause of an outer join view cannot contain non-null-rejecting predicates.
    - Aggregates are not supported in outer join views.
    - Subqueries are not supported in outer join views.

#### Acknowledgements

The development of the outer join support was sponsored by Mediapart.

### 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.
