Bharath,

=20

The best advice I can give is to look at the upcoming NEWS items

=20

https://gitea.osgeo.org/postgis/postgis/src/branch/stable-3.6/NEWS

=20

and yes we most likely will do a micro release before February 28

Subject: Inquiry on planned PostGIS releases and minor-version behavior =
(now=E2=80=93Feb 28)

Hello PostGIS Team,

I=E2=80=99m a PostgreSQL Database Engineer managing production =
PostgreSQL/PostGIS workloads on AWS RDS/Aurora.

We are planning a PostgreSQL minor upgrade (PostgreSQL 16.6 =E2=86=92 =
16.11) in the near term. In our environment, past PostGIS minor/patch =
releases have occasionally caused operational issues due to changes in =
function behavior, even when PostgreSQL itself was a minor upgrade. =
Because AWS may bundle a newer PostGIS minor version along with a =
PostgreSQL minor upgrade, we want to plan and execute testing and =
production rollout as close together as possible.

To help us plan safely, I wanted to ask:

1.	Are there any planned PostGIS releases (minor or patch) between now =
and February 28?

*	If yes, which versions are anticipated?
*	If not, when is the next postgis version release anticipated?

2.	For PostGIS minor/patch releases (e.g., 3.6.x =E2=86=92 3.6.y):

*	Are changes strictly bug fixes, or can they include behavioral changes =
to existing functions?
*	Are there specific classes of functions (geometry processing, =
topology, raster, etc.) where behavior changes are more likely?

3.	Release notes & compatibility guidance:

*	Is there a recommended way to identify function-level behavior changes =
between minor versions (beyond high-level release notes)?
*	Are there guarantees or best-practice guidance around backward =
compatibility expectations for PostGIS patch releases?

4.	Operational best practices:

*	Do you recommend pinning PostGIS patch versions in production where =
possible, or validating only specific functions we rely on most during =
upgrades?

Any guidance you can share will help us reduce risk and plan upgrades =
more confidently.

Thank you for your time and for all the work you do on PostGIS.

Best regards,
Bharath
PostgreSQL Database Engineer
