# Announcing FusionAuth Version 1.54.0

Version 1.54.0 of FusionAuth fixes an important SCIM issue.

We recently announced the release of FusionAuth version `1.54.0` into the world. Our astute audience of developers will probably notice that this release looks a little different than most, so let's talk about it.

As is common in the software world, most minor releases include the addition of a notable, customer-facing feature:

*   [1.53.0](/blog/announcing-fusionauth-1-53) added webhook logs and new updates for login lambdas. 
*   [1.52.0](/blog/announcing-fusionauth-1-52) gave passkeys to the Community plan. 
*   [1.51.0](/blog/announcing-fusionauth-1-51) made major changes to theming.

`1.54.0` takes a slight turn. There are still two significant updates to this release. Although we know that the individual audiences for each will be limited, they represent a big change to the FusionAuth software, so they still warrant a version update.

Long-time users of FusionAuth will remember that we released SCIM support way back in [1.36.0](/blog/announcing-fusionauth-1-36). We've been pleased to see how many of you have put SCIM to work, but there was a nagging problem that we needed to address. The most recent release adds a change to the SCIM groups API that resolves a situation which could cause concurrency issues when making simultaneous calls to patch groups and group members. This revision ensures SCIM group updates all show up when and how they should.

On top of the SCIM changes, we've also mitigated one security vulnerability and improved overall stability. You can catch all of the details in the [release notes](/docs/release-notes). We expect to release `1.55.0` within the next few weeks, and it has some great additions that we're excited to share.
