Postiz vs Umbraco CMS: at a glance
What is Postiz?
Postiz encrypts channel tokens and lets agents hand out channel-connect links
The 13 November release adds opt-in encryption of channel tokens at rest (local key or AWS KMS), connect links that let the public API or an MCP agent send someone a link to add a channel, Amazon SES for email and 20-item Instagram carousels with alt text. It also closes two access-control holes: plain members could call billing routes, and post saves could carry another organization's ids. October's release added preview comments and a self-hosted MCP connector.
What is Umbraco CMS?
Umbraco 19 reaches its first release candidate on .NET 11 GA.
Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.

Postiz encrypts channel tokens and lets agents hand out channel-connect links
◆ Current state
The 13 November release adds opt-in encryption of channel tokens at rest (local key or AWS KMS), connect links that let the public API or an MCP agent send someone a link to add a channel, Amazon SES for email and 20-item Instagram carousels with alt text. It also closes two access-control holes: plain members could call billing routes, and post saves could carry another organization's ids. October's release added preview comments and a self-hosted MCP connector.
◆ Where it's heading
Security and agent access now ship together. Each release hardens the self-hosted install while giving MCP agents and the API more of the workflow, from preview links in October to onboarding a client's channel in November.
◆ Prediction
Expect more MCP and API actions around client onboarding and review, and further access-control audits given two fixes in this release alone.
Umbraco CMS
6.3MARKETING
Umbraco 19 reaches its first release candidate on .NET 11 GA.
◆ Current state
Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.
◆ Where it's heading
The 19 cycle is moving quickly from beta to candidate, and rc1 is about hardening rather than new editor features: dependencies on GA, environment-level permissions and load-balancing performance. The 17 and 18 lines are kept in step on security fixes while 19 matures.
◆ Prediction
Expect 18.3 and 17.8 to go stable, followed by further 19 release candidates and a 19.0.0 stable release built on .NET 11.
