What is OpenTofu?

OpenTofu's v1.13 beta puts user-defined functions and types into the language for the first time.

The v1.11 series has just been closed out with a final patch, and the feed's recent history is almost entirely security work: an OCI credential leak on redirect, an init denial-of-service via crafted registry URLs, an ECH pre-shared-key leak, an arbitrary file read. Against that, v1.13.0-beta1 opens a new series with two experiments — Symbol Libraries and a -lint flag — alongside a substantial list of breaking changes.

What is Scalingo?

Scalingo phases out swap memory for application containers, shifting OOM behavior for new and restarted apps starting September 2026.

Scalingo is implementing a breaking platform change: new applications created after September 1, 2026 no longer receive swap memory, and existing applications will have their swap limit reduced to 25% of container memory on their next restart. The rest of the changelog is routine buildpack version updates across PHP, Go, Java, and Python.

OpenTofu vs Scalingo: editorial side-by-side

6.3

OpenTofu's v1.13 beta puts user-defined functions and types into the language for the first time.

◆ Current state

The v1.11 series has just been closed out with a final patch, and the feed's recent history is almost entirely security work: an OCI credential leak on redirect, an init denial-of-service via crafted registry URLs, an ECH pre-shared-key leak, an arbitrary file read. Against that, v1.13.0-beta1 opens a new series with two experiments — Symbol Libraries and a -lint flag — alongside a substantial list of breaking changes.

◆ Where it's heading

Symbol Libraries are the first release here that changes what a configuration author can express rather than what the tool does with the configuration. The beta also spends a real compatibility budget to get there: WinRM provisioner connections removed, base64gzip output changed, macOS 13 required, 32-bit builds ending. Everything else in the window — the KMS provider arguments, the OCI credential scoping, the plan-file schema embedding — is the maintenance and supply-chain hardening a fork has to do to be trusted as a drop-in.

◆ Prediction

Both new capabilities ship as experiments explicitly seeking feedback before stabilising, so the v1.13 series is likely to iterate on Symbol Library syntax and linting rules ahead of a stable release rather than adding another language feature.

DEVOPS
5.0

Scalingo phases out swap memory for application containers, shifting OOM behavior for new and restarted apps starting September 2026.

◆ Current state

Scalingo is implementing a breaking platform change: new applications created after September 1, 2026 no longer receive swap memory, and existing applications will have their swap limit reduced to 25% of container memory on their next restart. The rest of the changelog is routine buildpack version updates across PHP, Go, Java, and Python.

◆ Where it's heading

Removing swap reflects a broader PaaS trend toward tighter memory boundaries, forcing applications to be correctly sized rather than relying on disk-backed swap as an overflow buffer. For memory-inefficient applications, this will surface OOM restarts that were previously masked. Existing applications have until end of 2026 before the full cutover.

◆ Prediction

Scalingo will likely follow the swap removal with tighter memory monitoring tooling or sizing recommendations to help customers identify applications relying on swap before the end-of-2026 cutover for existing apps.
