+description: OpenTofu 1.11.0 introduces ephemeral values and a new way to conditionally enable resources.
+---
+
+Today we've released OpenTofu v1.11.0, collecting together several months of work from the OpenTofu community, including some significant new features.
+
+## Ephemeral resources and write-only attributes
+
+**Ephemeral values** allow OpenTofu to work with data and resources that exist only in memory during a single OpenTofu phase, guaranteeing that those values will not be persisted in state snapshots or plan files:
+
+- Use [ephemeral resources](https://opentofu.org/docs/language/ephemerality/ephemeral-resources/) to request temporary access to stored credentials or network tunnels for use in provider or provisioner configurations, without the resulting values being saved in OpenTofu plan files or state snapshots.
+
+    For example, you could use an ephemeral resource to request time-limited AWS credentials from [OpenBao](https://openbao.org/) and provide them to the `hashicorp/aws` provider, or to open a temporary SSH tunnel so that the `cyrilgdn/postgresql` provider can access a Postgres server on a remote network.
+
+- Use [write-only attributes](https://opentofu.org/docs/language/ephemerality/write-only-attributes/) to set resource arguments that OpenTofu needs access to only when they are changing, such as the initial administrator password for a database. 
+
+    For example, you could use an ephemeral resource to generate an SSH keypair and then save the private key in your secret store using a write-only attribute so that OpenTofu itself will not need to retain its own copy of the key material.
+
+For more information on these and other related OpenTofu language features, refer to [Ephemerality](https://opentofu.org/docs/language/ephemerality/).
+
+## `enabled` for resources and modules
+
+OpenTofu has traditionally allowed a module to dynamically enable or disable a particular module by using [the `count` meta-argument](https://opentofu.org/docs/v1.11/language/meta-arguments/count/) to choose between either zero or one instances of the object.
+
+OpenTofu v1.11.0 introduces the `enabled` meta-argument, which we hope will make it easier for readers to understand that only zero or one instances of a resource are possible:
+
+```hcl
+variable "subnet" {
+  type = object({
+    id = string
+  })
+  default = null
+}
+
+variable "enable_cluster" {
+  type    = bool
+  default = false
+}
+
+resource "aws_subnet" "example" {
+  # ...
+
+  lifecycle {
+    enabled = var.subnet == null
+  }
+}
+
+resource "aws_instance" "example" {
+  # ...
+  subnet_id = var.subnet != null ? var.subnet.id : aws_subnet.example.id
+  # ...
+}
+
+module "servers" {
+  source = "./app-cluster"
+  servers = 5
+  lifecycle {
+    enabled = var.enable_cluster
+  }
+}
+```
+
+For more information, refer to [The `enabled` meta-argument](https://opentofu.org/docs/language/meta-arguments/enabled/).
+
+## Various other improvements
+
+There are numerous other improvements in OpenTofu v1.11. For more information, refer to [What's new in version v1.11](https://opentofu.org/docs/intro/whats-new/), or to [the OpenTofu v1.11.0 release notes](https://github.com/opentofu/opentofu/releases/tag/v1.11.0).
