 A bug in the logic for incorporating includes as absolute paths in tracked "read" files has been fixed.
 
+#### OpenTofu file extensions handled in catalog and scaffold
+
+Terragrunt `catalog` now lists modules that use `.tofu`, `.tf.json`, or `.tofu.json` files. Terragrunt `scaffold` now parses variables from `.tofu` files — previously, variables defined in `.tofu` files were silently missing from the generated `terragrunt.hcl`.
+
+#### Bootstrap `use_lockfile` boolean handling fixed
+
+A bug in remote state backend configuration caused `use_lockfile = true` to be emitted as `use_lockfile = "true"` (quoted string), which OpenTofu/Terraform rejects. Boolean values in backend config are now normalized correctly.
+
+#### Provider cache lock file corruption fixed
+
+A bug that could cause provider cache lock file corruption has been fixed.
+
+#### Git filter discovery for `read_terragrunt_config` fixed
+
+Git-filter discovery now correctly detects stacks affected by changes to sidecar files read via `read_terragrunt_config()`, by parsing stack files to check `FilesRead` against diff paths instead of relying on generic directory-based detection.
+
+#### S3 bucket tagging moved to bucket creation
+
+S3 bucket tagging during backend bootstrapping has been moved to bucket creation. This prevents errors caused when SCPs restrict creation of buckets without appropriate tags.
+
+#### Windows user input fixed
+
+A bug on Windows caused user input prompts (e.g. for confirming `apply`) to stop working after subprocess execution. Terragrunt now saves and restores console state around every subprocess execution and re-enables Virtual Terminal processing.
+
+#### Authentication during queue construction fixed
+
+A bug in the logic for parsing configurations during discovery for use-cases like `--filter 'reading=*'` where configurations need to be parsed to determine whether or not they end up in the final run queue has been fixed. Configurations will now properly call any configured `--auth-provider-cmd` authenticator before parsing configurations, preventing errors for HCL functions like `sops_decrypt_file` that require authentication before parsing can proceed.
+
+#### `hcl fmt` on unintended files during scaffold fixed
+
+A bug caused `hcl fmt` to run on files that weren't generated by `scaffold`. Formatting is now scoped to only scaffolded content.
+
+#### Input precision loss fixed
+
+A bug in the way Terragrunt handled setting of OpenTofu/Terraform inputs from numbers resulted in precision loss. That bug has been fixed.
