 You can find a list of release notes for Chainlink nodes in the [smartcontractkit GitHub repository](https://github.com/smartcontractkit/chainlink/releases). Docker images are available in the [Chainlink Docker hub](https://hub.docker.com/r/smartcontract/chainlink/tags).

+## Changes in v1.9.0 nodes
+
+**[v1.9.0 release notes](https://github.com/smartcontractkit/chainlink/releases/tag/v1.9.0)**
+
+- Added the [`length` task](/docs/jobs/task-types/length/) and the [`lessthan` task](/docs/jobs/task-types/lessthan/) for jobs.
+- Added the `gasUnlimited` parameter to the [`ethcall` task](/docs/jobs/task-types/eth-call/).
+- The **Keys** page in Operator UI includes several admin commands that were previously available only by using the `keys eth chain` commands:
+  - Ability to abandon all current transactions: This is the same as the `abandon` CLI command. Previously it was necessary to edit the database directly to abandon transactions. This command makes it easier to resolve issues that require transactions to be abandoned.
+  - Ability to enable/disable a key for a specific chain: This allows you to control keys on a per-chain basis.
+  - Ability to manually set the nonce for a key. This gives you a way to set the next nonce for a specific key in the UI, which can be useful for debugging.
+
+## Changes in v1.8.1 nodes
+
+**[v1.8.1 release notes](https://github.com/smartcontractkit/chainlink/releases/tag/v1.8.1)**
+
+- Added several improvements for Arbitrum Nitro including a multi-dimensional gas model, with dynamic gas pricing and limits.
+  - The new default estimator for Arbitrum networks uses the suggested gas price up to `ETH_MAX_GAS_PRICE_WEI` with a 1000 gwei default value and an estimated gas limit up to `ETH_GAS_LIMIT_MAX` with a 1,000,000,000 default.
+  - Remove the `GAS_ESTIMATOR_MODE` environment variable to use the new defaults.
+- `ETH_GAS_LIMIT_MAX` to puts a maximum on the gas limit returned by the Arbitrum estimator.

+- `input`: Byte array, or string to get the length for.
+
+**Outputs**
+
+The length of the byte array or string.
+
+**Note**: For strings containing multi-byte unicode characters, the output is the length in bytes and not number of characters.
+
+**Example**
+
+```jpv2

+```
+
+Given the input string "xyz", the task will return 3, length of the string.
