# Deprecated functionality
Deprecated features are features that iotagent-node-lib stills support but that are not maintained or evolved any
longer. In particular:
- Bugs or issues related with deprecated features and not affecting any other feature are not addressed (they are
closed in github.com as soon as they are spotted).
- Documentation on deprecated features is removed from the repository documentation. Documentation is still available
in the documentation set associated to older versions (in the repository release branches).
- Deprecated functionality is eventually removed from iotagent-node-lib. Thus you are strongly encouraged to change
your implementations using iotagent-node-lib in order not rely on deprecated functionality.
A list of deprecated features and the version in which they were deprecated follows:
- Support to NGSI v1 (finally removed in 2.18.0)
- Support to Node.js v4 in iotagent-node-lib 2.8.1 (finally removed in 2.9.0)
- Support to Node.js v6 in iotagent-node-lib 2.9.0 (finally removed in 2.10.0)
- Support to Node.js v8 in iotagent-node-lib 2.12.0 (finally removed in 2.13.0)
- Support to Node.js v10 in iotagent-node-lib 2.15.0 (finally removed in 2.16.0)
- Support to Node.js v12 in iotagent-node-lib 2.24.0 (finally removed in 2.25.0)
- Support to NGSI-LD v1.3 in iotagent-node-lib 2.25.0 (finally removed in 2.26.0)
- Support groups (provision) statically defined by configuration
- Support to in-memory registry (i.e.`deviceRegistry.type=memory`)
- eventType configuration (finally removed in 3.0.0)
- Support to legacy expressions (finally removed in 3.2.0)
- Bidirectinal pluging (finally removed in 3.4.0)
- appendMode configuration (`IOTA_APPEND_MODE` env var) (finally removed in 3.4.0)
- `config.stats` section, and push-mode statistics.
- Services API routes (`/iot/services`) in favor of the `/iot/groups`. Both are still supported, but the former is
deprecated.
The use of Node.js v14 is highly recommended.
## Using old iotagent-node-lib versions
Although you are encouraged to use always the newest iotagent-node-lib version, take into account the following
information in the case you want to use old versions:
- Code corresponding to old releases is available at the
[iotagent-node-lib GitHub repository](https://github.com/telefonicaid/iotagent-node-lib). Each release number (e.g.
2.7.0 ) has associated the following: _ A tag, e.g. `2.7.0`. It points to the base version. _ A release branch,
`release/2.7.0`. The HEAD of this branch usually matches the aforementioned tag. However, if some hotfixes were
developed on the base version, this branch contains such hotfixes.
- Documentation corresponding to old versions can be found at
[readthedocs.io](https://iotagent-node-lib.readthedocs.io). Use the panel in the right bottom corner to navigate to
the right version.
