## 1 Erl_interface Release Notes

This document describes the changes made to the Erl_interface application.

  Own Id: OTP-5295 Aux Id: OTP-5387

### 1.2 Erl_interface 3.5

#### 1.2.1 Improvements and New Features

- Process identifiers and port identifiers have been made more unique. Previously 18 bits were used as id in the internal representation of process and port identifiers. Now 28 bits are used.
  The maximum limit on the number of concurrently existing processes due to the representation of pids has been increased to 268435456 processes. The same is true for ports. This limit will at least on a 32-bit architecture be impossible to reach due to memory shortage.
  NOTE: By default, the `ERTS`, and the `erl_interface`, `ei`, and `jinterface` libraries are now only guaranteed to be compatible with other Erlang/OTP components from the same release. It is possible to set each component in compatibility mode of an earlier release, though. See the documentation for respective component on how to set it in compatibility mode.
