## 1 Erl_interface Release Notes

This document describes the changes made to the Erl_interface application.

### 1.1 Erl_Interface 3.5.5.4

#### 1.1.1 Fixed Bugs and Malfunctions

- The symbol __erl_errno was undefined in the single thread version of the ei library, but is now defined.
  Own Id: OTP-6887
- Corrected FreeBSD build error.
  Own Id: OTP-7093

### 1.2 Erl_Interface 3.5.5.3

#### 1.2.1 Improvements and New Features

- Calls to alloca in erl_marshal.c have been removed. A static buffer is now used instead to store node names temporarily.
  Own Id: OTP-6331 Aux Id: seq10468
- ei_print_term interprets a list of integers with values from 0 to 255 as a string. If the original list contains the integer 0, this is considered terminator of the string. This is incorrect. The function has now been modified to not look for '\0' in a string, but always print all characters.
  Own Id: OTP-6339 Aux Id: seq10492

### 1.3 Erl_Interface 3.5.5.2

#### 1.3.1 Fixed Bugs and Malfunctions

- The combination of xeon processors with 64bit x86 extensions and a 32bit linux could cause ei_decode_long and ei_decode_longlong to fail for the value LONG_MIN and LONGLONG_MIN. The conversion is now made more portable.
  Own Id: OTP-6216

### 1.4 Erl_Interface 3.5.5.1

#### 1.4.1 Improvements and New Features

- Portability enchancements.
  Own Id: OTP-6132

### 1.5 Erl_Interface 3.5.5

#### 1.5.1 Fixed Bugs and Malfunctions

- Different (and old) config.guess files in the erts and erl_interface applications would cause build problems on the new Intel-based iMacs. (Thanks to Sebastion Strollo.)
  Own Id: OTP-5967
- pthread header and library mismatch on linux systems (at least some SuSE and Debian) with both NPTL and Linuxthreads libraries installed.
  Own Id: OTP-5981

#### 1.5.2 Improvements and New Features

- Support for a C node to connect to an Erlang node on a standalone host has been added.
  Own Id: OTP-5883 Aux Id: seq10170

### 1.6 Erl_interface 3.5.2

#### 1.6.1 Improvements and New Features

- A configuration test error caused erl_interface to be built without support for threads. This has been corrected.
  Own Id: OTP-5456

### 1.7 Erl_interface 3.5.1

#### 1.7.1 Improvements and New Features

- Changes and improvements have been made to the build and test environment to solve problems with failing erl_interface test cases.
  Own Id: OTP-5295 Aux Id: OTP-5387

### 1.8 Erl_interface 3.5

#### 1.8.1 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.
  *** POTENTIAL INCOMPATIBILITY ***
