# 1 Debugger Release Notes

This document describes the changes made to the Debugger application.

### 1.1 Debugger 3.2.8

#### Fixed Bugs and Malfunctions

- Fixed disappearing breakpoints bug, reported by Ricardo Catalinas Jiménez.

  Own Id: OTP-9950

### 1.2 Debugger 3.2.7

#### Fixed Bugs and Malfunctions

- Fix "OK" spelling in debugger messages and variables

  Simple code refactor in the debugger: renames all the occurrences of "Ok" to "OK" in the code, variable names and strings. This improves the consistency of the code and follows the GTK UI where "OK" is always used.(Thanks to Ricardo Catalinas Jiménez)

  Own Id: OTP-9699

#### Improvements and New Features

- Variables are now now allowed in 'fun M:F/A' as suggested by Richard O'Keefe in EEP-23.

  The representation of 'fun M:F/A' in the abstract format has been changed in an incompatible way. Tools that directly read or manipulate the abstract format (such as parse transforms) may need to be updated. The compiler can handle both the new and the old format (i.e. extracting the abstract format from a pre-R15 BEAM file and compiling it using compile:forms/1,2 will work). The syntax_tools application can also handle both formats.

  *** POTENTIAL INCOMPATIBILITY ***

  An escript may now set explicit arguments to the emulator, such as -smp enabled.

  An escript may now contain a precompiled beam file.

  An escript may now contain an archive file containing one or more applications (experimental).

  The internal module code_aux has been removed.

  Own Id: OTP-6944 Aux Id: OTP-6554, OTP-6911

### 1.13 Debugger 3.1.1.1

#### Improvements and New Features

- Minor Makefile changes.

  Own Id: OTP-6689

- Obsolete guard tests (such as list()) have been replaced with the modern guard tests (such as is_list()).

  Own Id: OTP-6725

### 1.14 Debugger 3.1.1

#### Fixed Bugs and Malfunctions

- Removed some dead code from dbg_ieval.

  Own Id: OTP-6552

### 1.15 Debugger 3.1

#### Fixed Bugs and Malfunctions

- The interpreter could not handle the case where an expression that should evaluate to a fun referred to uninterpreted code.

  Own Id: OTP-6061 Aux Id: seq10295

- Timeout for gen_server calls within Debugger is now set to infinity.

  Own Id: OTP-6103

#### Improvements and New Features

- Notification windows are now centered over a parent window.

  Own Id: OTP-6011 Aux Id: OTP-5987

- When interpreting a module, it is now checked that the module does not belong to the Kernel, STDLIB, GS or Debugger application, as interpreting a module used by the debugger/interpreter itself will lead to a deadlock or emulator crash.

  Also int:interpretable(Mod) has been extended to return {error,{app,App}} if Mod belongs to one of the above applications.

  Own Id: OTP-6020

- andalso/orelse is now supported.

  Own Id: OTP-6021 Aux Id: OTP-5894

### 1.16 Debugger 3.0.1

#### Fixed Bugs and Malfunctions

- When evaluating a guard expression for a fun function clause, the environment variable bindings were not taken into account.

  Own Id: OTP-5837

#### Improvements and New Features

- A number of smaller improvements to the GUI:

  - Multiple choices now possible in Function Break Dialog Window.
  - Right-clicking the Module entry in a Break Dialog Window will open a popup menu from which the appropriate (interpreted) module can be selected.
  - Auto Attach options can now be changed using the buttons in the left part of the Monitor Window, not only by the corresponding menu buttons.
  - Buttons for enabling and disabling all breakpoints have been added.
  - View Module Window keyboard shortcuts corrected.
  Own Id: OTP-4284

### 1.17 Debugger 3.0

#### Improvements and New Features

- Debugger can now handle try-catch. This meant large parts of the interpreter had to be rewritten. Also, some small changes to the GUI have been made.

  Own Id: OTP-5730

### 1.18 Debugger 2.3.3

#### Improvements and New Features

- It is now possible to encrypt the debug information in Beam files, to help keep the source code secret. See the documentation for compile on how to provide the key for encrypting, and the documentation for beam_lib on how to provide the key for decryption so that tools such as the Debugger, Xref, or Cover can be used.

  The beam_lib:chunks/2 functions now accepts an additional chunk type 'compile_info' to retrieve the compilation information directly as a term. (Thanks to Tobias Lindahl.)

  Own Id: OTP-5460 Aux Id: seq9787

#### Fixed Bugs and Malfunctions

- The graphic applications now search for HTML documentation in the correct place.
