# 1 SASL Release Notes

This document describes the changes made to the SASL application.

### 1.1 SASL 2.1.9.3

#### Improvements and New Features

- Honor start type in .rel files when building relup files

  Previously, relup file always included an application:start(Application, permanent) apply instruction for every application that appear in the UpTo/DowFrom release file, whatever their start type in the release file.

  The new implementation fixes this bug by honoring the start type according to the rel(5) format. If the start type is none, no apply line is included in the relup. If the start type is load, the relup includes instruction to only load the application. Otherwise, the relup includes an instruction to start the application to the according type.

  The fix is implemented by adding a new parameter to the add_application high level appup instruction. This new parameter is documented in appup(5).

### 1.2 SASL 2.1.9.2

#### Fixed Bugs and Malfunctions

- In R13B04 sys:get_status was modified to invoke format_status/2 in the callback module if the module exports that function. This resulted in a change to the term returned from calling sys:get_status on the supervisor module, since supervisor is a gen_server and gen_server exports format_status. The sasl release_handler_1 module had a dependency on the pre-R13B04 term returned by sys:get_status when invoked on a supervisor, so the R13B04 change broke that dependency.

  This problem has been fixed by change release_handler_1 to handle both the pre-R13B04 and R13B04 terms that sys:get_status can return from a supervisor.

### 1.4 SASL 2.1.9

#### Improvements and New Features

- The re:grep/1 function now uses the 're' module instead of the deprecated 'regexp' module. There are new functions rb:filter/1 and rb:filter/2 for easier filtering of reports. (Thanks to Alvaro Videla.)

  Own Id: OTP-8443

- There is new function sasl_report:format_report/3 that works like the existing sasl_report:write_report/3 function except that it returns a formatted string. Note that there is currently no documentation for the sasl_report module. (Thanks to Jay Nelson.)

  Own Id: OTP-8445

- Cleanups suggested by tidier and modernization of types and specs.

### 1.5 SASL 2.1.8

#### Improvements and New Features

- The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.

### 1.6 SASL 2.1.7

#### Improvements and New Features

- The Windows utility Erlsrv, run in interactive mode now accepts options for registering internal service name and description field of Windows registry database.

  Own Id: OTP-8132

### 1.7 SASL 2.1.6

#### Fixed Bugs and Malfunctions

- When using the SASL application configuration parameter masters the error tuple {error,{no_such_file,{Master,FileName}}} was sometimes returned even though the file FileName existed.

### 1.12 SASL 2.1.5

#### Fixed Bugs and Malfunctions

- Removed some dead code from erlsrv:get_service/2, release_handler:do_write_file/2, systools_relup:foreach_baserel_up/7 and systools_relup:foreach_baserel_dn/7.

  Own Id: OTP-6499

### 1.13 SASL 2.1.4

#### Improvements and New Features

- Added an option {outdir,Dir} to the functions in systools, making it possible to specify in which directory a boot script, relup file or release package file should be placed.

  Also, when using systools:make_tar/2 to create a release package file, the boot script, relup file and sys.config are now searched for also in the current working directory and any directory specified by the path option, not only in the directory of the .rel file.

  As part of the work some minor bugs have been corrected:

  - systools:make_script/1,2 now returns error if the .script and/or .boot file could not be opened for writing, not ok.

  - systools:make_tar/1,2 can now handle a RelName argument which includes a path. Previously this would cause the .rel file to end up in the wrong directory in the resulting tar file.

  - A documentation error for systools:make_tar/1,2: The .rel file is placed in the releases directory in the tar file, not releases/RelVsn.

### 1.14 SASL 2.1.3

#### Fixed Bugs and Malfunctions

- release_handler:upgrade_app/2 and release_handler:downgrade_app/2,3 -- used for testing application upgrade and downgrade according to the .appup file -- now update application configuration parameters correctly. (Thanks to Serge Aleynikov)

  Own Id: OTP-6039

### 1.16 SASL 2.1.1

#### Improvements and New Features

- Added a number of functions to release_handler which makes it possible to test upgrade and downgrade of applications according to an .appup file "on the fly":
  - upgrade_app/2
  - upgrade_script/2
  - downgrade_app/2,3
  - downgrade_script/3
  - eval_appup_script/4

  Own Id: OTP-5858

### 1.17 SASL 2.1

#### Improvements and New Features

- A new option {update_paths,Bool} has been added for release_handler:install_release/2. It indicates if all application code paths should be updated (Bool==true), or if only code paths for modified applications should be updated (Bool==false, default).

  release_handler:set_unpacked/2 now returns an error tuple if a specified application directory does not exist.

  *** POTENTIAL INCOMPATIBILITY ***

### 1.18 SASL 2.0.1

#### Improvements and New Features
