SASL Release Notes

## 1 SASL Release Notes

This document describes the changes made to the SASL application.

### 1.1 SASL 2.1.4

#### 1.1.1 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`.

### 1.2 SASL 2.1.3

#### 1.2.1 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)

### 1.4 SASL 2.1.1

#### 1.4.1 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

### 1.5 SASL 2.1

#### 1.5.1 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 ***
