### General

## Version 1.1.17
### build-system
**Fixes**
* usage output reviewed
* compiling in source tree fixed if YAML config file is used

## Version 1.1.16

### modulecmd
**User visible changes**
* YAML module configuration file. Configured in this file are
  * the release stage
  * the list of systems the module is available
  * the list of systems the module shadowed

  Wherby the items in list of systems are either
  * hostnames or glob style patterns of hostnames (e.g. merlin-*)
  * OS names like rhel7
  
  The filename is `.config-<version>` and is located in the same directory as the modulefile.
  For now the `.release-<version>` files are still used if no YAML configuration file exist.

### build-system
**User visible changes**
* YAML build configuration files. For now `variants` files are still supported.

---

## Version 1.1.15

### modulecmd
**User visible changes**
* prevent loading of a module on dedicated systems via blocklist

### build-system
**User visible changes**
* the function to compare versions can now be called with a single
  argument. In this case the given version is compared to version
  of currently build module.

**Internal changes and fixes***
* bugfix: due to a bug in compiling the list of (legacy) config files,
  each module was build twice.

---

## Version 1.1.14

### build-system 
**Internal changes and fixes**
* lookup of default legacy config files fixed

---

## Version 1.1.13

---

## Version 1.1.10 

### modulecmd
**User visible changes**
* New options for `module search`.
  * With the option `--group` the search can be restricted to a
    group.
  * With the option `--newest` only the newest versions are
    displayed.
* `find` as alias for the sub-command `search` added.
* Bugfix: the sub-commands `whatis` and `keyword|apropos` were
  broken by design. 
* Bugfix: after loading a `Pmodules` module, it was not shown with
  `module list`.
* Bugfix in scanning the depth of groups.
* Bugfix: after `module purge` the environment variable
  `PMODULES_HOME` was not defined an more.
* Bugfix: source the shell init file only if a `Pmodules` module
  is loaded.
* Bugfix: unsetting aliases in modulefiles was not handled
  properly in `module purge`

**Internal changes and fixes**
* initialisation error for bash and zsh fixed

### build-system
**User visible changes**
* `modbuild` is now defined as function like `module`. Therefor no
  `Pmodules` module must be loaded to build a module with `modbuild`
* The system can now be defined in the module (YAML) configuration
  file.
* Build dependencies can (and should) now be specified with
  `build_requires` in the YAML configuration file.
* Bugfix: cleanup of modulefiles in overlays fixed. A module can be in
  more than one overlay. These overlays must be specified in the
  module configuration file. 
* Bugfix: querying dependencies from YAML configuration file
  fixed. Under some conditions the string 'null' was in the list
  of dependencies.
* Bugfix: create group directory if it doesn't exist.
* Bugfix: create the module `$PREFIX` before processing the
  install targets not before all targets. If `$PREFIX` is created
  before processing any target and the build fails, `modbuild`
  assumes that the module have been already built successfully.

**Internal changes and fixes**
* code review/re-factoring
* `modbuild` is now using the Bash installed in `Pmodules` itself.
* test code with `set -o nounset`, several issues with this
  setting fixed (not necessarily bugs).

**other changes**
* The build script to bootstrap Pmodules itself doesn't use modbuild
  any more to compile required software packages.  With this change
  we can remove some special cases from modbuild.
* The bootstrap script requires Bash 5.0 or newer now.
* Bugfix: in the `Pmodules` modulefile force the sourcing of the
  shell init script while in mode `load` only.

---

## Version 1.1.9

### modulecmd
**User visible changes**
* Overlay info added to output of sub-command `search`.
* Output of `module search --verbose` revised for better readability.

**Internal changes and fixes**
* The shell`s init file is sourced, when Pmodules is loaded as module.
  This is required if there are changes in the module function or too
  define new shell functions.
* A bug in `libmodules.tcl:module-addgroup()` which crashed 
  `module load ...` has been fixed.
* In versions before 1.1.9 a colon at the beginning or end of `MODULEPATH`
  crashed the module function. This has been fixed. 

### build-system
**User visible changes**
* The command `modbuild` is now defined as shell function analog to
  the `module` command. The main reason to introduce this function
  is due to the fact that Bash version 5 or newer is now required
  by `modbuild`. The function `modbuild` load Bash 5.x as module
  before calling the modbuild-script. If you want to use the script
  directly, a Bash binary with version 5.x must be in PATH.
* If a build-script is in the current working directory,
  `modbuild` can now be called without specifying the build-script.
* In case of an error in a build-step the build process did not 
  abort as it should. This has been fixed.
* The option `--overlay` can now be used
  - to define an overlay if legacy variants files are used
  - to override the overlay in a YAML variants file.
* The new keyword `with` has been introduced in YAML variants file
  to specified hierarchical dependencies.
* The function `pbuild::supported_os` has been
  removed. `pbuild::supported_systems` provides the same
  functionality for legacy configuration files. In YAML module
  configuration files `systems` have to be used.

**Internal changes and fixes**
* bugfix in setting `PATH`
* requires bash 5 or later
