CHANGES

@@ -6,6 +6,49 @@ This is the changelog for Calamares-Extensions. For each release, the major
 changes and contributors are listed. Note that Calamares-Extensions does not
 have a historical changelog -- this log starts with version 1.0.0.
 
+# 1.3.2 (2023-08-28)
+
+We skipped a couple of releases in the release-notes, then tagged
+1.3.1 without a version bump or release-notes. So 1.3.2 brings us
+back to "regular releases".
+
+This release contains contributions from (alphabetically by first name):
+ - Anke Boersma
+ - Nathan Schulte
+ - Oliver Smith
+ - stravanpannala
+ - undef
+
+Changes and new modules in this release:
+ - *mobile* Has new configuration options. (Thanks Nathan, Oliver)
+ - *unpackfsc* Uses a more portable invocation of tar. (Thanks sravanpannala)
+
+
+# 1.2.1 (2021-11-16)
+
+The 1.2.0 release had no release-notes for that version, and failed to
+credit Anke and Otus.
+
+Changes and new modules in this release:
+ - *unpackfsc* can use `fsarchiver` and unpack that, instead of squashfs;
+   a distro might choose one tool or the other. Currently, only *savedir* /
+   *restdir* mode (i.e. directories, not block-devices) are supported.
+
+# 1.2.0 (2021-11-16)
+
+This release contains contributions from (alphabetically by first name):
+ - Anke Boersma
+ - Otus9051
+
+Changes and new modules in this release:
+ - *refind* is a new module that installs the rEFInd bootloader. It can
+   be used instead of the *bootloader* module from core Calamares. (Thanks Anke)
+ - *unpackfsc* is a new module that uses `unsquashfs` directly. This may
+   be faster or more convenient than the *unpackfs* module from core Calamares.
+   The configuration file supports only one entry, but is otherwise easy to
+   adapt from an existing `unpackfs.conf`.

+# Contributing to Calamares Extensions
+
+Welcome to Calamares! We're happy that you would like to add
+something to Calamares -- by extending it!
+This contribution guide is minimal:
+all the **technical** parts of contributing to
+Calamares Extensions are the same as [contributing to Calamares](https://github.com/calamares/calamares/CONTRIBUTING.md).
+
+
+## Code of Conduct
+
+The Calamares community -- of developers, translators, and downstream (distro) users --
+aims to be courteous, professional, and inclusive. Harrassment, discriminatory
+statements and abuse are not tolerated. In general, we apply the
+[KDE Code of Conduct](https://www.kde.org/code-of-conduct/) and the
+[GNOME Code of Conduct](https://wiki.gnome.org/Foundation/CodeOfConduct) (the
+rules of decent behavior in both communities are pretty much the same).
+
+> See the [CoC section on the wiki](https://github.com/calamares/calamares/wiki#code-of-conduct)
+> for a longer text. To report a problem, please contact the maintainer,
+> Adriaan de Groot, or the KDE Community Working Group.
+
+
+## Join the Conversation
+
+GitHub Issues are **one** place for discussing Calamares and its extensions if there are concrete
+problems or a new feature to discuss.
+Issues are not a help channel.
+Visit Matrix for help with configuration or compilation.
+
+Regular Calamares development chit-chat happens in a [Matrix](https://matrix.org/)
+room, `#calamares:kde.org`. Responsiveness is best during the day
+in Europe, but feel free to idle.
+Matrix is persistent, and we'll see your message eventually.

+
+CC0 1.0 Universal CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES
+NOT PROVIDE LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE
+AN ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS INFORMATION
+ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE USE
+OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED HEREUNDER, AND DISCLAIMS
+LIABILITY FOR DAMAGES RESULTING FROM THE USE OF THIS DOCUMENT OR THE INFORMATION
+OR WORKS PROVIDED HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer exclusive
+Copyright and Related Rights (defined below) upon the creator and subsequent
+owner(s) (each and all, an "owner") of an original work of authorship and/or
+a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for the
+purpose of contributing to a commons of creative, cultural and scientific
+works ("Commons") that the public can reliably and without fear of later claims
+of infringement build upon, modify, incorporate in other works, reuse and
+redistribute as freely as possible in any form whatsoever and for any purposes,
+including without limitation commercial purposes. These owners may contribute
+to the Commons to promote the ideal of a free culture and the further production
+of creative, cultural and scientific works, or to gain reputation or greater
+distribution for their Work in part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any expectation
+of additional consideration or compensation, the person associating CC0 with
+a Work (the "Affirmer"), to the extent that he or she is an owner of Copyright
+and Related Rights in the Work, voluntarily elects to apply CC0 to the Work
+and publicly distribute the Work under its terms, with knowledge of his or
+her Copyright and Related Rights in the Work and the meaning and intended
+legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be protected
+by copyright and related or neighboring rights ("Copyright and Related Rights").
+Copyright and Related Rights include, but are not limited to, the following:
+
+i. the right to reproduce, adapt, distribute, perform, display, communicate,
+and translate a Work;
+
+      ii. moral rights retained by the original author(s) and/or performer(s);
+
+iii. publicity and privacy rights pertaining to a person's image or likeness
+depicted in a Work;
+
+iv. rights protecting against unfair competition in regards to a Work, subject
+to the limitations in paragraph 4(a), below;
+
+v. rights protecting the extraction, dissemination, use and reuse of data
+in a Work;
+
+vi. database rights (such as those arising under Directive 96/9/EC of the
+European Parliament and of the Council of 11 March 1996 on the legal protection
+of databases, and under any national implementation thereof, including any
+amended or successor version of such directive); and
+
+vii. other similar, equivalent or corresponding rights throughout the world
+based on applicable law or treaty, and any national implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of,
+applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
+unconditionally waives, abandons, and surrenders all of Affirmer's Copyright
+and Related Rights and associated claims and causes of action, whether now
+known or unknown (including existing as well as future claims and causes of
+action), in the Work (i) in all territories worldwide, (ii) for the maximum
+duration provided by applicable law or treaty (including future time extensions),
+(iii) in any current or future medium and for any number of copies, and (iv)
+for any purpose whatsoever, including without limitation commercial, advertising
+or promotional purposes (the "Waiver"). Affirmer makes the Waiver for the
+benefit of each member of the public at large and to the detriment of Affirmer's
+heirs and successors, fully intending that such Waiver shall not be subject
+to revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be
+judged legally invalid or ineffective under applicable law, then the Waiver
+shall be preserved to the maximum extent permitted taking into account Affirmer's
+express Statement of Purpose. In addition, to the extent the Waiver is so
+judged Affirmer hereby grants to each affected person a royalty-free, non
+transferable, non sublicensable, non exclusive, irrevocable and unconditional
+license to exercise Affirmer's Copyright and Related Rights in the Work (i)
+in all territories worldwide, (ii) for the maximum duration provided by applicable
+law or treaty (including future time extensions), (iii) in any current or
+future medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional purposes
+(the "License"). The License shall be deemed effective as of the date CC0
+was applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder of
+the License, and in such case Affirmer hereby affirms that he or she will
+not (i) exercise any of his or her remaining Copyright and Related Rights
+in the Work or (ii) assert any associated claims and causes of action with
+respect to the Work, in either case contrary to Affirmer's express Statement
+of Purpose.
+
+   4. Limitations and Disclaimers.
+
+a. No trademark or patent rights held by Affirmer are waived, abandoned, surrendered,
+licensed or otherwise affected by this document.
+
+b. Affirmer offers the Work as-is and makes no representations or warranties
+of any kind concerning the Work, express, implied, statutory or otherwise,
+including without limitation warranties of title, merchantability, fitness
+for a particular purpose, non infringement, or the absence of latent or other
+defects, accuracy, or the present or absence of errors, whether or not discoverable,
+all to the greatest extent permissible under applicable law.
+
+c. Affirmer disclaims responsibility for clearing rights of other persons
+that may apply to the Work or any use thereof, including without limitation
+any person's Copyright and Related Rights in the Work. Further, Affirmer disclaims
+responsibility for obtaining any necessary consents, permissions or other
+rights required for any use of the Work.
+
+d. Affirmer understands and acknowledges that Creative Commons is not a party
+to this document and has no duty or obligation with respect to this CC0 or
+use of the Work.

+# Possible modes are "optional", "required" (for zero-or-one or exactly-one)
+# or "optionalmultiple", "requiredmultiple" (for zero-or-more
+# or one-or-more).
+mode: required
+
+# Software installation method:
+#
+# - "legacy" or "custom" or "contextualprocess"
+#   When set to "legacy", writes a GlobalStorage value for the choice that
+#   has been made. The key is *packagechooser_<id>*. The module's
+#   instance name is used; see the *instances* section of `settings.conf`.
+#   If there is just one packagechooser module, and no special instance is set,
+#   resulting GS key is probably *packagechooser_packagechooser*.
+#
+#   The GS value is a comma-separated list of the IDs of the selected
+#   packages, or an empty string if none is selected.
+#
+#   With "legacy" installation, you should have a contextualprocess or similar
+#   module somewhere in the `exec` phase to process the GlobalStorage key
+#   and actually **do** something for the packages.
+#
+# - "packages"
+#   When set to "packages", writes GlobalStorage values suitable for
+#   consumption by the *packages* module (which should appear later
+#   in the `exec` section. These package settings will then be handed
+#   off to whatever package manager is configured there.
+#
+# - "netinstall-select"
+#   When this is set, the id(s) selected are passed to the netinstall module.
+#   Any id that matches a group name in that module is set to checked
+#
+# - "netinstall-add"
+#   With this method, the packagechooser module is used to add groups to the
+#   netinstall module.  For this to have any effect.  You must set netinstall,
+#   which is described below.
+#
+# There is no need to put this module in the `exec` section. There
+# are no jobs that this module provides. You should put **other**
+# modules, either *contextualprocess* or *packages* or some custom
+# module, in the `exec` section to do the actual work.

+#  - *step*, used in the overall progress view (left-hand pane)

+# Each key can have a [locale] added to it, which is used as
+# the translated string for that locale. For the strings

+# below), or use existing AppData XML files, or use AppStream cache

+#       ID for the product. The ID "" is special, and is used for
+#       "no package selected". Only include this if the mode allows
+#       selecting none. The name and description given for the "no package
+#       selected" item are displayed when the module starts.
+#
+# Each item must adhere to one of three "styles" of item. Which styles
+# are supported depends on compile-time dependencies of Calamares.
+# Both AppData and AppStream may **optionally** be available.
+#
+# # Generic Items #
+#
+# These items are always supported. They require the most configuration
+# **in this file** and duplicate information that may be available elsewhere
+# (e.g. in AppData or AppStream), but do not require any additional
+# dependencies. These items have the following **mandatory** fields:
+#
+#  - *name*
+#       Human-readable name of the product. To provide translations,
+#       add a *[lang]* decoration as part of the key name, e.g. `name[nl]`
+#       for Dutch. The list of usable languages can be found in
+#       `CMakeLists.txt` or as part of the debug output of Calamares.
+#  - *description*
+#       Human-readable description. These can be translated as well.
+#  - *screenshot*
+#       Path to a single screenshot of the product. May be a filesystem
+#       path or a QRC path, e.g. ":/images/no-selection.png". If the path
+#       is not found (e.g. is a non-existent absolute path, or is a relative
+#       path that does not exist in the current working directory) then
+#       an additional attempt is made to load the image from the **branding**
+#       directory.
+#
+# The following fields are **optional** for an item:
+#
+#  - *packages* :
+#       List of package names for the product. If using the *method*
+#       "packages", consider this item mandatory (because otherwise
+#       selecting the item would install no packages).
+#
+#  - *netinstall* :
+#       The data in this field should follow the format of a group
+#       from the netinstall module documented in
+#       src/modules/netinstall/netinstall.conf.  This is only used
+#       when method is set to "netinstall-add"
+#
+# # AppData Items #
+#
+# For data provided by AppData XML: the item has an *appdata*
+# key which points to an AppData XML file in the local filesystem.
+# This file is parsed to provide the id (from AppData id), name
+# (from AppData name), description (from AppData description paragraphs
+# or the summary entries), and a screenshot (the default screenshot
+# from AppData). No package is set (but that is unused anyway).
+#
+# AppData may contain IDs that are not useful inside Calamares,
+# and the screenshot URL may be remote -- a remote URL will not
+# be loaded and the screenshot will be missing. An item with *appdata*
+# **may** specify an ID or screenshot path, as above. This will override
+# the settings from AppData.
+#
+# # AppStream Items #
+#
+# For data provided by AppStream cache: the item has an *appstream*
+# key which matches the AppStream identifier in the cache (e.g.
+# *org.kde.kwrite.desktop*). Data is retrieved from the AppStream
+# cache for that ID. The package name is set from the AppStream data.
+#
+# An item for AppStream may also contain an *id* and a *screenshot*
+# key which will override the data from AppStream.
