This is the changelog for Calamares. For each release, the major changes and
contributors are listed. Note that Calamares does not have a historical
changelog -- this log starts with version 3.3.0. See CHANGES-3.2 for
the history of the 3.2 series (2018-05 - 2021-12).

# 3.3.0 (unreleased) #

This release contains contributions from (alphabetically by first name):
 - Anubhav Choudhary
 - Evan James
 - Vitor Lopes

This is a "minor" version change, but the size of the changes is very
large. Configuration files from previous versions of Calamares will
**certainly** need to be re-validated. Take heed of the many changes
in the *Modules* heading, below.

Users (distributions) are **strongly** advised to use the tools
for configuration validation (`ci/configvalidator.py`) to check
that the distribution configuration files follow the current schema.

## Project ##
 - The C++ code in the project is now formatted with clang-format 12 or 13,
   with the coding-style as found in `.clang-format`; there are minor
   differences from the tool, compared to the clang-format 9 usually applied
   to Calamares 3.2.
 - The CMake code in the project is now formatted with gersemi 0.7.5.

## Core ##
 - CMake 3.16, Qt 5.15 are now required; the newer CMake is to support
   new features (also for KDE Frameworks), Qt is the current LTS version.
 - Running `calamares -d` no longer enforces a single-application
   (it is for debugging purposes, after all).
 - Python 3.6 or later is now required, to allow for F-strings in
   Python code and allow other tidy-ups in the Python modules.
   Boost::Python now requires 1.67 or later (for CMake support).
 - The log file now **always** contains a debug-log, and the `-D` flag
   primarily controls what is printed to stdout. By default, stdout
   only gets errors; use `-D6` to match stdout with the file. Use `-D8`
   to get an extra-verbose log file **and** verbose stdout.

## Modules ##
 - *bootloader* now supports more options when building the kernel
   command-line. (Thanks Evan)
 - *displaymanager* no longer supports the discontinued *kdm* display manager.
 - *fstab* configuration has been completely re-done. Many configuration
   options have moved to the *mount* module. See #1993
 - *grubcfg* changed the key *keepDistributor* to *keep_distributor*.
   Please update configurations.
 - *mount* now does most of the mounting; options that were in *fstab*
   have moved here. See #1993
 - *partition* requires KPMCore 21.12 (e.g. KPMCore 4.2 API, or later).
 - *partition* can now skip installing the bootloader in more scenarios.
   #1632 (Thanks Anubhav)
