## [Unreleased]

## [v3.1.0] – 2023–07–04

### Changed

- The `lua-widow-control` package causes build failures in different settings,
  although the same TeX Live version is used.  Until this can be resolved, we
  deactivate the loading of this package from `se2packages` by default.  It can
  still be activated manually by adding the `widowcontrol=true` option to the
  `se2packages` package.
- Set penalties for widows and orphans only if `lua-widow-control` package is
  not loaded.
- Change the formatting of chapter headings.

## [v3.0.0] – 2023–04–18

### Added

- Add documentation on how to install the bundle if it is not part of the
  existing TeX distribution.
- Add a package `se2packages` that provides the ability to directly load
  recommended packages with recommended options.

### Changed

- The `paper=a4` and `paper=b5` options now produce the exact same text-block
  sizes.
- Make the logo height smaller for B5 paper.
- The default class is now `scrbook` instead of `scrreprt`.

### Removed

- **Breaking:** Removed the `biblatex` class option from `se2thesis`, use the
  `se2packages` package with its `biblatex=true` option instead.
- **Breaking:** Removed the `paper=a5` option.
- Removed the automated loading of the `microtype`, `selnolig`, and
  `lua-widow-control` packages from `se2thesis`—use `se2packages` instead.

## [v2.1.0] – 2023–01–27

### Added

- Add license text of LaTeX Project Public License (LPPL) to repository
- Add a continuous integration pipline using GitHub Actions
- Add styling for chapter, section, and sub-section headings

### Fixed

- Fix the font selection in the documentation of `se2fonts` to only use the
  filename but not the font name
- Fix the definitions of `\frontmatter`, `\mainmatter`, and `\backmatter` to
  match the definitions from KOMA Script's `scrbook` class.

## [v2.0.0] – 2023–01–10

### Added

- A file `se2thesis.tex` that contains the combined documentation from all DTX
  files as well as their code
- Use Libertinus and Fira Code as fonts

### Changed

- Split the large `se2thesis.dtx` into several DTX files for the different packages
- Deprecate the `fmode` argument to `se2fonts.sty`.  *Attention:* This is a breaking change!
- The `build.lua` now also builds all `*.tex` files
- Use the default back-reference styling of `biblatex`
- Changed the dimensions of the type area

### Fixed
