# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a
Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to
[Semantic Versioning](http://semver.org/spec/v2.0.0.html).
## [Unreleased]
## [v3.0.1] - 2024-10-20
### Changed
- Improved the error message when the font size is not a positive length.
- Documentation improvements.
## [v3.0.0] - 2024-10-05
### Added
- Added new `expl3` public variables that store the current font step, font
scale, font size, and font baselineskip. They are set in the `selectfont`
hook.
- `\l_fontscale_step_fp`
- `\l_fontscale_scale_fp`
- `\l_fontscale_size_dim`
- `\l_fontscale_baselineskip_skip`
### Changed
- This update includes some changes that are backwards incompatible.
- The package commands now use the above variables instead of `\f@size` and
`\f@baselineskip`. This changes the behavior of `\CurrentFontStep`,
`\CurrentFontScale`, and `\CurrentFontSize` within the second argument of
`\fontsize` because `\fontsize` sets `\f@size` to the new font size before
expanding its second argument.
- `\PrintFontSizeCommand` no longer tests if the current font baselineskip
equals the font baselineskip of any font size command from `\tiny` to
`\Huge`.
- `\SetFontStep` now rounds the new font step to 5 decimal places. This is
important when checking if it equals the font step of any font size command
from `\tiny` to `\Huge`.
- A default `pt` is now appended only in user-level commands, not in internal
`expl3` functions.
- `\fontscalesetup` now processes the keys slightly faster when the key
`<font size command>/baselineskip` is not set.
- Documentation improvements.
### Removed
- `\CurrentFontSizeCommand` (redundant with `\CurrentFontSize` and
`\CurrentFontBaselineskip`)
### Fixed
- The error message for `\SetFontStep*` when the current font step is undefined
no longer writes `\SetFontStep*`. This would be incorrect if its
corresponding internal function was used instead of `\SetFontStep*`.
- The internal functions of `\PrintSampleText` now correctly enclose their
contents within a group.
## [v2.4.0] - 2024-09-10
### Changed
- `\fontscalesetup` no longer issues a warning if the lengths of the font
baselineskips are not ordered from `\tiny` to `\Huge`.
- Code improvements.
## [v2.3.0] - 2024-09-06
### Changed
- The package commands no longer check if the font baselineskip is less than
the font size.
## [v2.2.0] - 2024-08-29
### Changed
- Improved the messages issued by this package.
### Added
- `\SetFontBaselineskip`
## [v2.1.0] - 2024-08-12
### Changed
- Documentation improvements.
### Added
- `\CurrentFontSizeCommand`
## [v2.0.0] - 2024-08-02
### Changed
- This update includes many changes that are backwards incompatible.
- The documentation has been completely rewritten.
- Package description changed from "A user interface for setting document font
sizes" to "A flexible interface for setting font sizes".
- The code no longer uses `\@setfontsize`.
- The font size commands provided by this package now do nothing, except issue
a warning, if used in math mode.
- The base font size of the musical typographic scale is now set by the new key
`musical/base`.
- `\PrintFontParameters` renamed to `\PrintFontSizeParameters`.
- `\PrintAllFontParameters` renamed to `\PrintAllFontSizeParameters`.
- `\PrintSampleText` uses a `+m`- instead of an `O`-type argument.
- `\PrintFontSizeCommand` prints `\undefined` instead of `UNDEFINED`.
- `\fontscalesetup` is now removed in `\text_purify:n`.
### Removed
- Keys `typographic-scale=modular` and `modular`.
- Key `ignore-order` (no support for using `\tiny` to `\Huge` in the wrong
order).
- Key `reset` (very rarely used).
- Public `prop` variables for each font size command from `\tiny` to `\Huge`.
(They are redundant with the other public variables and programmers will very
likely prefer using their own `prop` variables.)
### Added
- `\fontscalesetup` now has an optional starred argument which first resets the
keys to their initial values.
- Key `musical/base` (explained earlier).
- The package commands now issue a user-friendly error message if the font size
is a zero or negative length.
- The package commands now issue an error if the font baselineskip is less than
the font size.
- The package commands that would produce a low-level error if used in math
mode now issue a user-friendly error message instead.
### Fixed
- Now correctly checks that the package requires `LaTeX2e` version 2023-11-01
or newer.
- The keys `<font size command>` no longer incorrectly treat a `/` within a
brace group as the delimiter.
## [v1.3.0] - 2024-05-17
### Added
- `\fontscalesetup` now provides error checking for the keys `modular/ratio`,
`musical/ratio`, and `musical/notes`.
- It is now documented that `\fontscalesetup` uses `\normalsize` after it
finishes processing the package keys.
### Changed
- The code now regularly uses `V`- and `v`-type arguments to get the value of a
variable.
- The code now uses private `expl3` wrappers around the `LaTeX2e` commands
`\@setfontsize`, `\fontsize`, and `\selectfont`.
## [v1.2.2] - 2024-04-29
### Changed
- Improved package messages when issuing errors and warnings.
- Code improvements.
### Fixed
- The documentation no longer incorrectly compares `\ScaleFont` with
`\scalefont` from the `scalefnt` package.
- The internal function for the key `reset=preamble` now correctly initializes
to `\prg_do_nothing:`.
## [v1.2.1] - 2024-04-21
### Changed
- Improved the error message for `\SetFontStep*` when the current font step is
undefined.
- Documentation improvements.
## [v1.2.0] - 2024-04-15
### Added
- It is now documented that the keys and commands provided by this package take
as a value or argument a dimen, skip, floating point, or integer expression
instead of simply a size, skip, number, or integer.
- This package now includes a CHANGELOG file.
### Changed
- Documentation improvements.
### Fixed
- The key `reset=preamble` and `\SetFontStep` no longer rely on undocumented
`expl3` features.
- Corrected typo in the documentation.
## [v1.1.1] - 2024-04-07
### Changed
- Improved performance, especially when using a musical typographic scale.
- Small documentation improvements.
## [v1.1.0] - 2024-03-31
### Added
- `\SetFontStep`, `\SetFontScale`, `\SetFontSize`, `\ScaleFont`, and
`\SetFontSizeBaselineskip` are now set up to work with `\text_purify:n`.
## [v1.0.3] - 2024-03-26
### Changed
- Code improvements, particularly to document commands defined with optional
arguments.
## [v1.0.2] - 2024-03-22
### Changed
- Performance and code improvements.
### Fixed
- Fixed issue where the key `reset=preamble` relied on an unsupported `V`-type
`bool` argument.
## [v1.0.1] - 2024-03-08
### Added
- Added the `.tex` sources for the documentation.
- Added the CTAN link to the `.sty` and README files.
## [v1.0.0] - 2024-03-06
### Added
- First official release to CTAN.
