v1.24.8

Group front-matter variables in templates

Breaking configuration change. If you use custom templates, please update them:

Front matter variables in templates must be preceeded with `fm.`, e.g.
`fm_author` becomes `fm.fm_author`, `fm_title` becomes `fm.fm_title`,
`fm_subtitle` becomes `fm.fm_subtitle` and so on.

v1.24.7

Viewer: add $$ syntax for inline formula

Since the version 1.19.8 Tp-Note can render mathematical formula. So far
inline formula had to be enclosed between `$ and $`. e.g. `$\alpha$`.
This former syntax, is still supported, is now deprecated.
The present release adds support for the standard syntax with simple $
enclosure, e.g. $\alpha$.

The former syntax for display formula:

```math
\alpha
```

can now be written as:

$$
\alpha
$$

v1.24.6

Revert migration to the `mdka` crate

The reverted change was introduced in v1.24.5. Unfortunately everyday usage
shows, that the `mdka` crate is not as mature as the former solution with
the `fast_html2md` crate.

Otherwise, no new features. The `extensions` table of the `zettel` scheme was
updated. This concerns only users of the `zettel` scheme _not_ using Markdown.

v1.24.4

Downgrade some dependencies to comply with rustc 1.77.2, no code changes

v1.24.3

Enhance the HTML clipboard configuration options

This release extends the `html_to_markup` filter by adding a `default=`
parameter in case the filter fails, its result is the empty string, or if
the filter is disabled for a certain markup language with the configuration
variable `extensions.1`.

The `clipboard` variable is replaced by the variables `txt_clipboard` and
`html_clipbaord`. They both represent the clipboard's text content. The
difference is, that the `html_clipboard` carries HTML formatting along the
text, while `txt_clipboard` holds the plain text only.

v1.24.2

Regression fix: repair broken Windows installer

This updates the tool chain that produces the Windows installer. The `.msi`
installer was broken in version 1.24.1.

Minor bug fix:

* Windows: do not insert double `\r\r` when input comes from both: stdin and
  the clipboard.

v1.24.1

Regression bug fix: no HTML in X11 clipboard, fallback to text

This release fixes a regression (commit dc9fd8d) introduced with the
migration to the `clipboard-rs` crate (commit b532b71) under Linux/X11:
When the clipboard contains no HTML, now the plain text content is
correctly used (again).

Minor internal improvements:

* Refactor clipboard related templates

v1.24.0

Add clipboard HTML to Markdown converter

This release of adds internal clipboard HTML detection and conversion to
Markdown.

In earlier versions the conversion of clipboard HTML content into Markdown was
performed in the Browser by the plugins _Copy Selection as Markdown_ and _Copy
as Markdown_ only. Now, this conversion can be done by Tp-Note also without
browser plugin.

For best results browser plugins are still preferred, because in addition to the
selected content, the plugins insert also a link to the displayed page. Without
plugin this information must be completed by hand. Nevertheless, the internal
converter does a good job with quickly copying hyperlinks into Tp-Note files.

v1.23.10

Security release for RUSTSEC-2024-0019, no new features

The vulnerability RUSTSEC-2024-0019 was found in one of Tp-Note's
dependencies. For those who compile Tp-Note, this is fixed by a simple
`cargo update`. Nevertheless, some distributions (e.g. NixOS), refer to
the exact versions in `Cargo.lock`, which motivates this new release.

Internal changes and refactoring:

* Build chain: migrate from Docker to Podman
* Encapsulation of the clipboard related code.

v1.23.9

Correct the last git release tag. No source code change.

This corrects the last git release tag (without `v`) which caused downstream
build scripts to fail.
