JSignPdf 3.1.0 released

[Josef Cacek]

Hi all,

JSignPdf 3.1.0 is out:
https://github.com/intoolswetrust/jsignpdf/releases/tag/JSignPdf_3_1_0

Highlights:

- Native installers for every platform (Windows MSI, Linux DEB/RPM, macOS DMG,
  plus Flatpak), each with a bundled Java runtime - no system Java needed.
  The fat jar is gone; two cross-platform ZIPs remain for Java 21 users.
- Pluggable signing engines (--engine / Preferences), including a new EU DSS
  engine producing PAdES B, T, LT and LTA signatures.
- Windows MSI installers are now Authenticode-signed via SignPath (Thanks for the sponsorship).

Heads-up on two changed defaults: signing now uses SHA-256 instead of SHA-1
where no algorithm is set, and CLI signatures append by default (use
--overwrite for the old behavior).

Thanks to @JohnPlanetary for driving the PAdES verification effort behind the
DSS engine, @Sesivany for the Flatpak packaging, @sam2kb for the UX
improvements, and to all translators - 18 languages updated this release, with
special thanks to albanobattistella (Italian), Milo Ivir (Croatian) and
தமிழ்நேரம் (Tamil).
