Stirling PDF

Lots of changes in todays release! We have some brand new features and enhancements but we have a reworked our analytics! Our opt-in (disabled by default) analytics are now all unified under the same parameter and has been made easier to disable in both settings.yml and consent banner. You can see more about it here https://docs.stirlingpdf.com/analytics-telemetry/ . These changes include both posthog and scarf and should make it easier for users to disable things.

Our major feature changes this release include

• New PDF to Vector image conversion
• Extract attachments feature
• Enhanced get info for clearer UI and extra information

Some notable other changes are

• Fixed bug causing large file sizes in multi-tool
• Fixed bug causing large file in extract pages
• Various security fixes and hardening

Thanks again to the OSS community and yet again to @balazs-szucs and @Ludy87 for keeping stirling alive with all the new features and fixes!
