Unofficial ProtonMail Desktop App
What's new in 5.3.8
Fix a bug where attachments could go missing during EML export from local store mode (85a4613, #771). This was happening because the app wasn't handling case properly in the "Content‑Disposition" header when figuring out attachment types. Bug was introduced in the previous release during fixing EML export attachments duplication issue. Update project dependencies. Including the @electron and packaged Proton Web Clients stack.
