• Apostrophes and special characters in invoice notes no longer appear with a backslash (e.g. it\'s → it's)
• Logo preview in Settings was showing a broken image icon
• Tax rate from price group was not being applied to generated invoices
• Tax rate on PDF was showing 0% when rate was set via price group rather than directly on the client
• Send day was capped at 28 — now correctly supports 1–31 and Last day of month
• Client update returning "Could not update client" error on sites where new database columns hadn't been added yet — self-healing migration now runs automatically

Added

• Multi-line invoice items — each line has its own description, quantity, and unit price
• Invoice notes / memo field — optional text printed at the bottom of the invoice PDF
• Invoice preview — generates a PDF in a new browser tab before sending, with no invoice created or email sent
• Send invoice modal — pre-filled with the client's default line item so sending is still one click, with the option to customise before sending
• Default currency setting in Settings → Your details
• From / sender details on PDF — company name, email, address, company ID, VAT number, IBAN (leave any field blank to hide it)
• Bill to client details on PDF — company ID, VAT number, address per client
• Email send confirmation — Last sent column on the Invoices page shows when the email was last delivered and whether it succeeded or failed
• Search on the Clients and Invoices pages
• Bulk PDF download (ZIP) from the Invoices page — select any invoices with a PDF and download them all at once
• Separate Delete PDF and Delete record actions on invoices — Delete PDF removes the file but keeps the record and revenue figures intact; Delete record removes everything
• Payment reminder enable/disable toggle (Pro)
• Custom SVG icon support for the WordPress admin menu

Improved

• PDF address blocks now display side by side — From on the left, Bill to on the right
• PDF footer now shows your domain on Pro, and "Powered by HandShake Invoicing" on Free
• Send day dropdown expanded to include 1–31 and Last day of month, with graceful fallback for short months
• Pro badges removed from fields when Pro license is active — they only appear as upsell prompts for free users
• All CSS properties use variables for consistent light and dark mode theming
• Dark mode toggle moved inside the Settings form so it sits naturally in the page flow
