Updates should follow the Keep a CHANGELOG principles.

0.1.0-alpha - 2026-11-11

Added

• MessengerType, KnownMessenger, Handle, Messengers; InstantMessengerException and InvalidHandle. Messengers::detect() reads the input once, and a service parses a link only when it publishes one and the input has a dot. Handle::fromCanonical() takes back a handle kept in its canonical form without reading it again, so a phone number a later import of the numbering plans does not know still loads.
• Phone numbers read by phil/phone: in their international form, in their country's plan, without an extension; shown in the international format.
• Telegram's own pages, t.me/joinchat/…, t.me/addstickers/…, t.me/proxy and the like, are not user names.
• LINE official accounts: @id, and the links line.me/R/ti/p/@id, kept with their @ and linked as https://line.me/R/ti/p/@id; the links line.me/R/ti/p/~id are read. A LINE friend code, line.me/ti/p/AbCd…, is not a LINE ID.
• XMPP: an address with ?, # or a control character in its user is refused, and link() percent-encodes the user as RFC 5122 writes it, so an xmpp: link opens a conversation with the address shown, never another.
• The documentation in doc/, one file per topic, indexed by the README.
• CONTRIBUTING.md, SECURITY.md and CODE_OF_CONDUCT.md.
