Alexandria 4.3.3

2026-09-03

The Relay Review

covers 4.3.1 to 4.3.3

A top-to-bottom review of the relay that carries pushes between Libraries. Nothing you do changes; what changed is how sure we are.

Changes

  • Blocking a peer now also clears anything they had left waiting for you at the relay.
  • A stuck message at the front of your mailbox can no longer hold up the ones behind it.
  • The relay is built from an exact, pinned recipe, and a deploy can never roll it back to an older build by accident.

Alexandria 4.3.0

2026-09-03

The Owner-First Update

Sharing between Libraries now works the way the rest of Alexandria does: your Library proposes, you decide.

New features

  • What a peer sends you lands in your inbox, not in your notes. You file it where it belongs, approve it as suggested, or decline it. Nothing a peer sends is written into your Library on its own.
  • Anything longer than a line travels as a packaged note and arrives as its own note on the other side, instead of a bullet in someone's area page.
  • Receipts tell the truth: received means it is waiting for them, applied means they filed it, declined means they chose not to.

Changes

  • Packaged notes are written in an outbox folder the Library ignores, so a push is never a second copy of what you already know.
  • Filing straight through is now something you switch on per peer, for a trusted automated feed. It is off for everyone by default.

Fixes

  • A read-only Library never receives on its own.

Alexandria 4.2.0

2026-09-03

The Census Update

Every Library says hello to the relay when it is born and each time it starts.

New features

  • A Library that goes quiet for a while is never forgotten by the relay.
  • The relay keeps a second copy of its records, backed up daily.

Alexandria 4.1.4

2026-09-03

The Contacts and WhatsApp Update

covers 4.1.0 to 4.1.4

Two more of your Mac's own stores, read on demand and read-only.

New features

  • Import your contacts, selectively: put names on your message threads, fill the blank fields of People notes you already have, look someone up, or add the people you name. Never the whole address book.
  • Read your WhatsApp history: what did someone send you, what do you owe a reply, catch me up on a group. Media stays where it is.
  • A card exported from Contacts, Google or Outlook works too, on any machine.

Fixes

  • Two contact files can no longer merge two different people into one.
  • Filling in a People note never overwrites a field you already filled.
  • WhatsApp call entries show as calls instead of unknown messages.

Alexandria 4.0.2

2026-09-01

The Federation Update

covers 4.0.0 to 4.0.2

Link your Library to another person's and hand each other work, agent to agent.

New features

  • Pair once with a five-word code and a three-word check, then push a to-do, a note, a fact, or an event straight into their Library, end-to-end encrypted.
  • Push-only and owner-fired: nobody can read or pull from your Library, and nothing leaves until you say so.
  • See what is waiting for you before it is opened, pull back a push you have not delivered yet, and review anything that arrives outside what you allowed.
  • The picture of your brain never overlaps, and hovering a note tells you where it lives.

Changes

  • The Library now lives at ~/Alexandria, out of iCloud's way.
  • The inbox is for imports and deliberate captures, and it gets drained. The agent files what it can file.

Alexandria 3.4.0

2026-08-31

The Signed Update

covers 3.2.0 to 3.4.0

The Library keeps itself current, and only from releases it can prove are ours.

New features

  • Every release is signed. The Library checks the signature before it applies an update and refuses one it cannot verify.
  • Updates are proposed in chat and never applied silently. The previous version stays one rollback away.
  • The software travels inside the Library, so an update needs no account and no token.

Changes

  • A Library on your own machine has no email channel. Everything email would have done, you can ask for in chat.

Alexandria 3.1.4

2026-08-31

The Folder Is the Brain

covers 3.1.0 to 3.1.4

The folder you unzip is the Library itself. The software tucks away inside it.

New features

  • Say “show me my brain” and the Library draws itself: every note a dot, sized by its links, as a picture and as a live pane you can hover and pan.
  • Three more readers for your Mac: a world news briefing from many newsrooms, your screenshots, and your screen time.
  • Update from a fresh zip in one motion; your notes are never touched.

Changes

  • Day one tells the truth about what is switched on and what is not.

Alexandria 3.0.0

2026-08-28

The Single-Folder Release

One zip. Unzip it, open Claude Code inside it, say Install.

New features

  • No accounts, no keys, no technician. A Library stands up on your own machine in one conversation.
  • Everything is plain Markdown in a folder you own, readable in any editor and browsable in Obsidian.

Alexandria 2.117.1

2026-08-21

The Foundations

covers 2.2.0 to 2.117.1, July and August 2026

Where it started: the installer, the launch screen, and the daily habits that make a Library grow.

New features

  • Paste anything and say “file this”. The Library breaks it into pieces, proposes a home for each, and files on your approval.
  • The daily motions: good morning, what is on my plate, debrief, log this.
  • People, events, areas, knowledge. Every note linked, every change a commit, nothing silently lost.
  • Structured retrieval that knows who is who: resolve a person, trace the links, route a fact.

Every change, in full technical detail, is in the complete changelog on GitHub. The launch screen shows the current release's notes too.
