Changelog

• Build a message schema from a real payload. Paste a message you already have and the generator builds the form from it — objects, nested arrays and all. Values become generators of the matching kind, so a pasted UUID produces a fresh UUID per message rather than the same one ten thousand times.
• Fixed values for fields that must match real data. Most fields want to vary; a tenant id or an area id has to match a row that already exists, or the consumer will reject the message. Set those to fixed and type the value. Numbers stay numbers and strings stay strings, because a consumer validates the type as well as the value.
• A full reference inside the Bulk publish window. Every field type with its options and defaults, how keys shape the JSON, the date syntax, header placeholders and the per-run limits — folded away until you want it.
• Header names are shown in full. The message detail panel no longer clips a header name to fit its column, so a long one — a Symfony stamp, a routing header with a descriptive suffix — reads as itself instead of the prefix it shares with every other.
• The cache opens without the broker. Off VPN, or on a plane, the messages you already downloaded are still there to read, search and export — the queue list comes from the cache, and anything that genuinely needs a live broker is disabled rather than failing when you click it.
• Headers are sent exactly as written. A value that looks like JSON — a Symfony Messenger stamp, say — now travels as the string you typed instead of being turned into a nested structure on the wire.
• Republish sends headers exactly as Publish does. A header value travels as the text you see in the field — a Symfony Messenger stamp goes back out as the string it was, instead of being rewritten into a nested structure — and {{uuid}} and the other placeholders now work when replaying a message too.

• Dates in your own format. A date type, and datetime takes a format in its options — Y-m-d for a plain date, or Y-m-d H:i:s|-7 days..now to land somewhere in a window. Times are UTC.
• Real JSON arrays. Write items[0].sku and you get an array. Nesting works to any depth, and a gap in the indices is filled with null so the result stays an array.
• A null field type, in message bodies and header templates alike.
• Every option says what it accepts. Each field type shows its own syntax hint, and a malformed key is caught in the preview with the field named.

• Connection tests report the vhost. Testing a connection now names the vhost, says how many queues are in it, and lists the ones that exist if the name does not match — the answer you are actually after when a broker responds but a queue list looks wrong.
• The queue list says where it looked. An empty sidebar names the vhost it searched, or tells you queues are hidden because they are empty, with one click to show them.

• The trial tells you when it is ending. A notice appears five days out and gets firmer as the date approaches. Cached messages and environments are never touched — a licence simply unlocks the app again.

• Reclaim disk space from a cleared cache. Clearing the message cache empties it but does not shrink the file — SQLite keeps the freed pages for reuse, so a cleared cache can still occupy gigabytes. Environment settings show how much can be handed back, and offer a button to do it. It appears only when there is something worth reclaiming.

Development builds, before the app was generally available. What they brought:

• Signed and notarized by Apple, so macOS opens the app without a detour through System Settings.
• Report a bug from inside the app, with the diagnostics attached and shown to you first.
• Cache size per environment, and clearing a cache without needing the broker to be reachable.
• Visible progress on every action that talks to a broker.
• A separate AMQP host, for brokers whose management interface and message port live at different addresses.
• Precise partial fetches — asking for the first N messages fetches exactly that.
