Last Week in Pony

Last Week in Pony - April 19, 2026

Two theme songs this week. The topical pick is “New York Groove”, because I spent most of the week back in NYC. Apropos. But the real theme song is “Dollar Bill Bar” because OMFG, I love that little damn song so much. You go Sierra. You fucking go. Right, umm, where was I. Oh yeah. Pony shit.

Big week. ponyc 0.63.2 is out with a pile of pony-lsp work that makes your editor a lot more useful. ponylang/postgres 0.5.0 is a security-hardening release that closes a SCRAM mutual-authentication bypass, requires SCRAM by default, and routes a stack of protocol failures to your application instead of crashing the driver. contact-red/sensitive shipped its first release and gives you a clean way to keep secrets out of your log files. And three networking libraries picked up timer failure callbacks so you actually find out when your timer subsystem has fallen over. Let’s dig in.

I’m going to be traveling a lot during the next couple weeks, so our theme song this week is Willie Nelson’s “On the Road Again”. A true classic. And for a true story: once upon a time I was a young child and met another kid while we were both sitting on Willie’s lap at his 4th of July picnic. Years later, I met him again at a bar in NYC when he came up from Texas to hang out with a good friend who was one of my best friends. Small world, right? Willie Nelson, bringing together awesome people since the time of the dinosaurs.

All that aside, we have some great stuff as usual happening in Pony land. ponyc 0.63.1 is out and has safety-related fixes you need. ponylang/postgres 0.3.0 is a monster of a release. A pile of networking libraries went out that you’ll want to grab. And there’s a whole pitch to make about LLMs and Pony. Let’s dig in, because it all just fucking rocks. Get on board this train while there is still time. That’s what I’m saying. Get the fuck on board. Oh, and Cloudsmith has throttled us until the end of the day today UTC so, sorry, you can’t download any prebuilt binaries until that has lifted.

This week’s theme song was pulled directly from the pool of “things to appeal to Sean musically.” I give you “Apocalypse” by The Darts. Man, this one is great. Big week to go with it. ponyc 0.63.0 is out and you need to update. ponylang/hobby threw out its middleware and rebuilt around interceptors. And there’s a whole repo of Claude Code skills for Pony. Three big things and I’m excited about every one of them. Let’s go.

ponyc 0.62.1 is out and you need to update. There’s a type system soundness hole in there, a Windows crash that we didn’t fully nail last time, and a bunch more. Beyond ponyc, ponylang/hobby threw out its old handler model and rebuilt it around actors the way Pony wants you to build things. Big week. Let’s crank up an oldie but a goodie, “Son of a Pig Farmer” by Krylls, and get into it.

ponyc 0.62.0 is out and you should update. There are bug fixes in there that matter, including one that was quietly breaking SSL hostname verification. Beyond that, there’s a new multipart MIME parser, four new patterns, and pony-lsp landed in Helix. Let’s get into it, but first, fire up this week’s theme song: “Bloody Mary Morning” by Willie Nelson. Bob Wills might still be the king, but Willie is certainly in the royal court. Oh, and be prepared for lots of homework.

This week’s theme song is Rawhide and it’s so good, we are gracing you with 3 different versions. And this week calls for multiple versions because it has been a big week:

  • ponyc 0.61.0 shipped with a new \exhaustive\ annotation for match expressions
  • Three new libraries hit their first releases
  • Eight Pony patterns were published
  • The website got a top-to-bottom reorganization

Last Week in Pony - February 22, 2026

Crank up this week’s theme song — Horse Outside by the Rubberbandits — and settle in. Big week. We welcomed a new committer, shipped three brand-new libraries, and put out ten releases across five projects. There’s also a persistent HashMap bug fix that enabled json-ng to drop its custom null type, three new Pony patterns, and a blog post about teaching Claude to write Pony.
