Three bugs in FreeBSD's ig4 driver, one dead touchpad
A touchpad that died on every resume turned out not to be a suspend bug at all. FreeBSD never started the I2C controller the touchpad is wired to, for three separate reasons.

The Build Said Nothing
1.8.62 fixes fourteen things that never errored: pages dropped without a word, a 404 in the wrong language, a header that refused geolocation.
The Client Wants to Fix a Typo
1.8.60 is about the work an agency does between builds: letting a client fix their own headline, and a GTM install that was only ever half there.
The Paragraph You Clicked Is Not in the File
Click-to-edit is easy to build and hard to make safe. Here is the rule that decides which paragraph a click means, and why the editor sometimes refuses to guess.
What Breaks If I Change This?
We built an incremental build for 1.8.60. It made a five-thousand-page site five per cent faster. Here is why we shipped it anyway, and what it is actually for.
One Sitemap Per Site Does Not Scale to Forty Clients
An agency has a different relationship with sitemap.xml than a site owner. Split sitemaps answer 'is it indexed' per section, without forty dashboards.
The Build Was Green and the Site Was Wrong
Almost every fix in four releases came from one place: a third-party crawler, weeks after a build that reported success. What those failures had in common.
The Duplicate Pages Your Crawler Cannot See
A site audit finds copied pages by comparing words. The pages that actually compete with each other share an intent and almost no vocabulary, and word comparison is blind to them.
What's New in MDDB 2.14
MDDB 2.14 speaks the stateless MCP revision without dropping the old one, and fixes three ways retrieval was quietly returning the wrong document first.
Why Your RAG Returns the Wrong Document
A ten-document corpus, one ordinary question, and a semantic search that ranks the right answer nowhere. What actually fixed it was not a parameter.
Every January, Every Footer Is Wrong
A generator that reads the clock cannot promise the same bytes twice. Which is why the copyright year in your footer is a harder problem than it looks.
Flat Throughput Is a Diagnosis
Two optimisations to MDDB's vector loop predicted 33% and delivered 1.5%. The benchmark had been saying why for months, in a column nobody read as a diagnosis.
