Here's what's changed, what to check before switching, and how to fix the most common new errors. The most notable update in this release is that the features that produce accessible PDFs are ready to use in production workflows, and have graduated from the prototype phase. This update also gives you access to new and updated TeX-related programs, fonts, and macro packages. This blog post covers all the key information and important changes you need to know about.

Overleaf releases an official update once a year after rigorous testing to ensure everything works as expected. We do this in order to ensure a consistent and stable experience for the millions of Overleaf users, and ensure our support team is able to assist you with any issues or questions.

A recap of our virtual fireside chat, "AI Uncorked: Guardrails, Compliance & IP Protection for the Enterprise," held July 23, 2026.

When we polled the audience at the start of AI Uncorked, the results told a familiar story: 32% of organizations are just getting started with AI, another 32% are piloting in select teams, and only 21% say AI is established in how they work. Most enterprises, in other words, are somewhere in the messy middle — past curiosity, short of confidence. And the thing standing between the two, the panel argued, isn't the technology. It's governance.

That was the thread running through the entire conversation. Hosted by John Lees-Miller, co-founder of Overleaf, the fireside chat brought together Dr. Mark Bloomfield, Fellow at Cambridge Judge Business School, who spends most of his week advising boards on AI transformation, and Maximilian Freier, economist and Secretary of the Monetary Policy Committee at the European Central Bank, where he also coordinates the ECB's own AI rollout.

Here's what stood out from an hour of genuinely unscripted discussion.

We are pleased to announce Overleaf Server Pro 6.2.1! This release includes new features, bug fixes, and updates to the base image and installed packages, as well as internal dependencies. You can read the full release notes here.

Overleaf AI is now included in all Overleaf plans at no extra cost, with usage allowances and features varying by plan type. We’re also introducing Commons AI as a new option to increase the Overleaf AI allowance for campus-wide subscriptions.

This is because our most recent product survey indicates that 81.6% of you use AI in your research work or studies, and 60% use AI for LaTeX support. So now that assistance is available inside Overleaf: no context or window switching and with custom prompts tailored to research and technical writing.

This post breaks down exactly what's available on each plan, what the daily allowances mean in practice, and what's different for universities with the introduction of Commons AI.

With the release of TeX Live 2025 from the LaTeX Tagging Project team, you can use LaTeX to generate tagged PDFs that are accessible. This is important if you’re at a university or government agency, where you may be required to create accessible documents. This is because two pieces of legislation—the European Accessibility Act (EAA), which became effective in June 2025, and the ADA Title II Update, which goes into effect April 2026—are making this a legal requirement. This requirement includes a lot of the content that is produced in Overleaf.

The LaTeX Tagging Project is specifically designed to produce the structural tags required by PDF/UA-1 (and the upcoming PDF/UA-2). If a user follows the LaTeX Project's current tagging recommendations, they are effectively building a document that is "PDF/UA-ready," which is the strongest way to meet the WCAG 2.1 AA legal mandate required by US and European legislation.
