v2.15.0

Hello everyone!

Today, we’re excited to announce that Linkwarden is getting one of its largest mobile updates so far, along with a web app that’s much lighter to run.

For those who are new here, Linkwarden is a tool for collecting, organizing, reading, and preserving webpages, articles, and documents in one place. Linkwarden is available as a **[Cloud offering](https://linkwarden.app)**, or you can **[self-host](https://docs.linkwarden.app/self-hosting/installation)** it on your own server.

Let's get into it.

## What's new on mobile:

### 🖍️ Highlight and annotate

You can now highlight text in the reader view, pick from four colors, and attach a note to any highlight.

There's also a new Notes & Highlights view per article which lets you skim what you've marked and jump to it in the text.

### 📥 True offline mode

Previously, the app only saved preserved formats for links you had already opened. Now, you can turn on **Save for offline access** in the settings, and the app will download every preserved format in the background as you browse.

### 🪪 Link details sheet

Long-press any link to open Link Details, which shows all the information about a link in one sheet, similar to the web app.

### 📖 Customizable reader view

Adjust font, text size, line height, and background color as you read.

## What's new on the web:

### 🧠 Much lower memory usage

Linkwarden 2.15 roughly halves idle memory usage, from around 700 MB down to about 350 MB.

It's worth mentioning that after a heavy workload, memory may stay higher because the runtime keeps previously allocated memory ready for reuse. This is expected and is not a memory leak.

If you don't need webpage preservation, setting `DISABLE_BROWSER=true` skips that work entirely, keeping the instance right at the ~350 MB mark. Otherwise, for a leaner setup, you can use:

```
MALLOC_ARENA_MAX=2
NODE_OPTIONS=--max-old-space-size=400
ARCHIVE_TAKE_COUNT=1
```

These settings limit memory pools, cap the app's heap, and preserve one link at a time to keep spikes smaller.

### 🐳 A much smaller Docker image

The Docker image has also been cut in half, dropping from roughly 3.0 GB to 1.5 GB.

### 🔑 Generic OIDC provider

Self-hosters can now connect **any** OpenID Connect identity provider. Check it out in the [docs](https://docs.linkwarden.app/self-hosting/sso-oauth#generic-oidc)!

### 🔒 Increased security

A good chunk of this release went into security hardening. We **strongly** recommend updating to 2.15.

## There's more...

As always, there's a long tail of smaller improvements across the web and the mobile app.
