Synology: Huge Docker Container Updates July 2026

Synology Huge Docker Container Updates July 2026

July 2026 has delivered another wave of major updates for the self-hosting community. Let’s start with the biggest news for Synology users: DSM 7.4.1 is now available. Synology released DSM 7.4.1-90080 on July 23, 2026. This is a stability-focused point release that mainly fixes an issue where a USB UPS could not be recognized after updating to DSM 7.4, and another where USB devices could not be used on certain models. As always, the update restarts the NAS and you cannot downgrade afterward. Many older models still receive it (though some will remain on their last suitable version). Full details and the manual update guide are already live on the site.

Immich 3 landed at the beginning of the month (v3.0.0 on July 1, with subsequent 3.0.x and 3.1.0 releases). This is a substantial major version. Highlights include mobile non-destructive editing (crop, rotate and adjust without touching the original file, fully synced with the web editor), a first preview of Workflows (drag-and-drop automation with triggers, filters and actions), much more reliable background backup on Android and iOS, a new “Recently Added” page, integrity checks that compare filesystem vs database, slideshow on mobile, experimental real-time HLS video transcoding, a new web video player, OCR on mobile, and various performance and UX improvements. There are breaking changes (mostly API-related for third-party tools), so check the official migration guide before updating. My Immich guides for Synology and UGREEN have been refreshed accordingly.

Paperless-ngx 3 followed later in the month (v3.0.0 on July 22, already up to 3.0.4). This is one of the biggest releases in the project’s history. Notable additions: a new Tantivy search backend replacing Whoosh, document file versions, share-link bundles, a document parser plugin framework, and Paperless AI (local or remote LLM features) plus remote OCR via Azure AI. There are several breaking changes: PAPERLESS_SECRET_KEY is now mandatory, document/thumbnail encryption support is removed (decrypt first), consumer and OCR settings have been reworked, older API versions and Python 3.10 are dropped, and duplicate handling defaults have changed. The Paperless-ngx guides on mariushosting for Synology and UGREEN have been updated.

Jellyfin went through significant internal changes. Project leader Joshua Boniface stepped down (effective July 19), citing severe burnout after more than seven years. Long-time core team member Anthony Lavado also left for personal priorities, and co-founder Andrew Rabert departed a few days earlier, moving his desktop client work outside the official organization (now continuing independently). The departures were described as amicable. The remaining team continues day-to-day development; RC work on the 12.0 series is progressing and infrastructure is still being handled by familiar hands. Jellyfin is not disappearing and is not changing its free, non-monetized direction. It remains an excellent fully self-hosted alternative with free hardware transcoding. My guides for Jellyfin for Synology and UGREEN stay current.

On mariushosting, every article and guide continues to be kept rigorously up to date with real-world testing. No stale screenshots, no outdated compose files, no “it used to work” excuses. When a major container or DSM update lands, the relevant guides are revised promptly so you can follow them with confidence.

Codeberg has drawn a clear line: after a community vote (358 in favor, 144 against), the platform now prohibits projects that “mostly consist of code written by generative AI tools” (vibe-coded projects). The change targets repositories that are largely AI-generated with little human maintenance, citing resource costs, unclear copyright, and the desire to keep the forge focused on genuine human collaboration. Existing projects with real history and active communities are not being mass-deleted; enforcement is case-by-case. Codeberg also reaffirmed it will never train AI models on hosted code or user data.

🔥Meanwhile, a fierce, relentless heatwave has been sweeping across Europe. Scorching days, tropical nights, record-breaking temperatures that turn the air into a heavy, shimmering veil, the kind of heat that presses on the chest and makes every movement feel slower. Romania has not been spared; the great heat arrived and settled in, turning ordinary days into a test of endurance. For those who have not been following me closely: I have been dealing with 🩸blood-pressure problems, and everything started precisely with the arrival of this intense heat. You can read more on my personal blog.

For the curious: Synology has not sent me any products for review in 4 years and has been ghosting me completely. UGREEN did the same with the new GT series. Marius is being ignored by the big brands, but that does not discourage me. What really hurts, though, is something else. Every single week I receive dozens of emails. People ask for help with Docker stacks that refuse to start, with Immich migrations that go wrong, with Paperless-ngx that won’t OCR, with reverse proxies, with permissions, with hardware transcoding and I answer. I spend hours writing detailed replies, testing on my own machines, sending corrected compose files, explaining step by step. Many of you write back saying “thank you, it finally works” or “you saved my weekend”. And then, silence. When it comes to supporting Marius at mariushosting that made all of this possible, most of those same people simply disappear. 🎗️This is a blog that lives only on donations. No ads, no sponsors, no affiliate links, no paid memberships, no corporations. Just me, the electricity, the hardware, the time, and the will to keep every single guide up to date. If you enjoy the content, Support My Work. Recently, I also added WISE as an alternative method to support me. Now you can support me via PayPal, Stripe and WISE. Thank you to everyone who continues to support the blog.

Despite the heat and the personal challenges, the passion for clean, independent, carefully tested guides remains the same. New articles are already in production. Below you will find the most recent guides updated in July 2026. See you in the next August update.
