Jellyfin vs Double: at a glance
What is Jellyfin?
Seven candidates in, 12.0 is still trading features for correctness in the metadata layer.
RC7 continues the pattern the 12.0 train set: twelve changes, nearly all in the library and metadata layer, and none adding surface. The substantive ones tighten access control — search candidates are now filtered by user access in a single query, and permissions are enforced on similar-items lookups — alongside episode and season counting fixes for virtual items, anime provider IDs on season folders, and progress logging for data migrations. The release still restates the versioning change introduced at RC1, where the leading 10. was dropped so 10.11.x becomes 12.x, and still requires 10.10.7 or 10.11.x as an upgrade floor.
What is Double?
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.

Jellyfin
5.0COLLAB
Seven candidates in, 12.0 is still trading features for correctness in the metadata layer.
◆ Current state
RC7 continues the pattern the 12.0 train set: twelve changes, nearly all in the library and metadata layer, and none adding surface. The substantive ones tighten access control — search candidates are now filtered by user access in a single query, and permissions are enforced on similar-items lookups — alongside episode and season counting fixes for virtual items, anime provider IDs on season folders, and progress logging for data migrations. The release still restates the versioning change introduced at RC1, where the leading 10. was dropped so 10.11.x becomes 12.x, and still requires 10.10.7 or 10.11.x as an upgrade floor.
◆ Where it's heading
The stated goal of 12.0 has been to polish the backend rewrite that shipped in 10.11.0, and seven candidates in, that is still what the changes are. What has shifted subtly across RC5 to RC7 is the kind of correction: earlier rounds were query-cost work such as SQLite caching and batched lookups, while RC7 pairs performance with access enforcement, folding permission checks into the same queries rather than filtering afterwards. That combination usually appears when a rewrite is being audited rather than extended.
◆ Prediction
The change count per candidate is falling and the remaining work is concentrated in one contributor's metadata fixes, which points to 12.0 going final rather than to an RC8 carrying anything new. Nothing in this feed indicates when.
Double
8.8COLLAB
Double turns a recorded Chrome session into an agent that repeats the task.
◆ Current state
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
◆ Where it's heading
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
◆ Prediction
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
