 ## Unreleased
 
+## 1.11.0 — 2026-07-27
+
+### Added
+- **Pool naming convention `Title (YYYY).ext`** (`src/core/naming.py`). Pooled
+  movies now carry a four-digit year in parentheses, so two same-named films
+  coexist and the filename is self-describing.
+  - **Import requires a year**: the import dialog has a per-row **Rok** field
+    (pre-filled from the source filename), and *"Najít ČSFD odkazy"* now also
+    fills the year from the top ČSFD hit — a **suggested** year is tinted **blue**
+    (verify it), a name **colliding** with the pool stays **red**. The import is
+    blocked until every row has a four-digit year, and the file lands in the pool
+    as `Title (rok).ext`. Same title + different year no longer collide.
+  - **Rename to the convention**: *Filmy → "Přejmenovat dle ČSFD (rok)…"*
+    (`FileManager.rename_all_to_canonical`) renames selected movies (or the whole
+    pool) to `Title (rok).ext` using the year from their ČSFD metadata, with a
+    cancelable progress dialog; files with no known year are skipped and name
+    collisions reported. `File.title` keeps the clean title (without the year);
+    `File.name_context` recovers the year from a canonical filename when no
+    ČSFD/tag year exists.
+
+### Changed
+- **Filmotéka hardlinks are named by the clean title (no year).** In the tag
+  tree a movie now links as `Title.ext` instead of the pooled `Title (YYYY).ext`.
+  When two *different* films would collide on that name in the **same folder**,
+  the colliding ones keep the year (`Title (YYYY).ext`) to tell them apart; a
+  residual clash (same title *and* year) gets a stable numeric suffix. Copy-as-is
+  mirrors (Seriály) are untouched — they stay 1:1. A per-category
+  `filename_template` (Tag schéma dialog) still overrides the default inside its
+  folders. Link creation and obsolete-detection now share one collision-resolved
+  plan (`HardlinkManager._plan_links`), so they can't disagree on a name — the
+  first generation after upgrading re-lays the affected links once, then it is
+  stable.
+- `File.name_context`'s `year` field is now always a string (was an int when it
+  came straight from the ČSFD cache) — uniform for filename templates.
