+## v0.11.0 tagged
+
+```bash
+git pull origin main
+# or: git checkout v0.11.0
+```
+
+Tag `v0.11.0` is on `main`. Your production deployment is already running the same code — this just makes the release official.
+
+Glad to see zero NULL RA/Dec across all object categories. That was the target.
+
+## v0.12.0 roadmap — what's coming
+
+Based on your asks and our backlog, v0.12.0 will focus on:
+
+### 1. Equatorial GiST index
+
+Your proximity query currently runs Python-side Vincenty over `whats_up` results. v0.12.0 adds a GiST operator class for `equatorial`, enabling:
+
+```sql
+-- Index-accelerated cone search
+CREATE INDEX idx_sky_radec ON sky_cache USING gist (eq);
+
+SELECT * FROM sky_cache
+WHERE eq_within_cone(eq, planet_equatorial_apparent(5, NOW()), 15.0);
+```
+
+The `<->` operator already works for ad-hoc angular distance. The GiST index makes it efficient at scale.
+
+### 2. Saturn/Uranus/Mars moon observe functions
+
+You noted these moon families have equatorial but no topocentric. v0.12.0 adds `_observe()` variants for all three:
+
+- `saturn_moon_observe(int4, observer, timestamptz)` → topocentric
+- `uranus_moon_observe(int4, observer, timestamptz)` → topocentric (already exists from v0.2.0)
+- `mars_moon_observe(int4, observer, timestamptz)` → topocentric
+
+These follow the same pattern as `galilean_observe()`.
+
+Note: `uranus_moon_observe()` and `mars_moon_observe()` already exist (they were in v0.2.0). Saturn moon observe might also already be there — will confirm. If all observe functions exist, this item just becomes integration guidance.
+
+### 3. Additional items under consideration
+
+- Nutation (IAU 2000B) — narrows the gap with Skyfield/Horizons from ~1 arcsec to ~0.1 arcsec
+- Neptune moon (Triton) — single moon, straightforward addition
+
+We'll send specifics once the plan is finalized.
+
+---
+
+**Next steps for recipient:**
+- [ ] Verify `v0.11.0` tag matches your deployed code (should be identical)
+- [ ] Let us know priority ordering: GiST index vs Saturn/Uranus/Mars observe vs nutation
+- [ ] If you have specific cone search radii or catalog sizes, share them — helps tune the GiST strategy
