+## v0.14.0 tagged
+
+Two features shipping. Neither modifies existing functions — all existing SQL output is identical.
+
+### 1. Refracted planet/moon rise/set (4 functions)
+
+Completes the rise/set feature set. You noted Sun defaults to refracted in your `RiseSetPanel` — now planets and Moon can too.
+
+```sql
+-- Planet: -0.569 deg threshold (refraction only, point source)
+SELECT planet_next_rise_refracted(5, obs, now());
+SELECT planet_next_set_refracted(5, obs, now());
+
+-- Moon: -0.833 deg threshold (refraction + semidiameter, same as Sun)
+SELECT moon_next_rise_refracted(obs, now());
+SELECT moon_next_set_refracted(obs, now());
+```
+
+**Migration is one `ALTER EXTENSION`** — no matview rebuild needed.
+
+**Threshold rationale:**
+- Planets are point sources. Even Jupiter at opposition subtends 24 arcsec (0.4 arcmin). Atmospheric refraction at the horizon is 34 arcmin. Semidiameter is negligible. So: refraction only = -0.569 deg.
+- Moon's mean semidiameter (15.5') is close enough to the Sun's (16') that the same -0.833 deg threshold applies. Error from using the mean: ~1 arcmin → ~15 seconds in time.
+
+**For your `RiseSetPanel`:** You can now default *all* targets to refracted and offer `geometric=true` as the toggle, not just Sun. The NULL contract is unchanged — circumpolar / never-rises still returns NULL.
+
+### 2. Constellation identification (2 functions)
+
+New capability. Roman (1987) IAU boundary lookup — "Jupiter is in Aries."
+
+```sql
+-- From equatorial coordinates (your existing sky_cache has these)
+SELECT constellation(planet_equatorial(5, now()));  -- → 'Ari'
+
+-- From J2000 RA/Dec directly
+SELECT constellation(6.7525, -16.716);  -- Sirius → 'CMa'
+```
+
+`IMMUTABLE PARALLEL SAFE`. Compiled-in 357 boundary segments from CDS VI/42. Precesses J2000 coordinates to B1875.0 internally (the epoch of the original IAU boundary definitions).
+
+**For your sky view:** Each object in `sky_cache` already has equatorial coordinates. One call per row gives the constellation label. Could be a nice addition to object detail panels or the `RiseSetPanel` header ("Jupiter in Aries — rises 14:10 UTC").
+
+### Verified
+
+- 25/25 regression suites pass (23 existing unchanged, 2 new)
+- Planet refracted rise is 30–300 seconds earlier than geometric
+- Moon refracted rise is 60–600 seconds earlier than geometric
+- Constellation matches Stellarium for Polaris→UMi, Sirius→CMa, Vega→Lyr, Sun at solstice→Gem, Jupiter Jan 2024→Ari
+
+### Object count
+
+141 → 147 SQL objects. All `PARALLEL SAFE`.
+
+---
+
+**Next steps for recipient:**
+- [ ] `ALTER EXTENSION pg_orrery UPDATE TO '0.14.0'` when ready
+- [ ] Consider defaulting all rise/set targets to refracted (not just Sun)
+- [ ] Consider adding constellation labels to sky objects
