v2.26.7: fix health check SDR detection on macOS (#188)

timeout (GNU coreutils) is not available on macOS, causing rtl_test to
silently fail and report no SDR device found. Now tries timeout, then
gtimeout (Homebrew coreutils), then falls back to background process
with manual kill.

+## [2.26.7] - 2026-03-14
+
+### Fixed
+- **Health check SDR detection on macOS** — `timeout` (GNU coreutils) is not available on macOS, causing `rtl_test` to silently fail and report "No RTL-SDR device found" even when one is connected. Now tries `timeout`, then `gtimeout` (Homebrew coreutils), then falls back to a background process with manual kill. (#188)
+
+---
+
+## [2.26.6] - 2026-03-14
+
+### Fixed
+- **Oversized branded 'i' logo on dashboards** — `.logo span { display: inline }` in dashboard CSS had higher specificity (0,1,1) than `.brand-i { display: inline-block }` (0,1,0), forcing the branded "i" SVG to render as inline which ignores width/height. Added `.logo .brand-i` selector (0,2,0) to retain `inline-block` display. (#189)
+
+---
+
+## [2.26.5] - 2026-03-14
+
+### Fixed
+- **Database errors crash entire UI** — `get_setting()` now catches `sqlite3.OperationalError` and returns the default value instead of propagating the exception. Previously, if the database was inaccessible (e.g. root-owned `instance/` directory from running with `sudo`), the `inject_offline_settings` context processor would crash every page render with a 500 Internal Server Error. (#190)
+
+---
+
+## [2.26.4] - 2026-03-14
+
+### Fixed
+- **Environment Configurator crash** — `read_env_var()` crashed with "Setup failed at line 2333" when `.env` existed but didn't contain the variable being looked up. `grep` returned exit code 1 (no match), which `pipefail` propagated and `set -e` turned into a fatal error. Fixed by appending `|| true` to the pipeline. (#191)
+
+---
+
+## [2.26.3] - 2026-03-13
+
+### Fixed
+- **SatDump AVX2 crash** — SatDump now compiles with `-march=x86-64` on x86_64 platforms (Docker and `setup.sh`), preventing "Illegal instruction" crashes on CPUs without AVX2. SIMD plugins still use runtime detection for acceleration on capable hardware. (#185)
+
+---
+
+## [2.26.2] - 2026-03-13
+
+### Fixed
+- **Docker startup crash** — `.dockerignore` excluded the entire `data/` directory, which is now a Python package (`data.oui`, `data.patterns`, `data.satellites`). Caused `ModuleNotFoundError: No module named 'data.oui'` on container startup. Fixed by only excluding non-code files from `data/`.
+
+---
+
+## [2.26.1] - 2026-03-13
+
+### Fixed
+- **Default admin credentials** — Default `ADMIN_PASSWORD` changed from empty string to `admin`, matching the README documentation (`admin:admin`)
+- **Config credential sync** — Admin password changes in `config.py` or via `INTERCEPT_ADMIN_PASSWORD` env var now sync to the database on restart, without needing to delete the DB
+
+---
+
 ## [2.26.0] - 2026-03-13
 
 ### Fixed
