1.5.0

Added

• Cressi BLE support (characteristic read ioctl, vendor service preference, synchronous characteristic reads)
• Halcyon Symbios and Seac serial service registration
• onLog sink (LogEvent) so host apps can forward library diagnostics
• Selectable computer model IDs
• Peripheral-ready state exposed to callers

Fixed

• Auto-reconnect no longer blocks the main thread (openBLEDevice was hanging the UI for 2+ seconds)
• BLE I/O robustness for uwatec_smart/Scubapro Aladin downloads (per-characteristic write type, working read-timeout wiring, write flow-control)
• Double-free in ble_stream_close (#17)
• Time-weighted average depth calculation
• Shearwater Peregrine tx import, device fingerprint, and GPS handling
• Fingerprint handling across device models

Changed

• Synced libdivecomputer to upstream HEAD: adopted DC_SAMPLE_LOCATION (replaces DC_FIELD_LOCATION) for multi-point GPS during a dive; picked up descriptor/parser updates for mares_iconhd, halcyon_symbios, hw_ostc, seac, suunto, divesoft, deepsix, usb/usbhid
• Shearwater model detection now reads via ID_MODEL with GNSS-status GPS detection
