NOOP v11.0.0

A major release, and the version number is about one thing above all: the WHOOP 5.0 and MG finally hold
a connection. Everything else — a body clock on the Sleep screen, nights that read straighter, a Journal
that stops counting silence against you — arrived alongside it.

The WHOOP 5.0 / MG connection

A handshake the strap never answers no longer takes the link with it (#1635, #1642, thanks
@Zebsi235). NOOP wrote a CLIENT_HELLO on every connect and the 5/MG never acknowledged it; roughly
4.8 seconds later the link dropped, and the cycle repeated all day. NOOP now recognises the pattern,
stops writing the handshake for that strap, and keeps the link — the "Live HR, not fully paired" state
the app already modelled, reached deliberately instead of never. A field capture confirmed a link held
for over seven hours where it previously lasted five seconds.

An HCI capture contributed by @Zebsi235 settled what the strap is actually doing: it answers the
pairing request with Pairing Not Supported. That is a refusal, not a timing problem, and it ended
weeks of guessing.

Reconnecting costs what it should (#1778, #1779, #1781). Tapping Connect used to throw away
everything NOOP had learned and re-earn it over five more dropped links. It now keeps that knowledge,
gives the handshake exactly one fresh attempt, and settles after a single reconnect. A timer firing is
no longer treated as you asking to try again.

The strap is asked properly, and says so in the log (#1639, #1646, #1648, #1652, #1653, #1656,
#1668). NOOP now observes the OS pairing flow rather than inferring it, reads the Device Information
Service on a strap that never bonds, enumerates what a strap actually offers once per device, and lets
a 5/MG identify itself instead of being guessed at from its serial.

Clearing a stale phone pairing (#1790). When the phone holds a pairing the strap no longer honours,
NOOP can now clear it for you — off by default, in Test Centre, once per streak, and only after the
guide has already asked you to do it by hand.

Sleep

Your body clock (#1722, #1723, #1726, #1729, #1731, #1733). A 24-hour dial on the Sleep screen
showing your circadian phase, with an absolute chronotype bucketed from it. The diagnostics report the
inputs it used, and a rhythm too small to be real is refused rather than drawn.

A partial night is not a whole one (#1717, #1721, #1734). A hypnogram that only partly downloaded
was scored as though complete, which quietly shortened nights after an interrupted sync. Both readers
of that coverage now agree on what "complete" means.

Fragmented nights are stitched back together (#1755, #1782). When data is sparse, NOOP bridges
short gaps between sleep runs — and now allows a longer interruption when your heart rate stayed in the
sleep band throughout, because on a strap with no motion data heart rate is the better witness.

Sleep debt you can act on (#1741). Debt is now expressed as a target for tonight rather than an
abstract ledger.

Journal, workouts and metrics

Yes days are compared against No days (#322). Previously an insight weighed the days you logged
against every day you did not — so a week you never opened the app counted as a week of No.

Pause and resume a live workout (#1690). The controls are on the active-workout card, and the five
clocks that used to ignore a pause now honour it.

Latest Workouts opens a session (#1701, #1703). Tapping a row goes to its detail, and iOS uses the
same 14-day window Android already did.

Skin temperature leads with the absolute (#1663, #1665, #1671, #1708). The nightly absolute is
stored and shown first, deviation beneath it, in your own units throughout.

VO₂max says why a line breaks (#1740). The chart shows the decimal it draws, and explains a gap
rather than leaving one.

Straps, sync and privacy

Multiple straps are kept apart (#1455, #1634, #1730, #1745). Physiology is read across every
registered strap, firmware is attributed to the strap it came from rather than the last to connect,
last-sync belongs to a strap rather than the install, and a 5/MG carries a stable identity derived from
its serial.

Health Connect permissions by category (#1509, thanks @kavemang). Recovery and wellness, Activity,
and Body composition are picked before Android's prompt. Existing installs are detected and keep every
category they already had.

A crash you can report (#1718, #1720, #1724). Android shows a copyable recovery screen after a
crash, redacted everywhere it leaves the device — and an upgrade no longer greets you with a crash from
the build it replaced.

Update checking, on by default (#1674, #1675). Both platforms notice a new release. The privacy
documentation now describes what actually happens.

Experimental self-hosted push (#1631, #1700). One-way push to your own endpoint, off by default,
with the destination errors localized.

Oura

A bonded ring with no advertised name is listed again (#1776, thanks @pipiche38). A bonded ring
often stops advertising a name, and that was exactly the ring the Add-Device screen could not show.

Skin Temp as a Key Metrics tile (#1678), and protocol corrections (#1629, #1687, #1777).

Under the hood

Raw 100 Hz IMU capture and labeled recording sessions for the 5/MG (#1709). A JSON query CLI for the
local read tools (#1752). Analysis reads each row once instead of 2.25 times (#1695, #1696). Swift
analytics tests run on Linux (#1529). Several diagnostics now say which gate refused a metric, rather
than leaving a blank.

Thanks to @bhelm, @pipiche38, @kvnloo, @Zebsi235, @kavemang, @fadkeprasad, @Meriquium and @dwehrmann
for contributions in this release.
