chore: release v0.24.5

A saved band selection outlives the code that made it. 12 m was removed from the
watched set, but every operator who had already enabled the watch kept
subscribing to it — paying for a firehose whose messages the detector then threw
away. The stored list is filtered against the offered one now.

The badge appeared on the next poll rather than on the event, up to twenty
seconds after the announcement, so the two read as unrelated things that happened
to mention the same band. It appears immediately.

And the toast is gone. It said the same thing as the badge and vanished after
five seconds — an operator who was tuning when it passed had no way back to it,
which is precisely what the badge was built to fix. Keeping both announced an
opening twice and still lost it once.

+      "Shared CAT is steadier and now diagnoses itself. It survives a rig answering \"busy\" just after transmit instead of dropping the link, stops repeating a PTT state the client never changed, and logs a plain explanation when another program has taken its port or when a client is set to a rig model instead of Hamlib NET rigctl. It also answers the lock-mode and stop-morse commands some clients send around every transmit, instead of refusing them.",

+      "Band-opening detection now works on the bands it was meant for. Switching on \"Watch for band openings\" (Settings › DX Cluster) subscribes to the PSK Reporter feed and adds the two RBN nodes it needs — it was reading a handful of VHF cluster spots while thousands of stations were reporting. It watches 10, 6, 4 and 2 m, counts only reports collected within 300 km of you so an opening means an opening HERE, no longer throws away paths beyond 2400 km, and looks for the busiest direction instead of demanding that every station heard sit in one sector. An opening under way shows as a blinking badge beside the clock the moment it is found — band, direction and typical distance, with a mark when it is unusual for the season — and stays until the band goes quiet, and the direction it names is right — a sector crossing north used to be announced as its opposite.",
+      "Test connection now actually tests. Club Log checked that the three fields were not empty and reported success without contacting anyone, so a wrong password looked exactly like a right one; it now signs in for real, through the read-only endpoint so a test can never add a record. LoTW reports its two credentials separately: TQSL signs uploads and never uses the website password, so a wrong one used to break nothing until the day confirmations were downloaded.",
+      "The Ultrabeam / SteppIR widget in Station Control can now drive the antenna, not just describe it: a button per configured band tunes it there, up and down move it 25 kHz at a time, and tracking can be switched on or off with its 25 / 50 / 100 kHz threshold beside it. The band you are on lights up, and the commanded frequency is shown in the header.",
+      "The QSO filter can express a real question. Every condition was joined by one global AND or OR, so \"2 m or 70 cm, in FT8, since January\" had no form: AND killed the two bands, OR let every FT8 QSO through. Two operators — is one of / is none of — take a comma-separated list, so the OR sits inside one condition and the rest keeps ANDing.",
+      "Split works properly on a Kenwood. Split Operating: Rig in WSJT-X and JTDX did nothing at all through the shared CAT — OpsLog answered \"done\" to both split commands and left the radio on the receive frequency, so on a pileup you transmitted straight onto the DX while the software showed exactly what you had asked for. A radio whose backend cannot set split now refuses, so WSJT-X says so and you can switch to Fake It. And the two frequencies no longer swap the moment you key up: the rig reports the VFO in use, which is the receive one on receive and the transmit one on transmit, and that decided which frequency a split QSO was logged on."

Elle surveille le 10, 6, 4 et 2 m, ne retient que les reports collectés à moins de 300 km de toi pour qu une ouverture veuille dire une ouverture ICI, ne jette plus les chemins au-delà de 2400 km, et cherche la direction la plus dense au lieu d exiger que toutes les stations entendues soient dans un même secteur. Une ouverture en cours s affiche en pastille clignotante à côté de l heure dès qu elle est détectée — bande, direction et distance typique, avec une marque si elle est inhabituelle pour la saison — et y reste jusqu à ce que la bande se taise, et la direction annoncée est juste — un secteur traversant le nord était auparavant annoncé à l opposé.",

LoTW annonce ses deux identifiants séparément : TQSL signe les envois et n utilise jamais le mot de passe du site, donc un mauvais ne cassait rien jusqu au jour du téléchargement des confirmations.",

La bande courante s allume, et la fréquence commandée s affiche dans l en-tête.",
+      "Le filtre des QSO sait exprimer une vraie question. Toutes les conditions étaient jointes par un seul ET ou OU global, donc « 2 m ou 70 cm, en FT8, depuis janvier » n avait aucune forme : le ET tuait les deux bandes, le OU laissait passer tous les QSO FT8. Deux opérateurs — est parmi / n est pas parmi — acceptent une liste séparée par des virgules, le OU tient donc dans une seule condition et le reste continue de se combiner en ET.",

Split Operating: Rig dans WSJT-X et JTDX ne faisait rien du tout via le CAT partagé — OpsLog répondait « fait » aux deux commandes et laissait la radio sur la fréquence de réception, donc sur un pileup tu émettais en plein sur le DX pendant que le logiciel affichait exactement ce que tu avais demandé. Une radio dont le backend ne sait pas régler le split refuse désormais, WSJT-X le dit et tu peux passer en Fake It. Et les deux fréquences ne s inversent plus dès le passage en émission : le rig annonce le VFO en service, celui de réception à l écoute et celui d émission en émission, ce qui décidait sur quelle fréquence un QSO en split était enregistré."

The amp pushes status frames on the same socket it answers commands on, and it pushes them constantly once in OPERATE; OpsLog read one line per command and took whatever arrived first as its answer, so the stream slipped permanently one reply behind until a command timed out and the connection was dropped. Replies are now matched to the command that asked for them. Only ever visible over a remote link with the amplifier in OPERATE.",

Whether a grid counts as new follows the group digital modes setting — with it on, a square worked on FT8 is no longer new on FT4; with it off the two are separate.

Le panneau de filtres a été remis d aplomb selon une seule règle : un interrupteur est un comportement qu on active ou non, les pastilles choisissent dans un ensemble.

Et quand le programme en cours d'exécution ne peut pas être renommé du tout, ce que certaines protections empêchent volontairement, OpsLog n'abandonne plus : il laisse la nouvelle version à côté de l'ancienne et les échange après sa fermeture, quand son propre fichier redevient un fichier ordinaire.

+// spots the band-opening detector already eats.
+//
+// Why this exists at all: the detector was fed from the DX cluster and the RBN,
+// and on VHF that is a few hundred skimmers, nearly all of them on HF. A 6 m
+// opening carrying 869 stations reached OpsLog as a handful of spots, or none.
+// PSK Reporter is every ordinary station running WSJT-X and reporting what it
+// decodes — the difference is two orders of magnitude, not a threshold.
+//
+// The feed's shape happens to suit us exactly:
+//
+//	topic   pskr/filter/v2/<band>/<mode>/<tx call>/<rx call>/...
+//	payload {"f":50313000,"md":"FT8","rp":-12,"sc":"F4BPO","sl":"JN36",
+//	         "rc":"OH5CX","rl":"KP30","b":"6m"}
+//
+// BOTH grids are in the message, so distance and bearing are arithmetic. No
+// lookup, no DXCC-centre approximation, no extra network call — which is what
+// made the cluster path's bearings coarse.
+//
+// Volume is the real design constraint. Six metres open is thousands of
+// messages a minute, and OpsLog runs on some very old PCs. So: no history is
+// kept here, nothing is persisted, each message is parsed and handed on or
+// dropped, and the callback does the deciding.
