Update Notice: - You may delete file named icudt*.dat inside program folder when updating from old releases. * Notice: From now on, UXP rev will point to `custom` branch of my UXP repo instead of MCP UXP repo, while "official UXP changes" shows only `tracking` branch changes.

Another update (sorry...) to yt-dlp for Vista, now made with the new and shiny Python 3.13.7 from adang1345. Link.

New build of post-deprecated Serpent/moebius for XP! * Notice: This repo will not be built on regular schedule, and changes are experimental as usual. ** Current moebius patch level should be on par with 52.9, but some security patches can not be applied/ported due to source milestone differences between versions.

Totally agree ... except for one detail, i'm actually unemployed, with no income at all (and cannot find any job compatible with my actual health problems, other than the fact that here none hire a 55 years old man, even if when i had a job, i was an electronic technician, repairer, installer, and prototyper) My actual machine is a third hand ex-gaming laptop i had the luck to find for 300 Euro from a friend that changed its own almost 10 years ago, it's still a perfectly working machine, and i don't have any intention to change it, nor for discourse idi*ts, nor for any other reason. Almost not needed to say, my cellphone is an old Samsung running android 9 , still working and that i had for free also this one years ago (so i changed my old still working Nokia 5800XM ) I know that some peoples have a "psychosis" that make them change their devices each time one new pops out, but i just cannot understand them.

@Reino I Tried libcrypto-3.dll and libssl-3.dll 3.5.0 and 3.5.2 with Pop Peeper and they works perfectly under XP. Pop Peeper itself is fully compatible with XP but since release 5.5, it use the official OpenSSL libraries for TLS 1.3 that are not compatibles with XP. Regards

... I'm sorry I have to say this , but once the hack currently implemented by upstream stops working (and it will stop ), for XP/Vista[/Win7] users, for which the scheduled workaround, deno, isn't compatible, "Apple-device" (iOS+web_safari) type of YouTube (HLS) streams will be the ONLY accessible options, at least until Google restricts them further with a POT implementation; the log below was generated with yesterday's Vista build of yours , it provides a glimpse of how things would look when "the hack" has been broken and the deno-enabling PR merged: yt-dlp_x86 --extractor-args "youtube:player_client=ios,web_safari" -vF "O5TS2CbBhKo" [debug] Command-line config: ['--extractor-args', 'youtube:player_client=ios,web_safari', '-vF', 'O5TS2CbBhKo'] [debug] Encodings: locale cp1253, fs utf-8, pref cp1253, out utf-8 (No VT), error utf-8 (No VT), screen utf-8 (No VT) [debug] yt-dlp version local@2025.09.25 [4429fd045] (win_x86_exe) [debug] Python 3.11.9 (CPython x86 32bit) - Windows-Vista-6.0.6003-SP2 (OpenSSL 3.5.2 5 Aug 2025) [debug] exe versions: none [debug] Optional libraries: Cryptodome-3.23.0, brotli-1.1.0, certifi-2025.08.03, mutagen-1.47.0, requests-2.32.5, sqlite3-3.45.1, urllib3-2.5.0, websockets-15.0.1 [debug] Proxy map: {} [debug] Request Handlers: urllib, requests, websockets [debug] Plugin directories: none [debug] Loaded 1833 extractors [debug] [youtube] [pot] PO Token Providers: none [debug] [youtube] [pot] PO Token Cache Providers: memory [debug] [youtube] [pot] PO Token Cache Spec Providers: webpo [youtube] Extracting URL: O5TS2CbBhKo [youtube] O5TS2CbBhKo: Downloading webpage [debug] [youtube] Forcing "main" player JS variant for player 0004de42 original url = /s/player/a61444a1/player_ias.vflset/en_US/base.js [youtube] O5TS2CbBhKo: Downloading ios player API JSON [youtube] O5TS2CbBhKo: Downloading web safari player API JSON [debug] [youtube] O5TS2CbBhKo: ios client https formats require a GVS PO Token which was not provided.

Best wishes!
