Selected firmware inventory reaches record-level evidence closure
11 September 2026 · reference revision
Historical research revision: all 391 selected records now have source-bounded change or distribution evidence. 369 have supported dates; 22 factory-, physical-media-, launch-only or nonexistent public releases are explicitly marked not applicable instead of unresolved. PS4 1.50b and Portal 2.0.5/6.0.1 close the final genuine evidence gaps. This does not claim lifetime completeness or current download safety.
Final PS3 chronology cohort gains bounded evidence
11 September 2026 · reference revision

Disc-only 1.94 receives an availability bound; four other disc-only records retain unknown exact days. 381 of 391 records now have change evidence and 358 exact dates. No firmware binaries are hosted or recommended.
PSPgo chronology gains explicit model-specific evidence
11 September 2026 · reference revision
Historical research revision: nine PSPgo-compatible releases now have exact chronology dates and seven previously missing rows have notes. Factory firmware 5.70 receives a launch-hardware availability bound, while the 6.00 pre-launch announcement remains intentionally undated because the technical chronology says no PSPgo release existed. 372 of 391 records now have change evidence and 352 have exact dates.
Nineteen PSP firmware gaps gain source-bounded notes
11 September 2026 · reference revision
Historical research revision: nineteen PSP rows now have exact-version technical notes. Two exact dates and nine factory-, hardware- or UMD-distribution bounds were added without mislabeling non-OTA builds as public releases. 365 of 391 selected records now have change evidence and 343 have exact release dates. Not a new Sony release or installation recommendation.
Ten Portal release dates added
11 September 2026 · reference revision
Historical chronology revision: ten Portal versions from 2.0.6 through 7.0.2 now carry source-labelled rollout dates, including the delayed 3.0.0 release and explicit North America/Europe boundary for 4.0.0. Base version 2.0.0 receives only a retail-hardware availability bound; three minor versions remain date-unresolved. 341 of 391 selected records now have exact dates. Not a new Sony release or lifetime-completeness claim.
Final Vita cohort gains notes, dates and launch-build context
11 September 2026 · reference revision
Historical research revision: Vita 1.69.1 gains its Escape Plan compatibility note and date, withdrawn 1.65 gains release timing, and Sony’s cradle manual documents 1.50 support. Versions 1.04–1.06 now show qualified game-card or launch-hardware distribution bounds while retaining their unknown changelogs and public-release dates. 331 of 391 selected records now have exact dates and 346 have change evidence. Not a new Sony release or lifetime-completeness claim.
PS3 4.86 notes and four release dates added
11 September 2026 · reference revision

Exact dates were also added to versions 4.91 through 4.93 from a technical chronology while Sony remains the source for their notes. The remaining PS3 gaps now carry exact search outcomes rather than inferred claims. 329 of 391 selected records have exact dates and 344 have change evidence. Not a new Sony release or lifetime-completeness claim.
Twenty-one PS4 release dates added
11 September 2026 · reference revision
Historical chronology revision: twenty-one PS4 records from launch firmware 1.50 through version 13.52 now have exact dates. Sony’s North American launch statement resolves 1.50 after a conflicting chronology value was rejected. PS4 1.60 remains undated because Sony’s late-night schedule and a next-day chronology value do not establish one unqualified calendar date. 325 of 391 selected records now have exact dates. Not a new Sony release or lifetime-completeness claim.
Twenty-eight recent PS5 release dates added
11 September 2026 · reference revision
Historical chronology revision: exact dates are now attached to twenty-eight PS5 versions from 23.02-08.20.00 through 26.05-13.60.00.

11 September 2026 · reference revision

11 September 2026 · reference revision
