After upgrading to the most recent firmware, the camera (DS-2CD2387G2-LU) stop answering all ISAPI calls. I checked and double checked that the web authentication was set to digest/basic, and it was. After downgrading to 5.7.11 build 221009 the ISAPI functions came back on. So either there is major bug in the most recent firmware or there is some new function hidden in one of the menus, which most be enabled for the ISAPI to work.
No ISAPI with firmware 5.7.12_221201

We have seen other cameras lose API functionality (intentionally) or it got moved around with an update.
You really need to be asking yourself why are you updating? If it is just for grins and giggles or OCD behavior to be running the latest firmware, think twice.
A common theme around here is don't fix what ain't broke. If the unit is working and meets your needs, in many instances an update breaks what you had working and provides you with something you didn't need or bricks the camera. In most instances, updates are simply security vulnerability patches (usually years after the breach was found), but since we do not give our cameras internet access, the update is useless to us.
Unless the release notes specifically mention it fixing a problem you are experiencing, more than likely it won't fix an issue and may make the camera worse by removing functionality.
Here are issues I have seen people report here where they were upgrading just for the sake of upgrading:

Here are issues I have seen people report here where they were upgrading just for the sake of upgrading:
- Dahua 5241E-Z12E that someone updated and then constantly reboots.
- Dahua 49225 and 49425 PTZ that Dahua intentionally removed autotracking with an update to force people to buy the more expensive PTZ.
- Hikvision DS-2DEA425IW-DW PTZ that Hikvision intentionally removed autotracking with an update to force people to buy the more expensive PTZ (*V5.7.3 220315 -Remove auto-tracking functions on DE4A).
- Hikvision ANPR camera losing half the FPS and loses the ability to read US plates - those are big deals to have happen, especially if you live in the USA.
- Hikvision ANPR DS-2CD4A26FWD camera that lost all ability to read plates - kinda makes a plate reader camera useless.
- Hikvision camera that the user lost ability to control the LED light function at night.
- Hikvision DS-7616NI-Q2 NVR that has the APIs changed. This is a big deal if you run automation.
- Hikvision wifi camera that loses the ability to use wifi after a firmware update and was intentionally removed due to too many complaints that the camera was dropping signal.
- DH-DB61 Doorbell that loses API functionality. A big deal for someone with automation.
- Hikvision iVM4200 v3.8 - loses the free ability to use the computer as storage and now need to subscribe.
- Dahua IPC-HFW1320S that started phoning home using 60MB/hr and costing someone thousands of dollars in data overages when he got his next mobile bill.
- Dahua 5442 that will not allow playback of the SD card.
- Dahua NVR58XX-4KS2 that had custom protocol (ability to add a camera via RTSP) removed possibly to force people to purchase same brand cameras.
- Countless other instances where the camera or NVR simply bricked and became useless.
- Countless examples where the camera or NVR went into Chinese.
- Manufacturers are now preventing their equipment to be updated with an older working firmware after it was updated to a more recent firmware.
