Change Log for SD.Next

Update for 06/14/2023

• simplify token merging
• reorganize some settings

Update for 06/13/2023

Just a day later and one bigger update... Both some new functionality as well as massive merges from upstream

• new cache for models/lora/lyco metadata: metadata.json
  drastically reduces disk access on app startup
• allow saving/resetting of ui default values
  settings -> ui defaults
• ability to run server without loaded model
  default is to auto-load model on startup, can be changed in settings -> stable diffusion
  if disabled, model will be loaded on first request, e.g. when you click generate
  useful when you want to start server to perform other tasks like upscaling which do not rely on model
• updated accelerate and xformers
• huge nubmer of changes ported from A1111 upstream
  this was a massive merge, hopefully this does not cause any regressions
  and still a bit more pending...

Update for 06/12/2023

• updated ui labels and hints to improve clarity and provide some extra info
  this is 1st stage of the process, more to come...
  if you want to join the effort, see https://github.com/vladmandic/automatic/discussions/1246
• new localization and hints engine
  how hints are displayed can be selected in settings -> ui
• reworked installer sequence
  as some extensions are loading packages directly from their preload sequence
  which was preventing some optimizations to take effect
• updated settings tab functionality, thanks @gegell
  with real-time monitor for all new and/or updated settings
• launcher will now warn if application owned files are modified
  you are free to add any user files, but do not modify app files unless you're sure in what you're doing
• add more profiling for scripts/extensions so you can see what takes time
  this applies both to initial load as well as execution
• experimental sd_model_dict setting which allows you to load model dictionary
  from one model and apply weights from another model specified in sd_model_checkpoint
  results? who am i to judge :)

Update for 06/05/2023

Few new features and extra handling for broken extensions
that caused my phone to go crazy with notifications over the weekend...

• added extra networks to xyz grid options
  now you can have more fun with all your embeddings and loras :)
• new vae decode method to help with larger batch sizes, thanks @bigdog
• new setting -> lora -> use lycoris to handle all lora types
  this is still experimental, but the goal is to obsolete old built-in lora module
  as it doesn't understand many new loras and built-in lyco module can handle it all
• somewhat optimize browser page loading
  still slower than i'd want, but gradio is pretty bad at this
• profiling of scripts/extensions callbacks
  you can now see how much or pre/post processing is done, not just how long generate takes
• additional exception handling so bad exception does not crash main app
• additional background removal models
• some work on bfloat16 which nobody really should be using, but why not 🙂

Update for 06/02/2023

Some quality-of-life improvements while working on larger stuff in the background...

• redesign action box to be uniform accross all themes
• add pause option next to stop/skip
• redesigned progress bar
• add new built-in extension: agent-scheduler
  very elegant way to getting full queing capabilies, thank @artventurdev
• enable more image formats
  note: not all are understood by browser so previews and images may appear as blank
  unless you have some browser extensions that can handle them
  but they are saved correctly. and cant beat raw quality of 32-bit tiff or psd :)
• change in behavior: xformers will be uninstalled on startup if they are not active
  if you do have xformers selected as your desired cross-optimization method, then they will be used
  reason is that a lot of libaries try to blindy import xformers even if they are not selected or not functional

Update for 05/30/2023

Another bigger one...And more to come in the next few days...

• new live preview mode: taesd
  i really like this one, so its enabled as default for new installs
• settings search feature
• new sampler: dpm++ 2m sde
• fully common save/zip/delete (new) options in all tabs
  which (again) meant rework of process image tab
• system info tab: live gpu utilization/memory graphs for nvidia gpus
• updated controlnet interface
• minor style changes
• updated lora, swinir, scunet and ldsr code from upstream
• start of merge from a1111 v1.3

Update for 05/26/2023

Some quality-of-life improvements...

• updated README
• created CHANGELOG
  this will be the source for all info about new things moving forward
  and cross-posted to Discussions#99 as well as discord announcements
• optimize model loading on startup
  this should reduce startup time significantly
• set default cross-optimization method for each platform backend
  applicable for new installs only
  • cuda => Scaled-Dot-Product
  • rocm => Sub-quadratic
  • directml => Sub-quadratic
  • ipex => InvokeAI's
  • mps => Doggettx's
  • cpu => Doggettx's
• optimize logging
• optimize profiling
  now includes startup profiling as well as cuda profiling during generate
• minor lightbox improvements
• bugfixes...i don't recall when was a release with at least several of those

other than that - first stage of Diffusers integration is now in master branch
i don't recommend anyone to try it (and dont even think reporting issues for it)
but if anyone wants to contribute, take a look at project page

Update for 05/23/2023

Major internal work with perhaps not that much user-facing to show for it ;)

• update core repos: stability-ai, taming-transformers, k-diffusion, blip, codeformer
  note: to avoid disruptions, this is applicable for new installs only
• tested with torch 2.1, cuda 12.1, cudnn 8.9
  (production remains on torch2.0.1+cuda11.8+cudnn8.8)
• fully extend support of --data-dir
  allows multiple installations to share pretty much everything, not just models
  especially useful if you want to run in a stateless container or cloud instance
• redo api authentication
  now api authentication will use same user/pwd (if specified) for ui and strictly enforce it using httpbasicauth
  new authentication is also fully supported in combination with ssl for both sync and async calls
  if you want to use api programatically, see examples in cli/sdapi.py
• add dark/light theme mode toggle
• redo some clip-skip functionality
• better matching for vae vs model
• update to xyz grid to allow creation of large number of images without creating grid itself
• update gradio (again)
• more prompt parser optimizations
• better error handling when importing image settings which are not compatible with current install
  for example, when upscaler or sampler originally used is not available
• fixes...amazing how many issues were introduced by porting a1111 v1.20 code without adding almost no new functionality
  next one is v1.30 (still in dev) which does bring a lot of new features

Update for 05/17/2023

This is a massive one due to huge number of changes,
but hopefully it will go ok...

• new prompt parsers
  select in UI -> Settings -> Stable Diffusion
  • Full: my new implementation
  • A1111: for backward compatibility
  • Compel: as used in ComfyUI and InvokeAI (a.k.a Temporal Weighting)
  • Fixed: for really old backward compatibility
• monitor extensions install/startup and
  log if they modify any packages/requirements
  this is a deep-experimental python hack, but i think its worth it as extensions modifying requirements
  is one of most common causes of issues
• added --safe command line flag mode which skips loading user extensions
  please try to use it before opening new issue
• reintroduce --api-only mode to start server without ui
• port all upstream changes from A1111
  up to today - commit hash 89f9faa

Update for 05/15/2023

• major work on prompt parsing this can cause some differences in results compared to what you're used to, but its all about fixes & improvements
  • prompt parser was adding commas and spaces as separate words and tokens and/or prefixes
  • negative prompt weight using [word:weight] was ignored, it was always 0.909
  • bracket matching was anything but correct. complex nested attention brackets are now working.
  • btw, if you run with --debug flag, you'll now actually see parsed prompt & schedule
• updated all scripts in /cli
• add option in settings to force different latent sampler instead of using primary only
• add interrupt/skip capabilities to process images

Update for 05/13/2023

This is mostly about optimizations...

• improved torch-directml support
  especially interesting for amd users on windows where torch+rocm is not yet available
  dont forget to run using --use-directml or default is cpu
• improved compatibility with nvidia rtx 1xxx/2xxx series gpus
• fully working torch.compile with torch 2.0.1
  using inductor compile takes a while on first run, but does result in 5-10% performance increase
• improved memory handling
  for highest performance, you can also disable aggressive gc in settings
• improved performance
  especially after generate as image handling has been moved to separate thread
• allow per-extension updates in extension manager
• option to reset configuration in settings

Update for 05/11/2023

• brand new extension manager
  this is pretty much a complete rewrite, so new issues are possible
• support for torch 2.0.1
  note that if you are experiencing frequent hangs, this may be a worth a try
• updated gradio to 3.29.0
• added --reinstall flag to force reinstall of all packages
• auto-recover & re-attempt when --upgrade is requested but fails
• check for duplicate extensions

Update for 05/08/2023

Back online with few updates:

• bugfixes. yup, quite a lot of those
• auto-detect some cpu/gpu capabilities on startup
  this should reduce need to tweak and tune settings like no-half, no-half-vae, fp16 vs fp32, etc
• configurable order of top level tabs
• configurable order of scripts in txt2img and img2img
  for both, see sections in ui-> settings -> user interface

Update for 05/04/2023

Again, few days later...

• reviewed/ported all commits from A1111 upstream
  some a few are not applicable as i already have alternative implementations
  and very few i choose not to implement (save/restore last-known-good-config is a bad hack)
  otherwise, we're fully up to date (its doesn't show on fork status as code merges were mostly manual due to conflicts)
  but...due to sheer size of the updates, this may introduce some temporary issues
• redesigned server restart function
  now available and working in ui
  actually, since server restart is now a true restart and not ui restart, it can be used much more flexibly
• faster model load
  plus support for slower devices via stream-load function (in ui settings)
• better logging
  this includes new --debug flag for more verbose logging when troubleshooting

Update for 05/01/2023

Been a bit quieter for last few days as changes were quite significant, but finally here we are...

• Updated core libraries: Gradio, Diffusers, Transformers
• Added support for Intel ARC GPUs via Intel OneAPI IPEX (auto-detected)
• Added support for TorchML (set by default when running on non-compatible GPU or on CPU)
• Enhanced support for AMD GPUs with ROCm
• Enhanced support for Apple M1/M2
• Redesigned command params: run webui --help for details
• Redesigned API and script processing
• Experimental support for multiple Torch compile options
• Improved sampler support
• Google Colab: https://colab.research.google.com/drive/126cDNwHfifCyUpCCQF9IHpEdiXRfHrLN
  Maintained by https://github.com/Linaqruf/sd-notebook-collection
• Fixes, fixes, fixes...

To take advantage of new out-of-the-box tunings, its recommended to delete your config.json so new defaults are applied. Its not necessary, but otherwise you may need to play with UI Settings to get the best of Intel ARC, TorchML, ROCm or Apple M1/M2.

Update for 04/27/2023

  works for text and image generation, but not for process as there is no progress bar reported there to start with
• force unload xformers when not used
  improves compatibility with AMD/M1 platforms
• add styles.csv to UI settings to allow customizing path
• add --skip-git to cmd flags for power users that want
  to skip all git checks and operations and perform manual updates
