GIMP 2.10.8

What's new in this version:

Core:
- Use adaptive chunk size in GimpProjection when rendering the projection asynchronously, rather than using a fixed chunk size. This provides a better trade-off between throughput and responsiveness dynamically, based on how fast the processing is

Tools:
- In all selection tools, show error on attempt to subtract-from/intersect-with empty selection
- Fix text along path not working with vertical text
- Fix Text tool's frame position when undoing a move operation
- Streamline Text tool's drawing blocking/unblocking logic
- When moving a text layer using the text tool (through alt+drag), don't change the layer's box mode to "fixed", which is unnecessary, since the layer's size isn't affected
- Transform and deformation operations now maintain color for fully transparent pixels, making unerase and curves manipulation of alpha channel more reliable
- All transform tools now apply changes when you save or export/overwrite an image without pressing Enter first to confirm changes
- Heal, Dodge/Burn, Smudge, and Convolve tools now adjust the processed buffer and mask_buffer regions according to the changes made to the application region, as calculated by intersecting it with the drawable and mask extents. This fixes wrong application position when painting on a drawable whose origin is above/to the left of the image's origin, and there's a selection active

Plug-ins:
- Port all plug-ins to the new iterator API in GEGL
- Improve automatic detection of HEIC/HEIF files
- Improve RawTherapee discovery by looking up registry key (should become useful with RawTherapee 5.5 and more)

Usability:
- Compatibility information in the Save dialog is now more understandable. The minimum GIMP version for the XCF file is always written down when it is GIMP 2.8 or over. The list of features warranting the minimum version is now listed in an expander container rather than as tooltip, which makes it more discoverable. The warning on compression is now displayed as its own text under the checkbox and not as additional text to the minimum GIMP version label

CLI:
- New self-explanatory --enable-win32-debug-console CLI option

Debugging:
- New GimpBacktrace API provides an interface for creating and traversing multi-threaded backtraces, as well as querying symbol information. Backends are available for Linux and Windows.
- Performance log recording now available in the Dashboard dock. The log contains a series of samples of the dashboard variables, as well as the full program backtrace, when available. As such, it essentially acts as a built-in profiler, which allows us to correlate program execution with the information available through the Dashboard
- New performance-log-expand.py tool decodes a delta-encoded performance log by expanding the deltas, producing a log where each sample (and other relevant elements) contain complete information. The structure of expanded logs is identical to that of delta-encoded logs, the expanded log simply has no deltas
- New performance-log-resolve.py tool resolves symbol information in backtraces. The logs produced by GIMP only specify the program counter at each stack frame, providing an address-map to map program-counter addresses to actual symbols separately. This tool looks up each program-counter address in the address map, incorporating the relevant symbol information directly into the backtrace
- New performance-log-deduce.py tool that statistically deduces the correct thread states based on backtrace address frequency, fixing local inaccuracies
- New performance-log-viewer.py tool that is a viewer for GIMP performance logs, with a sample-selection area at the top and an information area at the bottom. The sample-selection area visualizes the sampled variables and markers using a simultaneous set of plots, and displays the currently selected samples. The information area shows global information stored in the log, as well as information specific to the currently selected samples, including variable listing and statistics, full backtrace, and profile/call-graph information
