It is now determined by the version + of `python-config` selected during configuration. The + `BUP_PYTHON_CONFIG` environment variable can be set during + configuration to select a particular executable + (e.g. `BUP_PYTHON_CONFIG=python3.9-config ./configure`). See the + `README` for further details. + +* The `bup` executable is now a binary rather than a Python script. + Practically speaking, this means that the Python version is + determined by the `libpython` that the executable is linked against + (selected via `python-config`), and it means that bup will show up + as "bup" in process listings rather than a python invocation. + +* The output of `bup ls` for multiple paths includes each path before + its contents, more closely matching the system `ls`. + +* The `bup ftp` `ls` command should now respect the working directory + (set by `cd`), and that directory has been added to the prompt. + +* Some minor changes have been made to `bup web`'s interface. + +* The `index-cache` is no longer included in the `bup midx` `--dir` + default. + +* Performance may have improved after the relocation of a number of + operations from Python to C, and a number of improvements to the + VFS. + +* The `#bup` IRC channel has moved to https://libera.chat/. + +Bugs +---- + +* Bup should now respect the current umask, directory sgid bit, + etc. when creating new files (e.g. new packfiles). Previously, it + would create them via mkstemp, which would cause them to be readable + only by the current user. + +* Bup should now be able to handle repositories containing signed + commits. + +* `bup tag` has been changed to rely on `git update-ref` instead of + writing the (loose) refs directly so that it can handle packed refs + correctly. + +* `bup save` should be more careful about noting an error and skipping + paths whose type (link, regular file, ...) has changed since + indexing. + +* There should no longer be a narrow window where `save` could store + conflicting symlink targets or conflicting sizes (in the metadata + record and the packfile symlink blob) for a path if the filesystem + changed at just the wrong time during a save. + +* `bup fuse` should no longer become unusable after an unfinished read + of commits associated with tags. The underlying VFS issue may have + affected other commands too. + +* Bup's packfile names should now match git's. Previously bup + computed the SHA1 from just the sorted object list + (cf. `git-index-pack(1)`), but git appears to include the entire + pack file in the hash. + +* Passing idx files to `bup midx` along with `--dir` should now work + correctly. + +* The `bup index --print --long ...` mode fields should now be + formatted correctly with Python 3 (it changed the `oct()` format). + +* Resource usage (e.g. memory) may have improved, given a number of + changes intended to make bup release resources more carefully and + sooner. + +Build and install +----------------- + +* As mentioned above, `PYTHON`'s role during configuration has been + replaced by `BUP_PYTHON_CONFIG`. + +* `./configure` now supports `--with-pylint=[yes|no|maybe]`. + +* Any `CC`, `CPPFLAGS`, `CFLAGS`, or `LDFLAGS` set during + `./configure` should now be preserved across future make + invocations. + +* The build process should now work on systems where `make` isn't GNU + Make (the `Makefile` automatically redirects to `GNUmakefile`). + +* The `PANDOC` path can contain spaces. + +Thanks to (at least) +==================== + +Abdel Said, Arthur Ward, Bas Stottelaar, Brian Minton, Greg Troxel, +Johannes Berg, Mark Hewitt, Muh Muhten, and Rob Browning
