- Introduced a new `conflicts` field in the `Alternatives` struct to track conflicting packages.
- Updated database schema to include a `conflicts` table and related queries.
- Enhanced package specification handling to include conflicts in TOML serialization and deserialization.
- Modified the interactive package creation to allow input for conflicting packages.
- Updated source repository index creation to handle conflicts and added relevant statistics.
- Adjusted tests to cover new conflicts functionality in package alternatives.
- execute transaction pre hooks at transaction start and post hooks at transaction end
- add batched hook execution with ordered "(n/total)" logging
- refactor install flows to plan package actions first, then run hooks around commits
- add `build.flags.ltoflags` and `build.flags.use_lto` (default: true)
- export `LTOFLAGS` and append LTO flags to `CFLAGS`, `CXXFLAGS`, and `LDFLAGS`
unless `use_lto = false`
- make autotools CFLAGS expansion use the final computed CFLAGS value
- update spec parsing/appends, interactive TOML output, docs, and contrib build config
- bump project version to 0.8.0 and update `zip` to 8.2.0
- add `depot repo index [DIR] [--subdir ...]` to generate `depot-index.tsv`
- use deterministic, git-friendly TSV format with package/provides rows
- teach source lookup to prefer repo index files and fall back to TOML scanning
- add index generation/loading/fallback tests
- document new command in README
- add source.cherry_pick (and cherry-pick alias) to package spec parsing/serialization
- apply listed cherry-picks in order after git checkout
- reject cherry_pick on non-git sources with explicit error
- include cherry_pick in interactive spec TOML output
- add parsing/behavior tests and update Source test fixtures
- split CLI definitions and command execution out of main.rs into new cli.rs and commands.rs modules\n- add transaction hook support via /etc/depot.d/hooks/*.toml with pre/post phases, operation/package/path filters, wildcard negation, and optional affected-path stdin\n- execute transaction hooks around install/update/remove operations and add package-action prompts for install/build/remove flows\n- require and verify detached minisign signatures for binary package archives when allow_unsigned=false, including cache handling and tests\n- persist optional dependencies from package metadata into repo index data and include optional deps in produced metadata\n- update dependency/planner logic to ignore dependencies provided by local split outputs and stop pulling test deps into install planning\n- auto-disable tests when required test dependencies are missing instead of hard-failing build/install paths\n- improve autotools defaults by injecting standard install directory flags when supported and preserving user overrides\n- remove static .a archives during staging by default with new build.flags.no_delete_static escape hatch\n- preserve symlinks and file metadata (permissions/timestamps) in extractor fallback copy path and add regression tests\n- refresh README docs for detached package signatures, optional dependencies, and transaction hooks\n- adjust dependency set: add filetime, disable reqwest default features, and simplify git2/OpenSSL linkage
