Full Changelog: v0.7.0...v0.8.0

v0.7.0 — mlisp-bugs

Added

• mlisp-bugs: Debbugs-compatible email bug tracker (#69 #70)
  • Maildir-as-database architecture: bug state derived by scanning the archive, exactly as Debbugs does
  • Wire protocol: <pkg>-bugs-submit@host, <pkg>-bugs-N@host, <pkg>-bugs-N-done@host, <pkg>-bugs-control@host
  • Control commands: severity, tags, close, reopen, retitle, owner, forwarded, block, merge, quit
  • New binary mlisp-bugs + ASDF system mlisp-bugs.asd
  • New admin subcommands: bugs-add-package, bugs-list-packages, bugs-list, bugs-show, bugs-report, install-bugs-procmail
• 29 new BATS specs (test_mlisp_bugs.bats)

Fixed

• maildir-unique-name: reads PID from /proc/self/status (avoids sb-posix dependency); eliminates Maildir filename collisions on rapid sequential writes
• maildir-messages wildcard: (make-pathname :name :wild :type :wild) fixes directory listing for files with hostname extensions

Test coverage: 445 tests (78 FiveAM + 367 BATS)

Full Changelog: v0.6.2...v0.7.0

v0.6.2

Added

• Self-hosted CI (.github/workflows/): build-and-test workflow on a self-hosted runner
• Send-email workflow: GitHub Actions workflow for outbound mail testing
• Migration guide: documentation for upgrading from prior versions

Full Changelog: v0.6.1...v0.6.2

v0.6.1

Added

• Quicklisp dist (dist/): self-hosted distribution at http://panix.com/~denzuko/dist/mlisp/distinfo.txt. make dist generates from HEAD; make dist-upload rsyncs to panix.com. Resolves the Debian packaging Quicklisp dependency — build scripts already conditionally load Quicklisp when present and fall through to bare ASDF.
• contrib/mlisp.el: Emacs minor mode for mlisp administration. Shell-out backend (default): calls mlisp-admin binary directly. SLIME/vlime backend (mlisp-use-slime t): evaluates in connected SBCL image. 16 M-x mlisp-* commands; completing-read on live list IDs; set-option completion over all known keys. (mlisp-setup-keys "C-c m") binds all commands under a prefix key.
• Makefile: dist, dist-upload, dist-clean targets.

Full Changelog: v0.6.0...v0.6.1

v0.6.0

Added

• Subscriber self-service commands (src/requests.lisp): info, who (gated by :advertised), query (own settings), set mail|nomail|digest
• BITNET-style archive search (src/requests.lisp): search <keyword>, index, get <list> <N> against Maildir archives; :search-enabled per list
• AllFix file distribution (src/state.lisp): files command (FILES.BBS), mlisp-admin hatch (add file + announce); :distrib-files state tracking
• Plugin filter pipeline (src/filters.lisp): :pre-filter and :post-filter hooks; exit codes 0=pass 1=reject 2=hold 3=discard; space-separated filter chains; invoke-filter-chain / invoke-single-filter
• Example filters: etc/filters/spamassassin, etc/filters/clamav, etc/filters/gemini-archive, etc/unsubscribe-cgi/unsub.sh
• mlisp-admin hatch: add file to distrib archive + announce to subscribers
• 27 new BATS specs (test_mlisp_v06.bats + test_mlisp_filters.bats)

Fixed

• string-trim " \t" trimming literal t from filter paths — fixed to (list #\Space #\Tab) (classic CL footgun: \t in a string is \ + t)
• string-to-message: CRLF normalisation — strip \r before header parsing
• sb-posix:getpid replaced with (random 99999) for standalone binary compat
• Duplicate windowed-increment-bounce removed from diagnose.lisp
• Forward declarations added to distrib.lisp, metrics.lisp
• *compile-file-failure-behaviour* set to :warn in all build scripts

Test coverage: 416 tests (78 FiveAM + 338 BATS)

Full Changelog: v0.5.0...v0.6.0

• DKIM-Signature stripped on redistribution (RFC 6376 §5)
• Authentication-Results preserved as X-Original-Authentication-Results
• RFC 8058 one-click unsubscribe: List-Unsubscribe-Post when :unsubscribe-url configured; HTTPS URI first in List-Unsubscribe
• List-Id domain derived from :drop-address (not hardcoded)
• List-Archive and List-Owner headers when configured
• Complete manpages: mlisp(1), mlisp-admin(1), mlisp-intro(7), mlisp-distrib(1); make man target
