38

<dl>

39

<dt>06/2001, 0.1</dt> <dd>First alpha release.</dd>

40

41

<dt>06/2001, 0.2</dt> <dd>Minor changes.</dd>

42

43

<dt>06/2001, 0.3</dt> <dd>Major changes to how keys are identified and

44

looked up.</dd>

45

46

<dt>06/2001, 0.4</dt> <dd>Adding more customization features.</dd>

47

48

<dt>11/2001, 0.4.4</dt> <dd>Cleaned up some error messages; added -nps

49

mode.</dd>

50

51

<dt>11/2001, 0.4.5</dt> <dd>Added ‘gpg-options’ config item with

52

default ‘--no-options’. (Forgot to add this note as well....)</dd>

53

54

<dt>11/2001, 0.5.0</dt> <dd>Dumped -verify and -decrypt modes in

55

favour of the multiple-block ‘-display’ mode. Added -help. Added

56

caching. Added more switches relating to caching. Better output

57

formatting.</dd>

58

59

<dt>11/2001, 0.5.1</dt> <dd>Improved menus. Tidied up some of the

60

interface. Added -s, which does the same as -nps.</dd>

61

62

<dt>12/2001, 0.5.2</dt> <dd>Tidied disclaimer. Added synonyms for

63

-help (-h, -?, --help, --h) Cleaned up menus; keypresses aren't echoed

64

any longer.</dd>

65

66

<dt>12/2001, 0.5.3</dt> <dd>Altered packaging to include version in

67

directory name. Changed names of some -clear options to be a bit more

68

sensible. Changing config settings method (big change). Making -s

69

the default operation. Some rearrangement of code, constants. Some

70

configuration editing possible via Topal. Send has access to

71

configuration menu. </dd>

72

73

<dt>12/2001, 0.5.4</dt> <dd>Bug fix; one-off error in the sending

74

menus.</dd>

75

76

<dt>12/2001, 0.5.5</dt> <dd>Removed redundant examples directory.

77

Changed over to HTML documentation. Tweaked the RELEASE stuff. Use

78

space instead of enter when waiting to continue: this looks forward to

79

offering a help option at every prompt. The receive/blocks

80

stuff now uses an expanding array. The GPG return value is checked

81

when receiving: if it's bad, then some bits of the output are omitted;

82

the cache file is not written. The date bit of Topal output moved

83

onto the previous line (echo -n blah blah).</dd>

84

85

<dt>12/2001, 0.5.6</dt> <dd>Adding installation instructions. Using

86

tee and PIPESTATUS to get stderr on screen during receiving while also

87

saving that output and recording gpg's exit status. Changed RELEASE

88

filename to release. Tidied up the Makefile. Invalid passphrase

89

messages are grep'd out of the output. Added ‘fast continue’ options.

90

Key lists in the configuration section now use expanding arrays.

91

Changed key details selection message. Secret key selection now

92

offers a menu of secret keys on the secret keyring. Initial recipient

93

search excludes keys in XK list. Added key search/selection menu

94

choice - much nicer to use than the add menu. More configuration

95

stuff added (still more to do, although the config file can always be

96

used). Partial documentation update.</dd>

97

98

<dt>2/2002, 0.5.7</dt> <dd>Adding limited RFC2015/MIME decoding of

99

multipart email.</dd>

100

101

<dt>2/2002, 0.5.8</dt> <dd>Adding mime-construct to configuration in

102

expectation of more RFC2015 features. Put test for the config file

103

existing before actually attempting to read it (oops). Added -O2

104

-Wall and the TOPALDEBUG variable for compiling. Put up WWW page via

105

own Freeserve site. Announcing via Freshmeat. Automating output WWW

106

site generation (all the grunge in the Makefile).</dd>

107

108

<dt>3/2002, 0.6.0</dt> <dd>Distribution uses a gzip'd binary now....

109

Added a pre-built binary that is statically linked against the GNAT

110

stuff so that people don't need to acquire GNAT first (this, I

111

believe, complies with the GNAT licence). Added the scripts

112

topal-fix-email and topal-fix-folder. This makes it a lot easier to

113

work with other people's multipart/signed or /encrypted email.

114

Procmail recipe added to this README. Added display of

115

application/pgp messages. Including the text of one of these in a

116

reply might be difficult, but then, it was difficult without topal's

117

mangling. At least they can be verified and read now. -sendmime

118

option added. Hack needed (in topal-pine-patch [now pine-4.44.patch])

119

to allow non-text/blah content-types in Pine. RFC2015 send and

120

received done (including micalg detection when sending clearsigned

121

messages: list used from RFC3156.). Ditto for application/pgp, but

122

I'm not sure of some of the parameters, since I've only ever seen

123

signed emails of this form. Removed some of the waits for execution,

124

since it seems reliable. Added error checking on return value of GPG

125

in sends.</dd>

126

127

<dt>3/2002, 0.6.1</dt> <dd>The Content-Type for MIME sending is

128

displayed on the screen using ‘cat’ rather than ‘less’, which was

129

getting to be annoying. Two changes that are related to how I

130

manage the source code: Slight tweak to makefile for keeping track

131

of RCS files; and using rcs -n<symbolic-name> to tag the

132

released files.</dd>

133

134

<dt>3/2002, 0.6.2</dt> <dd>MIME clear-signed messages: trailing blank

135

lines are now deleted before signing (this would cause BAD signature

136

when verifying on some other MTAs). Added remarks to documentation

137

about the patch to Pine and attachments.</dd>

138

139

<dt>4/2002, 0.6.3</dt> <dd>RFC1847 multipart encapsulation added.

140

(See section 6.1 of RFC3156.) Cleaned up related receiving/caching

141

behaviour. Another MIME clear-signed messages bugfix. This one

142

sorts out line-end conventions correctly. New patch for Pine: this

143

stops a SEGFAULT when using RFC2015 stuff and other attachments at the

144

same time. Updated documentation; added man pages for the two scripts.</dd>

145

146

<dt>4/2002, 0.6.4</dt> <dd>New patch for Pine. Adds a workaround for

147

the problem where some versions of MS Exchange would silently lose

148

inbound MIME clearsigned email. It turns out that a slight formatting

149

change stops the problem.</dd>

150

151

<dt>5/2002, 6/2002; 0.6.5, 0.6.6, 0.6.7, 0.6.8</dt> <dd>Adding more debugging,

152

mostly to the menus code. Used for tracking down a nasty problem

153

causing exceptions. Many thanks to Felix Madlener for pointing this

154

out and testing the revised code.</dd>

155

156

<dt>7/2002, 0.6.9</dt><dd>Renamed the Pine patch for when new versions

157

come out. (It's still the same patch as for Topal 0.6.4.) Added trap

158

for non-existent file when using ‘-s’. Cache directory as well as

159

.topal directory is also chmod'd to 700. Added README.txt to package

160

file (even though it's generated from the .html) so that those who

161

just want to ‘less’ it (instead of firing up a HTML reader) can do so.</dd>

162

163

<dt>8/2002, 0.7.0</dt><dd>Changed email address in man page. Lots more

164

exception handling for extra info when something goes wrong. Moderate

165

code reorganisation: mostly splitting blocks of code out for future

166

work. Fixed ‘bug’ (feature?) where send fails if a public key is

167

unusable (although this may risk sending plaintext through; we assume

168

that if an output file was generated, then the GPG errors weren't

169

fatal). Now we check instead if the output file exists. Checking all

170

source files for any similar bugs in menus (cf. the 5/2002 entry).

171

Modified MIME RFC2015 receiving function so that it isn't so reliant

172

on shell calls of sed (which can fall over with nasty characters in an

173

incoming emails boundary). Moreover, it can now cope with MIME parts

174

that don't end with a newline. Tweaking MIME/verify cache handling:

175

we shouldn't actually get an output file from GPG (since we're only

176

verifying one part with the other); we put a vague warning if this

177

happens, and trap when reading the cache. Added content-type to

178

plaintext for MIME/encrypted. Documentation update.</dd>

179

180

<dt>8/2002, 0.7.1</dt><dd>Fixed minor bug with inverted return code

181

(‘-s’ trap). Doc update.</dd>

182

183

<dt>9/2002, 0.7.2</dt><dd>Fixed minor bug in key list handling code

184

(dealing with key selection).</dd>

185

186

<dt>9/2002; 0.7.3, 0.7.4 (BETA)</dt><dd>Disposed of the dependency on a shell by

187

introducing Ada bindings for fork/exec/dup/pipe/glob, etc.. Several

188

external binaries are no longer needed (cat, echo). Most return codes

189

are now properly checked (although still need to do a better audit).

190

Followed Eduardo Chappa's advice and changed Pine patch version

191

letter. Miscellaneous cleanups and fixes. Many thanks to Peter

192

Losher for giving me the incentive to sort out the external calls.</dd>

193

194

<dt>9/2002; 0.7.5 (BETA)</dt><dd>Tidying up structure of external calls, and

195

how the various messages are built up and torn down. Changed the lynx

196

switches at the suggestion of Felix Madlener (many thanks!). When

197

receiving MIME encrypted attachments, the output is not included in

198

the Topal output, but only in the metamail invocation.</dd>

199

200

<dt>10/2002; 0.7.6 (BETA)</dt><dd>Explicitly noted which versions are

201

not intended for general use (beta versions). Rearranged command line

202

parsing for more flexibility in future.</dd>

203

204

<dt>10/2002; 0.7.7 (BETA)</dt><dd>Re-implementing topal-fix-email and

205

topal-fix-folder as part of the main topal binary. This removes the

206

(script) dependency on munpack, but adds formail and diff to the main

207

binary. Fixed some missing bits for particular binaries in

208

configuration handling. Adding ‘important changes from last stable

209

version’ documentation. Tweaked the body extraction procedure.

210

Tweaked some output messages. Major changes to menus: they now use

211

enumerated types rather than integers.... Tweaking cl_menu some

212

more. Added ‘pass-thu’ option to send menu (so you can always use the

213

Topal filter. This might also fix the minor problem with text/html

214

occasionally being sent when it shouldn't be....) Fixed bug where

215

MIME decrypt failure would still cause metamail to be invoked, but

216

that's a waste of time.</dd>

217

218

<dt>10/2002; 0.7.8</dt><dd>Clearing out case statements with ‘when

219

others’. Tidying up sending.adb. Fixed problem in MIME output where

220

a leading blank line was added. Finally implemented ‘topal

221

--fix-folders’ functionality added. No longer need the two old

222

scripts (I hope)! Another documentation tidy-up. Added

223

‘inline-separate-output’ option: this effectively turns off the GnuPG/Topal

224

wrappers in output. However, the side-effect is that the cache must

225

be cleared when upgrading to this version.

226

</dd>

227

228

<dt>11/2002; 0.7.9</dt><dd>Added some infrastructure for

229

encrypting/signing attachments (but this is nowhere near working yet).

230

Documentation and manpage update (again). Seems stable, will release.

231

</dd>

232

233

<dt>2/2003; 0.7.10, 0.7.11</dt><dd>Tweaking distribution pages (mkdistrib).

234

Including patches against Pine versions 4.50 and 4.53. (They're all

235

more-or-less the same patch. It's pretty

236

easy to apply them against 4.51 and 4.52 if you feel so inclined.)

237

Further doc clean up (particular the stuff about important changes

238

from previous stable versions). Implemented Felix M.'s suggestion for

239

handling non-existant command-line options: things that aren't valid

240

options, but are prefixed with a ‘-’ get a more helpful error

241

message. --fix-email workaround also writes out the original input in

242

the exception handler. Changed recommended procmail recipe so that

243

Topal's exit code is checked.

244

</dd>

245

246

<dt>2/2003; 0.7.12</dt><dd>Adding ‘workaround-error-log’ file to

247

.topal. This accepts output from topal --fix-email when it fails to

248

exit cleanly. Not quite clear if this bit works yet (was tracking

249

down other problem). It appears that when running without a real

250

terminal, the call to set_echo fails. Odd. Nasty workaround

251

implemented.

252

</dd>

253

254

<dt>2/2002; 0.7.13</dt><dd>Added missing includes to ada-echo-c.c.

255

Perhaps related to issue in the previous entry.</dd>

256

257

<dt>4/2003; 0.7.13b</dt><dd>Bug fix release only - backported from

258

(not-yet-released 0.8.0). Fixed bug when

259

changing own signing key using the -config option - thanks to Stewart

260

James for the bug report. </dd>

261

262

<dt>10/2003; 0.7.13.2</dt><dd>Bug fix release only - backported from

263

(not-yet-released 0.8.0). Changed bug fix versioning scheme.

264

Makefile now links properly against static GNAT runtime. Fixed

265

problem which manifests as: ‘relocation error: /lib/libreadline.so.4:

266

undefined symbol: BC’ (needed instruction to link against ncurses) -

267

thanks to Marty Hoff for the bug report. Added patch against Pine

268

version 4.58.</dd>

269

270

<dt>10/2003; 0.7.13.3</dt><dd>Now use -gnatwa and -gnato for all Ada

271

compilation. It was omitted from the main binary build command

272

before. Fixed all the resulting warnings.</dd>

273

274

<dt>1/2004; 0.7.13.4</dt><dd>Patched externals calls for errno to

275

prevent (in some cases) warnings from ld.so, and in other cases,

276

failures to build.</dd>

277

278

<dt>6/2004; 0.7.13.5</dt><dd>Added patch against Pine version

279

4.60. Updated some notices.</dd>

280

281

<dt>1/4/2005; 0.7.13.6</dt><dd>Calls to the GPG binary now have LANG

282

set to C before exec so that we don't have to worry about different

283

language output in GPG. Thanks for Joern Brederec for the bug report

284

and suggestion of how to fix it.</dd>

285

286

<dt>2005-2007</dt><dd>Four internal development releases junked.</dd>

287

288

<dt>8/1/2008; release 55</dt><dd>

289

<tt>--fix-email</tt> now replaces the original message with a

290

multipart/misc wrapper, rather than expanding it into a

291

multipart/alternative message.

292

293

Replaced some key selection code. Hopefully, this reduces the number

294

of locale-dependent and GPG version-specific problems. Additionally,

295

revoked, disabled and invalid keys are no longer offered; checks are

296

made to ensure that the key is valid for encryption/signing when applicable.

297

298

New patch for Alpine 1.00. Includes configuration setting.

299

300

The ‘pass through unchanged’ send option no longer modifies the

301

content-type to text/plain.

302

303

Should now build and run on Cygwin.

304

305

Licence is now GPL-3.

306

307

Attempt to prevent potential memory leak (if running for a long time)

308

by making the implementation of <tt>expanding_array</tt> a controlled type.

309

310

Cleaned up Ada source to reduce warnings.

311

312

Other minor changes, e.g., better checks on keylists, documentation clean-up.

313

314

Changed <a href="#release-numbering">release numbering</a>.

315

316

HTML cleaned up and CSS added.</dd>

317

318

<dt>8/1/2008; release 56</dt><dd>

319

<tt>--read-from</tt> option added to select different signing keys

320

depending on the From line. Also added <tt>sake</tt> and <tt>sxk</tt>

321

configurations.

322

323

Fixed bug in Keys.Remove.Key (didn't match if the full fingerprint

324

wasn't given).

325

326

Command-line parser now accepts 1 or more hyphens for any option.

327

328

Improved keylist documentation.

329

330

Corrected release date for release 55... oops.

331

</dd>

332

333

<dt>8/1/2008; release 57</dt><dd>

334

Initial attempt at supporting attachments within Topal.

335

336

Changed MIME boundary detection code (the previous algorithm couldn't

337

cope with multipart included in a signed email). Please tell me if

338

this breaks your emails....

339

340

Bug fix to _INCLUDEALLHDRS_ - it needs to turn the CRLF back into LF

341

or it might chop off some of your message....

342

</dd>

343

<dt>22/6/2008; release 58</dt><dd>

344

UI improvements (count keys in keylist, clearer indication of position

345

in menus).

346

347

Added patch for Alpine 1.10. Renamed all patch files.

348

349

Default paths for binaries are no longer absolute.

350

351

Configuration files now allow comments, but they're not preserved by Topal.

352

353

Added more exception handling messages.

354

355

Sending and receiving both save off original input as tempfiles to

356

help debugging.

357

358

Added --ask-charset command line option. This is really only for

359

testing a new workaround for locale-related bad signatures. Please

360

see <a href="#locale-problems">locale problems</a> in the notes and

361

send feedback.

362

363

Started removing dependency on mime-construct; new source files mime.ad[sb].

364

365

Build date added to binary.

366

</dd>

367

<dt>3/7/2008; release 59</dt><dd>

368

Added sequence numbers to temporary files to reduce possible name

369

conflicts.

370

371

The makefile's install target now installs to INSTALLPATH. This can

372

be overridden, e.g., <tt>make install INSTALLPATH=/usr/local</tt>.

373

The four more specific paths, INSTALLPATHBIN, INSTALLPATHMAN,

374

INSTALLPATHDOC and INSTALLPATHPATCHES can also be overridden. Fixes

375

request from Nils Schlupp re: ebuild.

376

377

The --ask-charset command-line option is now only used if a bad signature

378

is returned; a second attempt is then made if a different character

379

set is suggested by the user.

380

</dd>

381

<dt>13/7/2008; release 60</a></dt><dd>

382

Update installation instructions for make install.

383

384

We now use a modified version of Jeffrey S. Dutky's mime-tool instead

385

of mime-construct for creating MIME messages. We include our modified

386

version in the Topal tarball (since both are GPL, and our

387

modifications are needed if creating MIME messages).

388

389

MIME viewing can now use metamail, use run-mailcap or save the attachment to the

390

folder <tt>~/.topal/viewmime</tt> (which you can then open in

391

Alpine). run-mailcap and saving support are new.

392

393

Sending menu allows user to view and edit the email. A quicker

394

method for changing/setting the signing (own) key is available.

395

</dd>

396

<dt>14/7/2008; release 61</dt><dd>

397

An initial, rather crude, but (for my purposes at least) effective

398

remote mode for sending.

399

400

Some history is now saved.

401

</dd>

402

<dt>17/7/2008; release 62</dt><dd>

403

Added basic support for S/MIME verification of messages.

404

405

Quoted-printable encoder (in MIME-tool) improved (single dots and

406

leading "From ") as per RFC2049.

407

408

Decode quoted-printable and base64 before calling run-mailcap.

409

410

Ignore errors in strip in Makefile (trips up Cygwin, which expects the

411

executable to be foo.exe).

412

413

Update feature list for remote sending.

414

415

Internal changes to configuration storage.

416

</dd>

417

<dt>31/8/2008; release 63</dt><dd>

418

Update change list for release 62 (omitted some items...).

419

420

Give a sensible warning message instead of dying with an exception

421

when (1) signing operations are called without own key set; (2)

422

attempting to choose own key without any secret keys available.

423

424

Added some hints in the documentation.

425

426

Initial attempt at supporting remote decryption.

427

428

Handle SIGINT ourselves so that temporary files are cleaned up. Also

429

clean up more often when exceptions occur.

430

</dd>

431

<dt>24/10/2008; release 64</dt><dd>

432

Update feature list for release 63's remote decryption support.

433

434

Add patch to Topal sources for Cygwin. (The recent interrupt code

435

doesn't build.)

436

437

Bug fix: temporary files weren't being deleted, because

438

Rm_Tempfiles_PID hadn't been changed to match Temp_File_Name.

439

440

Added patch for Alpine 2.00. Alpine's S/MIME needs to be turned off

441

for Topal's S/MIME verification to work.

442

443

Bug fix in Externals.Simple.Guess_Content_Type.

444

</dd>

445

<dt>1/5/2009; release 65</dt><dd>

446

MIME sending now uses the current locale as the content-type header charset.

447

448

MIME receiving (verification) tries to use the character set given in

449

its first attempt.

450

451

Signing calls to GPG use <tt>--textmode flag</tt> (shouldn't be needed

452

if the dos2unix calls work, but experiments suggest some problems if

453

we don't do this).

454

455

Fix remote server so that emails with multiple recipients are handled

456

properly.

457

458

Added new patch to Alpine that might make it easier to read

459

multipart signed/encrypted messages. This makes the procmail recipe

460

redundant, but needs more testing.

461

462

Attempt to manage different character sets when verifying S/MIME.

463

464

MIME messages now include a prolog explaining that they're OpenPGP

465

messages. Also added appropriate Content-Disposition headers to help

466

client programs.

467

468

Update docs re: Alpine patches.

469

470

Code cleanup (e.g., vars that could be declared constant, and some

471

unused procedure formals).

472

</dd>

473

<dt>6/6/2009; release 66</dt><dd>

474

Removed spurious spaces from Topal ‘-----’ text that were messing up

475

format=flowed text. Note that this doesn't fix cache files that

476

already have this problem.

477

478

Changed the default sending and receiving GPG options (use

479

the <tt>-default</tt> option to see them). This does not override

480

whatever is in your current <tt>.topal/config</tt> file.

481

482

Added a configuration option ‘omit-inline-disposition-name’:

483

apparently some mail services mistreat inline MIME parts if they have

484

a filename. If this option is set, then no filename parameter is

485

added to inline content-disposition headers. The option can be

486

changed via the configuration menu.

487

</dd>

488

<dt>6/6/2009; release 67</dt><dd>

489

Added another configuration option ‘omit-inline-disposition-header’.

490

If a disposition header of value inline would be added, it's simply

491

omitted altogether.

492

</dd>

493

<dt>27/6/2009; release 68</dt><dd>

494

Minor bug fix with configuration handling of

495

omit-inline-disposition-header.

496

497

Added new configuration option save-on-send.

498

499

A range of major and minor changes to the sending interface.

500

501

Added the sd configuration option that allows keys or emails to be

502

associated with particularly sending options.

503

504

When secret keys aren't available, still try to add a suitable key for

505

self for encryption.

506

507

MIME viewer setting has been replaced by two: one for decrypt and one

508

for verify.

509

510

Bad lines in the configuration file now result in a warning, not an exception.

511

512

Internal modifications to configuration handling.

513

</dd>

514

<dt>21/7/2009; release 69</dt><dd>

515

No longer calling an external app for line-end conversions.

516

517

Added a note re: Alpine's S/MIME message about certificates.

518

519

Show the list of recipients just before sending (from the to/cc/bcc

520

lists; not lcc, as Alpine doesn't pass those to in the _RECIPIENTS_

521

token). The idea is to allow the user to spot the “oh no, I didn't

522

intend to email that person” problem.

523

</dd>

524

<dt>22/9/2009; release 70</a></dt><dd>

525

Added <tt>use-agent</tt> configuration option. This has three values:

526

(1) never use an agent, (2) only use it for decryption, (3) always use

527

it. Don't put GPG's <tt>--[no-]use-agent</tt> options in any other

528

configuration options or it might be confusing.

529

530

Adding attachments when using a non-MIME mode forces a change to a

531

suitable mode (where possible).

532

533

Presentation changes for recipient list check.

534

535

Fixed a minor typo in a user message.

536

</dd>

537

<dt>25/2/2010; release 71</a></dt><dd>

538

Added more MICALGs from RFC4880.

539

540

Handle missing Content-Type headers in multipart messages.

541

542

Reorganise menus: hopefully, they're easier to read now.

543

Add some colourisation (this can be disabled by

544

setting <tt>ansi-terminal</tt> to <tt>off</tt>).

545

Assorted tidying.

546

547

Warn if sending defaults to encryption, but some keys are missing.

548

549

Add -pd - pipe-display mode. Takes stdin and treats it as a MIME

550

email for display/verification.

551

552

Release code is now taken from the <tt>README.html</tt> file rather

553

than a separate <tt>release</tt> file.

554

555

Slight clean-up of this README.

556

</dd>

557

<dt>25/2/2010; release 72</a></dt><dd>

558

Fix menus for non-Pine sending. (‘Go’ wasn't working!)

559

560

Trap attempts to encrypt when no keys are in the key list.

561

562

Minor change to distrib text and Makefile.

563

564

Distrib target in Makefile now uses GPG agent.

565

</dd>

566

567

568

569

570

<dt><a name="last-changes"/>29/4/2011; release 73</a></dt><dd>

571

Fix crash when sending attachments with spaces in filenames.

572

573

Add new switch, <tt>wait-if-missing-keys</tt>, which requires the user

574

to acknowledge if keys are missing when defaulting to encryption.

575

576

Slightly reorganise configuration menu to keep it within 24 lines.

577

578

Update documentation re: crashes related to the second patch and

579

mailcap files.

580

581

Topal makes greater efforts to check that external commands exist

582

before running them.

583

584

Exception messages are repeated via Ada's exception handling (if Topal

585

panics).

586

587

Added <tt>decrypt-prereq</tt> option. See <a href="#decrypt-prereq">this note</a>.

588

589

Experimental S/MIME sending support added.

590

591

More use of GnuPG's <tt>--status-fd</tt> option so that we can determine exit

592

status properly.

593

594

Replaced ancient <tt>expanding_array</tt> package

595

with <tt>Ada.Containers.Vectors</tt>.

596

597

Adding sendmail-path filter mode. This is needed for the S/MIME

598

encrypted and S/MIME sign+encrypted modes. (Otherwise only Topal can

599

read them; neither Outlook nor Thunderbird will cope with an S/MIME

600

part inside multipart/mixed.) This mode also

601

needs <tt>pinentry-qt</tt>

602

for <tt>gpgsm</tt>: <tt>pinentry-curses</tt> doesn't like this environment.

603

604

In the sendmail-path filter mode, we no longer need the content-type

605

guessing. We can simply re-use the content-type from the original

606

header.

607

608

Added replace-ids option which can replace Message-ID (and also

609

Content-ID) in sendmail-path filter mode.

610

611

The sendmail-path mode can also add a token to help spot our cc'd

612

emails. Use something like <tt>st=user@domain,token</tt> to set a

613

password. This is hashed with some headers for each email and added

614

to an <tt>X-Topal-Send-Token</tt> header. Topal then has a <tt>-cst

615

token</tt> mode which adds a <tt>X-Topal-Check-Send-Token</tt>

616

header with either <tt>yes</tt> or <tt>no</tt> for that header.

617

618

Investigation suggests that group addresses are handled other than I

619

expect. E.g., <tt>Group name:;</tt> in the to: field and the actual

620

list of addresses in lcc field will result in the addresses appearing

621

in the bcc field in sendmail-path filter mode.

622

623

Rewrite main documentation in LaTeX: the main manual is

624

now <a href="topal.pdf"><tt>topal.pdf</tt></a>. The

625

<a href="Changelog.html">change log</a> is still in HTML.

626

627

Start adding interoperability notes to manual.

628

629

Diagnosing issue with clearsigned (both OpenPGP and S/MIME) emails

630

that have passed through an MS Exchange server being corrupted.

631

632

Added opaque signing option for S/MIME.

633

634

Added <tt>attachment-trap</tt> boolean option. In <tt>-asend</tt>

635

mode, this causes Topal to complain if the message body contains the

636

string “attach” but doesn't have any attachments.

637

</dd>

638

<dt><a name="last-changes"/>23/6/2011; release 74</a></dt><dd>

639

Oops, wrong year in release 73 date….

640

641

Topal needs GNAT's <tt>-gnat05</tt> switch.

642

643

Documentation update:<ul>

644

<li> Noted the need for GNU's sed (particularly

645

important if you're using

646

Mac OS X). </li>

647

<li> Noted that <tt>gpg-agent</tt> needs HUPing

648

if <tt>trustlist.txt</tt> is updated.

649

</li>

650

</ul>

651

652

Added <tt>include-send-token</tt> switch, where 1 never includes them,

653

2 asks and 3 always includes them.

654

655

Warnings about configuration errors now go to stderr, rather than

656

messing up other processing output.

657

658

Heuristic for attachment trap is improved. This now copes with the

659

case where the email comprises a single multipart/mixed MIME part.

660

661

Some comparisons for content-types are case-insensitive now.
