| 8 These changes are listed in decreasing version number order. Note this can be | |
| 9 different from a strict chronological order when there are two branches in | |
| 10 development at the same time, such as 4.5.x and 5.0. | |

| 20 .. _changes_6-4-2: | |
| 21 | |
| 22 Version 6.4.2 — 2022-07-12 | |
| 23 -------------------------- | |
| 24 | |
| 25 - Updated for a small change in Python 3.11.0 beta 4: modules now start with a | |
| 26 line with line number 0, which is ignored. This line cannnot be executed, so | |
| 27 coverage totals were thrown off. This line is now ignored by coverage.py, | |
| 28 but this also means that truly empty modules (like ``__init__.py``) have no | |
| 29 lines in them, rather than one phantom line. Fixes `issue 1419`_. | |
| 30 | |
| 31 - Internal debugging data added to sys.modules is now an actual module, to | |
| 32 avoid confusing code that examines everything in sys.modules. Thanks, | |
| 33 Yilei Yang (`pull 1399`_). | |

| 41 Version 6.4.1 — 2022-06-02 | |
| 42 -------------------------- | |
| 43 | |
| 44 - Greatly improved performance on PyPy, and other environments that need the | |
| 45 pure Python trace function. Thanks, Carl Friedrich Bolz-Tereick (`pull | |
| 46 1381`_ and `pull 1388`_). Slightly improved performance when using the C | |
| 47 trace function, as most environments do. Closes `issue 1339`_. | |
| 48 | |
| 49 - The conditions for using tomllib from the standard library have been made | |
| 50 more precise, so that 3.11 alphas will continue to work. Closes `issue | |
| 51 1390`_. | |

| 60 | |
| 61 Version 6.4 — 2022-05-22 | |
| 62 ------------------------ | |
| 63 | |
| 64 - A new setting, :ref:`config_run_sigterm`, controls whether a SIGTERM signal | |
| 65 handler is used. In 6.3, the signal handler was always installed, to capture | |
| 66 data at unusual process ends. Unfortunately, this introduced other problems | |
| 67 (see `issue 1310`_). Now the signal handler is only used if you opt-in by | |
| 68 setting ``[run] sigterm = true``. | |
| 69 | |
| 70 - Small changes to the HTML report: | |
| 71 | |
| 72 - Added links to next and previous file, and more keyboard shortcuts: ``[`` | |
| 73 and ``]`` for next file and previous file; ``u`` for up to the index; and | |
| 74 ``?`` to open/close the help panel. Thanks, `J. M. F. Tsang | |
| 75 <pull 1364_>`_. | |
| 76 | |
| 77 - The timestamp and version are displayed at the top of the report. Thanks, | |
| 78 `Ammar Askar <pull 1354_>`_. Closes `issue 1351`_. | |
| 79 | |
| 80 - A new debug option ``debug=sqldata`` adds more detail to ``debug=sql``, | |
| 81 logging all the data being written to the database. | |
| 82 | |
| 83 - Previously, running ``coverage report`` (or any of the reporting commands) in | |
| 84 an empty directory would create a .coverage data file. Now they do not, | |
| 85 fixing `issue 1328`_. | |
| 86 | |
| 87 - On Python 3.11, the ``[toml]`` extra no longer installs tomli, instead using | |
| 88 tomllib from the standard library. Thanks `Shantanu <pull 1359_>`_. | |
| 89 | |
| 90 - In-memory CoverageData objects now properly update(), closing `issue 1323`_. | |

| 102 | |
| 103 Version 6.3.3 — 2022-05-12 | |
| 104 -------------------------- | |
| 105 | |
| 106 - Fix: Coverage.py now builds successfully on CPython 3.11 (3.11.0b1) again. | |
| 107 Closes `issue 1367`_. Some results for generators may have changed. | |
| 108 | |

| 111 | |
| 112 .. _changes_632: | |
| 113 | |
| 114 Version 6.3.2 — 2022-02-20 | |
| 115 -------------------------- | |
| 116 | |
| 117 - Fix: adapt to pypy3.9's decorator tracing behavior. It now traces function | |
| 118 decorators like CPython 3.8: both the @-line and the def-line are traced. | |
| 119 Fixes `issue 1326`_. | |
| 120 | |
| 121 - Debug: added ``pybehave`` to the list of :ref:`coverage debug <cmd_debug>` | |
| 122 and :ref:`cmd_run_debug` options. | |
| 123 | |
| 124 - Fix: show an intelligible error message if ``--concurrency=multiprocessing`` | |
| 125 is used without a configuration file. Closes `issue 1320`_. | |
| 126 | |
| 127 .. _issue 1320: https://github.com/nedbat/coveragepy/issues/1320 | |

| 132 | |
| 133 Version 6.3.1 — 2022-02-01 | |
| 134 -------------------------- | |
| 135 | |
| 136 - Fix: deadlocks could occur when terminating processes. Some of these | |
| 137 deadlocks (described in `issue 1310`_) are now fixed. | |
| 138 | |
| 139 - Fix: a signal handler was being set from multiple threads, causing an error: | |
| 140 "ValueError: signal only works in main thread". This is now fixed, closing | |
| 141 `issue 1312`_. | |
| 142 | |
| 143 - Fix: ``--precision`` on the command-line was being ignored while considering | |
| 144 ``--fail-under``. This is now fixed, thanks to | |
| 145 `Marcelo Trylesinski <pull 1317_>`_. | |
| 146 | |
| 147 - Fix: releases no longer provide 3.11.0-alpha wheels. Coverage.py uses CPython | |
| 148 internal fields which are moving during the alpha phase. Fixes `issue 1316`_. | |
| 149 | |

| 157 | |
| 158 Version 6.3 — 2022-01-25 | |
| 159 ------------------------ | |
| 160 | |
| 161 - Feature: Added the ``lcov`` command to generate reports in LCOV format. | |
| 162 Thanks, `Bradley Burns <pull 1289_>`_. Closes issues `587 <issue 587_>`_ | |
| 163 and `626 <issue 626_>`_. | |
| 164 | |
| 165 - Feature: the coverage data file can now be specified on the command line with | |
| 166 the ``--data-file`` option in any command that reads or writes data. This is | |
| 167 in addition to the existing ``COVERAGE_FILE`` environment variable. Closes | |
| 168 `issue 624`_. Thanks, `Nikita Bloshchanevich <pull 1304_>`_. | |
| 169 | |
| 170 - Feature: coverage measurement data will now be written when a SIGTERM signal | |
| 171 is received by the process. This includes | |
| 172 :meth:`Process.terminate <python:multiprocessing.Process.terminate>`, | |
| 173 and other ways to terminate a process. Currently this is only on Linux and | |
| 174 Mac; Windows is not supported. Fixes `issue 1307`_. | |
| 175 | |
| 176 - Dropped support for Python 3.6, which reached end-of-life on 2021-12-23. | |
| 177 | |
| 178 - Updated Python 3.11 support to 3.11.0a4, fixing `issue 1294`_. | |
| 179 | |
| 180 - Fix: the coverage data file is now created in a more robust way, to avoid | |
| 181 problems when multiple processes are trying to write data at once. Fixes | |
| 182 issues `1303 <issue 1303_>`_ and `883 <issue 883_>`_. | |
| 183 | |
| 184 - Fix: a .gitignore file will only be written into the HTML report output | |
| 185 directory if the directory is empty. This should prevent certain unfortunate | |
| 186 accidents of writing the file where it is not wanted. | |
| 187 | |
| 188 - Releases now have MacOS arm64 wheels for Apple Silicon, fixing `issue 1288`_. | |

| 201 | |
| 202 .. _changes_62: | |
| 203 | |
| 204 Version 6.2 — 2021-11-26 | |
| 205 ------------------------ | |
| 206 | |
| 207 - Feature: Now the ``--concurrency`` setting can now have a list of values, so | |
| 208 that threads and another lightweight threading package can be measured | |
| 209 together, such as ``--concurrency=gevent,thread``. Closes `issue 1012`_ and | |
| 210 `issue 1082`_. | |
| 211 | |
| 212 - Fix: A module specified as the ``source`` setting is imported during startup, | |
| 213 before the user program imports it. This could cause problems if the rest of | |
| 214 the program isn't ready yet. For example, `issue 1203`_ describes a Django | |
| 215 setting that is accessed before settings have been configured. Now the early | |
| 216 import is wrapped in a try/except so errors then don't stop execution. | |
| 217 | |
| 218 - Fix: A colon in a decorator expression would cause an exclusion to end too | |
| 219 early, preventing the exclusion of the decorated function. This is now fixed. | |
| 220 | |
| 221 - Fix: The HTML report now will not overwrite a .gitignore file that already | |
| 222 exists in the HTML output directory (follow-on for `issue 1244`_). | |
| 223 | |
| 224 - API: The exceptions raised by Coverage.py have been specialized, to provide | |
| 225 finer-grained catching of exceptions by third-party code. | |
| 226 | |
| 227 - API: Using ``suffix=False`` when constructing a Coverage object with | |
| 228 multiprocessing wouldn't suppress the data file suffix (`issue 989`_). This | |
| 229 is now fixed. | |
| 230 | |
| 231 - Debug: The ``coverage debug data`` command will now sniff out combinable data | |
| 232 files, and report on all of them. | |
| 233 | |
| 234 - Debug: The ``coverage debug`` command used to accept a number of topics at a | |
| 235 time, and show all of them, though this was never documented. This no longer | |
| 236 works, to allow for command-line options in the future. | |
| 237 | |
| 238 .. _issue 989: https://github.com/nedbat/coveragepy/issues/989 | |
| 239 .. _issue 1012: https://github.com/nedbat/coveragepy/issues/1012 | |
| 240 .. _issue 1082: https://github.com/nedbat/coveragepy/issues/1082 | |
| 241 .. _issue 1203: https://github.com/nedbat/coveragepy/issues/1203 | |
| 242 | |
| 243 | |
| 244 .. _changes_612: | |
| 245 | |
| 246 Version 6.1.2 — 2021-11-10 | |
| 247 -------------------------- | |
| 248 | |
| 249 - Python 3.11 is supported (tested with 3.11.0a2). One still-open issue has to | |
| 250 do with `exits through with-statements <issue 1270_>`_. | |
| 251 | |
| 252 - Fix: When remapping file paths through the ``[paths]`` setting while | |
| 253 combining, the ``[run] relative_files`` setting was ignored, resulting in | |
| 254 absolute paths for remapped file names (`issue 1147`_). This is now fixed. | |
| 255 | |
| 256 - Fix: Complex conditionals over excluded lines could have incorrectly reported | |
| 257 a missing branch (`issue 1271`_). This is now fixed. | |
| 258 | |
| 259 - Fix: More exceptions are now handled when trying to parse source files for | |
| 260 reporting. Problems that used to terminate coverage.py can now be handled | |
| 261 with ``[report] ignore_errors``. This helps with plugins failing to read | |
| 262 files (`django_coverage_plugin issue 78`_). | |
| 263 | |
| 264 - Fix: Removed another vestige of jQuery from the source tarball | |
| 265 (`issue 840`_). | |
| 266 | |
| 267 - Fix: Added a default value for a new-to-6.x argument of an internal class. | |
| 268 This unsupported class is being used by coveralls (`issue 1273`_). Although | |
| 269 I'd rather not "fix" unsupported interfaces, it's actually nicer with a | |
| 270 default value. | |

| 280 | |
| 281 Version 6.1.1 — 2021-10-31 | |
| 282 -------------------------- | |
| 283 | |
| 284 - Fix: The sticky header on the HTML report didn't work unless you had branch | |
| 285 coverage enabled. This is now fixed: the sticky header works for everyone. | |
| 286 (Do people still use coverage without branch measurement!? j/k) | |
| 287 | |
| 288 - Fix: When using explicitly declared namespace packages, the "already imported | |
| 289 a file that will be measured" warning would be issued (`issue 888`_). This | |
| 290 is now fixed. | |
| 291 | |
| 292 .. _issue 888: https://github.com/nedbat/coveragepy/issues/888 | |
| 293 | |
| 294 | |
| 295 .. _changes_61: | |
| 296 | |
| 297 Version 6.1 — 2021-10-30 | |
| 298 ------------------------ | |
| 299 | |
| 300 - Deprecated: The ``annotate`` command and the ``Coverage.annotate`` function | |
| 301 will be removed in a future version, unless people let me know that they are | |
| 302 using it. Instead, the ``html`` command gives better-looking (and more | |
| 303 accurate) output, and the ``report -m`` command will tell you line numbers of | |
| 304 missing lines. Please get in touch if you have a reason to use ``annotate`` | |
| 305 over those better options: ned@nedbatchelder.com. | |
| 306 | |
| 307 - Feature: Coverage now sets an environment variable, ``COVERAGE_RUN`` when | |
| 308 running your code with the ``coverage run`` command. The value is not | |
| 309 important, and may change in the future. Closes `issue 553`_. | |
| 310 | |
| 311 - Feature: The HTML report pages for Python source files now have a sticky | |
| 312 header so the file name and controls are always visible. | |
| 313 | |
| 314 - Feature: The ``xml`` and ``json`` commands now describe what they wrote | |
| 315 where. | |
| 316 | |
| 317 - Feature: The ``html``, ``combine``, ``xml``, and ``json`` commands all accept | |
| 318 a ``-q/--quiet`` option to suppress the messages they write to stdout about | |
| 319 what they are doing (`issue 1254`_). | |
| 320 | |
| 321 - Feature: The ``html`` command writes a ``.gitignore`` file into the HTML | |
| 322 output directory, to prevent the report from being committed to git. If you | |
| 323 want to commit it, you will need to delete that file. Closes `issue 1244`_. | |
| 324 | |
| 325 - Feature: Added support for PyPy 3.8. | |
| 326 | |
| 327 - Fix: More generated code is now excluded from measurement. Code such as | |
| 328 `attrs`_ boilerplate, or doctest code, was being measured though the | |
| 329 synthetic line numbers meant they were never reported. Once Cython was | |
| 330 involved though, the generated .so files were parsed as Python, raising | |
| 331 syntax errors, as reported in `issue 1160`_. This is now fixed. | |
| 332 | |
| 333 - Fix: When sorting human-readable names, numeric components are sorted | |
| 334 correctly: file10.py will appear after file9.py. This applies to file names, | |
| 335 module names, environment variables, and test contexts. | |
| 336 | |
| 337 - Performance: Branch coverage measurement is faster, though you might only | |
| 338 notice on code that is executed many times, such as long-running loops. | |
| 339 | |
| 340 - Build: jQuery is no longer used or vendored (`issue 840`_ and `issue 1118`_). | |
| 341 Huge thanks to Nils Kattenbeck (septatrix) for the conversion to vanilla | |
| 342 JavaScript in `pull request 1248`_. | |

| 355 | |
| 356 Version 6.0.2 — 2021-10-11 | |
| 357 -------------------------- | |
| 358 | |
| 359 - Namespace packages being measured weren't properly handled by the new code | |
| 360 that ignores third-party packages. If the namespace package was installed, it | |
| 361 was ignored as a third-party package. That problem (`issue 1231`_) is now | |
| 362 fixed. | |
| 363 | |
| 364 - Packages named as "source packages" (with ``source``, or ``source_pkgs``, or | |
| 365 pytest-cov's ``--cov``) might have been only partially measured. Their | |
| 366 top-level statements could be marked as unexecuted, because they were | |
| 367 imported by coverage.py before measurement began (`issue 1232`_). This is | |
| 368 now fixed, but the package will be imported twice, once by coverage.py, then | |
| 369 again by your test suite. This could cause problems if importing the package | |
| 370 has side effects. | |
| 371 | |
| 372 - The :meth:`.CoverageData.contexts_by_lineno` method was documented to return | |
| 373 a dict, but was returning a defaultdict. Now it returns a plain dict. It | |
| 374 also no longer returns negative numbered keys. | |

| 384 | |
| 385 - In 6.0, the coverage.py exceptions moved from coverage.misc to | |
| 386 coverage.exceptions. These exceptions are not part of the public supported | |
| 387 API, CoverageException is. But a number of other third-party packages were | |
| 388 importing the exceptions from coverage.misc, so they are now available from | |
| 389 there again (`issue 1226`_). | |
| 390 | |
| 391 - Changed an internal detail of how tomli is imported, so that tomli can use | |
| 392 coverage.py for their own test suite (`issue 1228`_). | |
| 393 | |
| 394 - Defend against an obscure possibility under code obfuscation, where a | |
| 395 function can have an argument called "self", but no local named "self" | |
| 396 (`pull request 1210`_). Thanks, Ben Carlsson. | |

| 405 Version 6.0 — 2021-10-03 | |
| 406 ------------------------ | |
| 407 | |
| 408 - The ``coverage html`` command now prints a message indicating where the HTML | |
| 409 report was written. Fixes `issue 1195`_. | |
| 410 | |
| 411 - The ``coverage combine`` command now prints messages indicating each data | |
| 412 file being combined. Fixes `issue 1105`_. | |
| 413 | |
| 414 - The HTML report now includes a sentence about skipped files due to | |
| 415 ``skip_covered`` or ``skip_empty`` settings. Fixes `issue 1163`_. | |
| 416 | |
| 417 - Unrecognized options in the configuration file are no longer errors. They are | |
| 418 now warnings, to ease the use of coverage across versions. Fixes `issue | |
| 419 1035`_. | |
| 420 | |
| 421 - Fix handling of exceptions through context managers in Python 3.10. A missing | |
| 422 exception is no longer considered a missing branch from the with statement. | |
| 423 Fixes `issue 1205`_. | |
| 424 | |
| 425 - Fix another rarer instance of "Error binding parameter 0 - probably | |
| 426 unsupported type." (`issue 1010`_). | |
| 427 | |
| 428 - Creating a directory for the coverage data file now is safer against | |
| 429 conflicts when two coverage runs happen simultaneously (`pull 1220`_). | |
| 430 Thanks, Clément Pit-Claudel. | |

| 440 .. _changes_60b1: | |
| 441 | |
| 442 Version 6.0b1 — 2021-07-18 | |
| 443 -------------------------- | |
| 444 | |
| 445 - Dropped support for Python 2.7, PyPy 2, and Python 3.5. | |
| 446 | |
| 447 - Added support for the Python 3.10 ``match/case`` syntax. | |
| 448 | |
| 449 - Data collection is now thread-safe. There may have been rare instances of | |
| 450 exceptions raised in multi-threaded programs. | |
| 451 | |
| 452 - Plugins (like the `Django coverage plugin`_) were generating "Already | |
| 453 imported a file that will be measured" warnings about Django itself. These | |
| 454 have been fixed, closing `issue 1150`_. | |
| 455 | |
| 456 - Warnings generated by coverage.py are now real Python warnings. | |
| 457 | |
| 458 - Using ``--fail-under=100`` with coverage near 100% could result in the | |
| 459 self-contradictory message :code:`total of 100 is less than fail-under=100`. | |
| 460 This bug (`issue 1168`_) is now fixed. | |
| 461 | |
| 462 - The ``COVERAGE_DEBUG_FILE`` environment variable now accepts ``stdout`` and | |
| 463 ``stderr`` to write to those destinations. | |
| 464 | |
| 465 - TOML parsing now uses the `tomli`_ library. | |
| 466 | |
| 467 - Some minor changes to usually invisible details of the HTML report: | |
| 468 | |
| 469 - Use a modern hash algorithm when fingerprinting, for high-security | |
| 470 environments (`issue 1189`_). When generating the HTML report, we save the | |
| 471 hash of the data, to avoid regenerating an unchanged HTML page. We used to | |
| 472 use MD5 to generate the hash, and now use SHA-3-256. This was never a | |
| 473 security concern, but security scanners would notice the MD5 algorithm and | |
| 474 raise a false alarm. | |
| 475 | |
| 476 - Change how report file names are generated, to avoid leading underscores | |
| 477 (`issue 1167`_), to avoid rare file name collisions (`issue 584`_), and to | |
| 478 avoid file names becoming too long (`issue 580`_). | |

| 491 | |
| 492 Version 5.6b1 — 2021-04-13 | |
| 493 -------------------------- | |
| 494 | |
| 495 Note: 5.6 final was never released. These changes are part of 6.0. | |
| 496 | |
| 497 - Third-party packages are now ignored in coverage reporting. This solves a | |
| 498 few problems: | |
| 499 | |
| 500 - Coverage will no longer report about other people's code (`issue 876`_). | |
| 501 This is true even when using ``--source=.`` with a venv in the current | |
| 502 directory. | |
| 503 | |
| 504 - Coverage will no longer generate "Already imported a file that will be | |
| 505 measured" warnings about coverage itself (`issue 905`_). | |
| 506 | |
| 507 - The HTML report uses j/k to move up and down among the highlighted chunks of | |
| 508 code. They used to highlight the current chunk, but 5.0 broke that behavior. | |
| 509 Now the highlighting is working again. | |
| 510 | |
| 511 - The JSON report now includes ``percent_covered_display``, a string with the | |
| 512 total percentage, rounded to the same number of decimal places as the other | |
| 513 reports' totals. | |

| 519 .. _changes_55: | |
| 520 | |
| 521 Version 5.5 — 2021-02-28 | |
| 522 ------------------------ | |
| 523 | |
| 524 - ``coverage combine`` has a new option, ``--keep`` to keep the original data | |
| 525 files after combining them. The default is still to delete the files after | |
| 526 they have been combined. This was requested in `issue 1108`_ and implemented | |
| 527 in `pull request 1110`_. Thanks, Éric Larivière. | |
| 528 | |
| 529 - When reporting missing branches in ``coverage report``, branches aren't | |
| 530 reported that jump to missing lines. This adds to the long-standing behavior | |
| 531 of not reporting branches from missing lines. Now branches are only reported | |
| 532 if both the source and destination lines are executed. Closes both `issue | |
| 533 1065`_ and `issue 955`_. | |
| 534 | |
| 535 - Minor improvements to the HTML report: | |
| 536 | |
| 537 - The state of the line visibility selector buttons is saved in local storage | |
| 538 so you don't have to fiddle with them so often, fixing `issue 1123`_. | |
| 539 | |
| 540 - It has a little more room for line numbers so that 4-digit numbers work | |
| 541 well, fixing `issue 1124`_. | |
| 542 | |
| 543 - Improved the error message when combining line and branch data, so that users | |
| 544 will be more likely to understand what's happening, closing `issue 803`_. | |

| 557 Version 5.4 — 2021-01-24 | |
| 558 ------------------------ | |
| 559 | |
| 560 - The text report produced by ``coverage report`` now always outputs a TOTAL | |
| 561 line, even if only one Python file is reported. This makes regex parsing | |
| 562 of the output easier. Thanks, Judson Neer. This had been requested a number | |
| 563 of times (`issue 1086`_, `issue 922`_, `issue 732`_). | |
| 564 | |
| 565 - The ``skip_covered`` and ``skip_empty`` settings in the configuration file | |
| 566 can now be specified in the ``[html]`` section, so that text reports and HTML | |
| 567 reports can use separate settings. The HTML report will still use the | |
| 568 ``[report]`` settings if there isn't a value in the ``[html]`` section. | |
| 569 Closes `issue 1090`_. | |
| 570 | |
| 571 - Combining files on Windows across drives now works properly, fixing `issue | |
| 572 577`_. Thanks, `Valentin Lab <pr1080_>`_. | |
| 573 | |
| 574 - Fix an obscure warning from deep in the _decimal module, as reported in | |
| 575 `issue 1084`_. | |
| 576 | |
| 577 - Update to support Python 3.10 alphas in progress, including `PEP 626: Precise | |
| 578 line numbers for debugging and other tools <pep626_>`_. | |

| 591 | |
| 592 Version 5.3.1 — 2020-12-19 | |
| 593 -------------------------- | |
| 594 | |
| 595 - When using ``--source`` on a large source tree, v5.x was slower than previous | |
| 596 versions. This performance regression is now fixed, closing `issue 1037`_. | |
| 597 | |
| 598 - Mysterious SQLite errors can happen on PyPy, as reported in `issue 1010`_. An | |
| 599 immediate retry seems to fix the problem, although it is an unsatisfying | |
| 600 solution. | |
| 601 | |
| 602 - The HTML report now saves the sort order in a more widely supported way, | |
| 603 fixing `issue 986`_. Thanks, Sebastián Ramírez (`pull request 1066`_). | |
| 604 | |
| 605 - The HTML report pages now have a :ref:`Sleepy Snake <sleepy>` favicon. | |
| 606 | |
| 607 - Wheels are now provided for manylinux2010, and for PyPy3 (pp36 and pp37). | |
| 608 | |
| 609 - Continuous integration has moved from Travis and AppVeyor to GitHub Actions. | |

| 617 | |
| 618 Version 5.3 — 2020-09-13 | |
| 619 ------------------------ | |
| 620 | |
| 621 - The ``source`` setting has always been interpreted as either a file path or a | |
| 622 module, depending on which existed. If both interpretations were valid, it | |
| 623 was assumed to be a file path. The new ``source_pkgs`` setting can be used | |
| 624 to name a package to disambiguate this case. Thanks, Thomas Grainger. Fixes | |
| 625 `issue 268`_. | |
| 626 | |
| 627 - If a plugin was disabled due to an exception, we used to still try to record | |
| 628 its information, causing an exception, as reported in `issue 1011`_. This is | |
| 629 now fixed. | |
