NB: Please uninstall previous versions of IERenderer
via Windows Control Panel before downgrading!

IERenderer ("IER") Version History

The downloaddownload archive (for Pegasus Mail 4.61 or later only!) provides an installer along with this history.
If you've got issues with using the installer you may want to try Inno Unpacker, for usage instructions see down below.

NB: If downloading the installer from this page and launching it on Windows 10 or later with Windows Defender enabled
it may prompt you with its so called SmartScreen. For understanding why this happens and what would be required
to get rid of it even for open source developers please take a look at this article.
To continue updating your current version of IERenderer please click as indicated by the following screenshots.

SmartScreen screenshot

If still having issues you may try any of these suggestions:

Users of my encryption extension PMPGP should upgrade to its latest version
before using the new renderer as they may encounter crashes and weird display issues otherwise.
My S/MIME extension is heavily outdated and should not be used anymore unless announced here otherwise
since I haven't been able to further maintain it for the last couple of years, I'm sorry.
Pegasus Mail v5 will be able to provide native support for S/MIME, though.

27.06.2023 21:45 (CEST): Version 2.7.1.0

This time there's a preface required about the enhanced image handling applied to (clipboard) copies of messages, replies and forwards: Please note that it still doesn't work in all cases even with embedded pictures although if opened in browsers it would: There's always the final step of conversion from HTML to RTF to be done by Pegasus Mail's HTS/TER modules which I can only control so far by preparing the input to some limited extent: If inserting copies of SVG images (e.g.) as part of a HTML snippet into LibreOffice you'd get better results than in Pegasus Mail since RTF doesn't support this type of images and the converter I'm using only deals with part of its capabilities.
I'm either not fully applying this feature to replies and forwards with downloaded remote pictures because it would slow down message preparation and loading into the editor to an extent not appropriate for email processing IMO. If you still want to try it out you may use the clipboard for copying and pasting such messages containing lots of remote pictures (it actually even appears to work faster for unknown reasons). And there's another limitation: It all depends on having caching enabled and opened such messages with images displayed at least once in reader or preview before pictures can be embedded into copies, replies and forwards. This is true even for embedded pictures, please keep this in mind before feeling you're missing something!

17.05.2023 02:15 (CEST): Version 2.7.0.7

25.04.2023 03:30 (CEST): Version 2.7.0.6

24.11.2022 01:15 (CET): Version 2.6.6.4

Sorry for this one: It fixes a crash occurring on Win 10 (at least, Win7 not being affected) when opening messages in Pegasus Mail's stand-alone reader window (preview not being affected) when switching from formatted (HTML) to plain text.

22.11.2022 08:30 (CET): Version 2.6.6.3

This version just fixes a non-ASCII character conversion failure occurring when pasting characters from this range (such as © or ®) into Pegasus Mail's editor after conversion from formatted HTML to plain text. You may test it now using the sample characters provided in this announcement, they should even display properly in any of the addressing lines if copied from your various browsers ...

21.11.2022 02:30 (CET): Version 2.6.6.2

11.10.2022 00:45 (CEST): Version 2.6.6.0

01.08.2022 03:30 (CEST): Version 2.6.5.18

This update mostly provides fixes and enhancements for a couple of user interface issues which have been bugging me for some time but took a while to make it up to the top of the priority list, here they finally come:

30.06.2022 06:00 (CEST): Version 2.6.5.17

27.06.2022 06:00 (CEST): Version 2.6.5.16

05.03.2022 05:00 (CET): Version 2.6.5.10

More or less sorted by importance/urgency after the Pegasus Mail v4.8 release:

14.02.2022 07:00 (CET): Version 2.6.5.9

There was a pretty stupid last minute fault, sorry ...

14.02.2022 06:00 (CET): Version 2.6.5.8

02.02.2022 03:00 (CET): Version 2.6.5.7

12.01.2022 03:15 (CET): Version 2.6.5.6

10.01.2022 05:30 (CET): Version 2.6.5.5

07.01.2022 02:45 (CET): Version 2.6.5.4

30.12.2021 06:00 (CET): Version 2.6.5.3

Woa, forgot to rephrase the redirection dialog to the requested rewording of the confirmation - and took the chance to decrease the font for the paragraph about the error codes.

30.12.2021 04:00 (CET): Version 2.6.5.2

24.12.2021 22:30 (CET): Version 2.6.5.1

Well, just some quick fixes/enhancements for the imminent Pegasus Mail release:

21.12.2021 09:20 (CET): Version 2.6.5.0

Several news about this version for Pegasus Mail 4.8, so here's the most important stuff:

21.10.2021 03:15 (CEST): Version 2.6.4.33

This version just fixes an issue with the IER's blank message warning detected immediately after the previous release which fortunately wouldn't have affected any rendering issues but degrade error handling convenience.

21.10.2021 01:30 (CEST): Version 2.6.4.32

This version is exclusively about fixing minor issues, annoyances of and enhancing error handling in several places plus hopefully fixing some crashes and hangs under certain conditions some of which I could only duplicate on WinXP.

27.09.2021 02:00 (CEST): Version 2.6.4.31

03.09.2021 01:00 (CEST): Version 2.6.4.30

13.08.2021 04:00 (CEST): Version 2.6.4.28

This version just fixes retrieval of inline pictures using content IDs containing hierarchical URL paths.

13.08.2021 01:00 (CEST): Version 2.6.4.27

03.08.2021 06:00 (CEST): Version 2.6.4.26

27.07.2021 05:00 (CEST): Version 2.6.4.25

26.07.2021 02:00 (CEST): Version 2.6.4.24

23.07.2021 15:15 (CEST): Version 2.6.4.22

21.07.2021 03:30 (CEST): Version 2.6.4.21

16.07.2021, 03:00 (CEST): Version 2.6.4.20

07.07.2021, 02:00 (CEST): Version 2.6.4.19

This version just fixes the crash of the previous one occurring when launching Pegasus Mail with IER on Windows versions without the MS Edge browser installed (i.e. almost exclusively prior to Windows 10).

06.07.2021, 03:30 (CEST): Version 2.6.4.18

04.06.2021, 01:00 (CEST): Version 2.6.4.17

This version provides a rewrite of the (inline & remote) image request, download and error handling routines which have recently been challenged by different issues regarding addressing and fetching "innovations" and errors causing IER to not display graphics properly or even at all. Most of these issues could be fixed while for the remaining ones an enhanced error display is provided on Pegasus Mail's status bar at its bottom left edge.

17.05.2021, 02:00 (CEST): Version 2.6.4.16

And yes, we did it again (whoever the other ones are ;-)): It was only a couple of hours after the previous release that I got a message which wouldn't allow to display its inline graphics for no obvious reasons. And it unfortunately took me an awful lot of time to figure out that it wasn't a coding issue causing this but a simple misdeclaration of the graphics file type which made IE's renderer stumble while Mozilla's Gecko simply ignored it and displayed what it found instead of (nothing) what it claimed to be. So here's the version that double checks such claims from now on and provides the proper file extension if required to fix this originator issue.

15.05.2021, 14:30 (CEST): Version 2.6.4.15

07.05.2021, 01:00 (CEST): Version 2.6.4.13

21.04.2021, 03:30 (CEST): Version 2.6.4.12

20.04.2021, 03:00 (CEST): Version 2.6.4.11

19.04.2021, 01:30 (CEST): Version 2.6.4.10

09.04.2021, 18:00 (CEST): Version 2.6.4.9

This update just provides an adjustment of IER's file version detection for dealing with Pegasus Mail's beta versions.

09.04.2021, 03:00 (CEST): Version 2.6.4.8

19.03.2021, 02:30 (CET): Version 2.6.4.7

17.03.2021, 02:00 (CET): Version 2.6.4.6

22.02.2021, 23:00 (CET): Version 2.6.4.4

23.01.2021, 00:00 (CET): Version 2.6.4.2

05.01.2021, 20:45 (CET): Version 2.6.4.1

Once again here's a quick fix for something I actually had already prepared but didn't finish because of who knows what: The dialog occasionally displaying warnings about suspect hyperlinks which caused the access violations fixed with the previous release didn't work properly when clicking the Ok button. This hasn't only been fixed but does now even provide the browser drop-down list known from the reader context menu if applicable.

04.01.2021, 00:45 (CET): Version 2.6.4.0

21.12.2020, 06:00 (CET): Version 2.6.3.14

Well, once again there had to be some kind of an "emergency fix" regarding the adjustment of the default Rich Text font to become Pegasus Mail's default editor font if pasting in formatted quotes, so here it is without modifying the pasted text now. Sorry for this one.

20.12.2020, 22:45 (CET): Version 2.6.3.13

24.11.2020, 01:30 (CET): Version 2.6.3.12

This version just fixes the browser context menu launch issue accidentally introduced with the enhanced error handling of the previous version. :-/

23.11.2020, 02:30 (CET): Version 2.6.3.11

23.10.2020, 02:00 (CEST): Version 2.6.3.10

This update is all about wasting lots of time in figuring out and fixing a Windows 10 issue with not displaying RTF popups providing options help the same way as all previous Windows versions did ever since ...

22.10.2020, 14:30 (CEST): Version 2.6.3.9

29.06.2020, 00:00 (CEST): Version 2.6.3.8

This version should finally fix the infinite loop issue.

26.06.2020, 22:30 (CEST): Version 2.6.3.7

16.06.2020, 23:00 (CEST): Version 2.6.3.6

03.04.2020, 15:00 (CEST): Version 2.6.3.5

This version is all about fixing the issue of the browser selection popup submenu not appearing on right mouse button clicks for some users for unknown reasons: It's finally solved and hopefully without any unwanted side effects!

21.03.2020, 19:30 (CET): Version 2.6.3.4

21.02.2020, 21:00 (CET): Version 2.6.3.3

24.01.2020, 00:00 (CET): Version 2.6.3.2

16.01.2020, 22:30 (CET): Version 2.6.3.1

Forgot to reenable faster rendering for messages that don't need the extra treatment of the Instagram workaround - fixed now.

15.01.2020, 23:00 (CET): Version 2.6.3.0

15.10.2019, 00:30 (CEST): Version 2.6.2.12

This is just the recompiled previous version signed with a new self-signed certificate (RSA 4096 SHA 512).

10.10.2019, 22:00 (CEST): Version 2.6.2.11

09.10.2019, 20:30 (CEST): Version 2.6.2.10

06.10.2019, 20:00 (CEST): Version 2.6.2.9

24.09.2019, 20:00 (CEST): Version 2.6.2.8

This version is once again supposed to fix the image display issue by fixing CSS file handling and disabling another IE feature called "FEATURE_MIME_SNIFFING".

24.09.2019, 01:30 (CEST): Version 2.6.2.7

This version only fixes the reader pane's link context menu for copying images and selecting browsers working again.

22.09.2019, 15:00 (CEST): Version 2.6.2.6

17.09.2019, 22:00 (CEST): Version 2.6.2.5

08.09.2019, 20:00 (CEST): Version 2.6.2.3

This version just provides the updated help files that should have been provided with the previous version.

This version just provides the updated help files that should have been provided with the previous version.

24.08.2019, 13:00 (CEST): Version 2.6.2.2

This version adds more data to Pegasus Mail's viewer.pm file which controls the file extensions of attached files passed to any application or module supposed to deal with message attachments such as Pegasus Mail's HTML renderers and external viewers. This is one of the sources for IER to append proper file extensions to image files being loaded by IERenderer in those cases where it doesn't appear to do it without those anymore for currently unknown reasons.

23.08.2019, 21:00 (CEST): Version 2.6.2.1

14.08.2019, 17:00 (CEST): Version 2.6.2.0

14.07.2019, 20:00 (CEST): Version 2.6.1.0

27.06.2019, 18:00 (CEST): Version 2.6.0.0

28.05.2019, 23:00 (CEST): Version 2.5.1.0

05.04.2019, 23:30 (CEST): Version 2.5.0.1

This version only fixes a crash occuring when trying to print HTML messages with headers included (and hopefully doesn't break anything else).

03.04.2019, 20:00 (CEST): Version 2.5.0.0

This time there are several major enhancements aside from the usual fixes:

29.03.2018, 19:00 (CEST): Version 2.4.10.3

11.08.2016, 23:00 (CEST): Version 2.4.9.13

This version fixes a zoom issue affecting only systems with IE versions less than 9.

26.07.2016, 22:30 (CEST): Version 2.4.9.12

24.03.2015, 13:00 (CET): Version 2.4.9.9

This version adds a DOCTYPE declaration to tidied HTML solving some display issues.

03.02.2015, 20:15 (CET): Version 2.4.9.8

28.12.2013, 20:00 (CET): Version 2.4.9.0

05.12.2013, 21:15 (CET): Version 2.4.8.1

05.12.2013, 18:30 (CET): Version 2.4.8.0

29.05.2013, 14:00 (CEST): Version 2.4.7.10

30.12.2012, 14:30 (CET): Version 2.4.7.6

This version provides workarounds for several kinds of broken image source URLs. Please note, that this doesn't necessarily result in proper image display, it may just ensure faster processing and error display if applicable.

30.05.2010, 13:00 (CEST): Version 2.1.0.0

This version's main work was done on migrating the source code to an up-to-date development environment requiring lots of adjustments especially with regard to string handling (Unicode). The new code includes several minor fixes and enhancements as well, of course.

15.05.2010, 20:30 (CEST): Version 2.0.0.0

06.04.2010, 22:30 (CEST): Version 1.8.0.0

29.03.2010, 16:30 (CEST): Version 1.5.3.0

Aside from some minor fixes (including proper handling of background images) this version provides fixes and enhancements of the fraud checking feature: It tries to exclude file extensions from being checked as long as they aren't also used as TLDs by using the respective IANA WHOIS Service . I've also added a very pronounced warning against disabling the Load WinSock option as fraud and blacklist checking (and image downloads, of course) heavily depend on its proper functioning.
