IERenderer ("IER") Version History


The download 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 below.

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My S/MIME extension is heavily outdated and should not be used anymore unless announced here otherwise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.

BTW: If you'd like to get the (Delphi) source code please let me know!

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

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

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

09.06.2010, 14:45 (CEST): Version 2.1.0.4

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

29.04.2010, 13:00 (CEST): Version 1.8.0.7

21.04.2010, 12:30 (CEST): Version 1.8.0.5

This version provides an enhanced error handling and several fixes inlcuding working around proxy related access restrictions.

11.04.2010, 13:00 (CEST): Version 1.8.0.3

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.

22.03.2010, 18:40 (CET): Version 1.5.2.0

This version provides some online help enhancements and fixes a W2K issue with the task bar.

13.03.2010, 13:30 (CET): Version 1.5.1.0

07.03.2010, 19:45 (CET): Version 1.5.0.3

This version fixes a zoom/resizing issue with IE 6.

04.03.2010, 22:30 (CET): Version 1.5.0.2

This version might fix a TER related crash when opening HTML attachments.

01.03.2010, 16:00 (CET): Version 1.5.0.1

This version just fixes a Unicode conversion issue when quoting selected text while replying to a formatted message.

01.03.2010, 20:00 (CET): Version 1.5.0.0

This version comes with lots of changes and enhancements:

Other changes in more or less chronological order (not listing the required user interface and help file adjustments):

  1. Adjustments and fixes for using the control with IE 6 (the last supported one on Windows 2000).
  2. Enhanced font sizing (actually zooming without modifying any font sizes) and mouse wheel support.
  3. Improved URL decoding and display including Punycode handling of IDNs and charset conversion fixes.
  4. Optional message header printing which only works when printing messages from a stand-alone reader window.
  5. Blacklist checks, fraud protection and redirection handling and some related adjustments with regard to scripts and frames warnings.

Please note that the latter features work a little different from the original BearHtml: All fraud and blacklist checking is only done when actually clicking a link. The reason for this is that it tries to resolve the fraudulent addresses for plausibility checks as I'm trying to avoid having to maintain another list of URLs like kept in the original BearWarn.txt.

When using innounp -x to unpack IERendererSetup.exe the IER files will be extracted to the following directories, here's where to put them:

Unpacker Screenshot

The fff-file in the fff-path location needs to contain the proper path to the location of IERenderer.dll (it usually doesn't need to be changed). Users of the German version need to rename the fff-file's extension to .fde or to add a respective copy along with it if they want to allow dual use.
