Podlove Publisher 2.6

Following up on our new policy to deliver new minor versions with (usually one) headline feature (along with necessary bug fixes) we are happy to announce the immediate availability of Podlove Publisher 2.6.

Please take notice that version 2.6 fixes a severe security bug in our code. So please update immediately. There are no earth-shattering changes in 2.6 that you should fear.

So what is new, you ask? Let’s see.

E-Mail Notifications

You might know this: podcasters recording with team mates and/or guests always tell everybody they will notify everybody once the new episode is available for download. But  somehow this check box is left unmarked after all the concentration went into the preparing the recording and finishing the publishing process. But why can’t this be done automatically?

Well, the time has come: if you upgrade to 2.6, you can enable the new “e-mail notifications” module.


Once enabled, you get an extra tab in your Podlove > Contributors menu called E-Mail Notifications.

Here you can specify which roles and/or groups of contributors you want to be notified by e-mail once the episode has been published and from which e-mail address this e-mail should be sent from (by selecting a contributor record). You can also specify a time delay so you can make sure the new episode has been successfully recognized by podcast directories, feed proxies and other elements in the cloud that usually delay the visibility of new episodes in podcast clients.


You can use the Podlove Templates language to craft your own e-mail content or just go with the default so you are addressing everybody properly. Please make sure you have configured a “contact e-mail address” which each contributor you expect to receive a notification.

This first release of this feature is intentionally designed very simple: there is one e-mail being sent for one configuration of people. Please let us know if this suits you or if you need this to be more flexible in the future.

Podlove Web Player 4 (Alpha)

We know everybody is waiting for our web player to advance. We too. We tried hard to deliver on that with our Player 3 prototype but eventually we found we were heading in the wrong direction and went back to the drawing board.

Publisher 2.6 is now coming with a new alpha (!) release of our upcoming release 4 of the Podlove Web Player. Please give it a try but DO NOT CONSIDER IT DONE. It is still work in progress. We made a a lot of progress already but we won’t consider it production ready until it is. But by trying it out and giving us feedback, we will get there sooner than later.

The Podlove Web Player 4 is coming in a new dress, provides player embedding (finally) and is prepared to deliver even more exciting things in the future. But for now just try it but don’t rely on it. We’ll talk much more about it when it’s ready.


You might still not care about our internal templating system but it’s pretty useful for some and for us it’s always a test for internal consistency as the template reflects our internal APIs and make things nicer for everybody.

We have put in some nice changes and enhancements in the way you can access and list podcast assets and feeds. Take a look at the detailed change log for more on this.

Other enhancements

We have updated a ton of little things here and there that make the UI more consistent and self-explanatory (we hope). Many small changes are also preparing the Publisher for more groundbreaking changes in the future that should make Publisher much easier to tame for casual podcasters and beginners.

For those who do not want to use the built-in Podlove Subscribe Button being loaded from the Podlove CDN (for organisational or other reasons) you can now tick a box so that the code gets loaded from your blog only. This also means updates to the buttons must come through updates to the Podlove Publisher. So when you use that option, make sure you update Publisher immediately when a new version comes out (which you should do anyway).

And even without updating you might have noticed already that Podlove Publisher now comes completely localized in German too. So if you have set your language to German in your WordPress backend, everything Publisher should be german now too.


Thanks to Eric Teubert for most new stuff in the Publisher and thanks to Alexander Heimbuch and Markus Stuhr for work on the new Podlove Web Player 4. We also say welcome back to Alexander Lüken who is again contributing to the Publisher. And finally, thanks to everyone who helped with the translation to German.

We hope you love the new changes and features. Spread the word and happy podcasting.

Podlove Publisher 2.5

We are excited to announce the immediate release of Podlove Publisher 2.5. Special thanks to Eric Teubert who has contributed 99% of this release and is constantly working on Podlove Publisher to make it the best tool possible.

The new release is mostly maintenance work and reworked features so there is not much that looks shiny and new at first glance but is more targeted to improve our overall architecture, get some historic awkwardness out of the way and prepare the Publisher for future features that are actually shiny and new.

There is one exception in terms of shinyness: the new chapters interface.


Chapter support has been at the core of the Publisher saga from the beginning. We always felt that structuring potentially long podcasts is a boon to both listeners and publishers and should be supported by the publishing system in first class way.

So we kicked off the Podlove Web Player with chapter navigation and put a feature into Podlove Publisher to upload a chapter file to the backend which can then be used to put chapter info into the player, the podcast feed (in PSC format for podcast apps and directories to consume) and also pass it along to optional backends like Auphonic.

When the Publisher started this, chapters were almost nonexistent in the podcast world. Today, there are thousands of podcasts making use of chapters and more and more podcast apps support chapter navigation. These numbers are going up continuously as podcasters find creation and delivery of chapters is getting more streamlined and as listeners understand that chapters make consuming and revisiting long and highly structured podcasts much easier.

However, we have neglected the backend interface for actually entering chapter information far too long. Until version 2.4 you had to provide chapters in the so-called mp4chapters format in pure form with additional error checking and metadata evaluation. No more: Podlove Publisher 2.5 has replaced the old crumpy way of doing things with a simple interface that actually supports more chapter file formats too.


This list presents chapters the way they should be. Each chapter displays its calculated duration and you can freely edit and delete individual chapters. So now you can use the Publisher’s backend to actually create the chapter information in an interactive fashion without using external tools.


We also support entering chapter URLs now.

If you want to maintain a file-based workflow you can of course still do that. Instead of copy-and-pasting the information into a simple text field you can now import the chapter file in one simple step:


Update: in Podlove Publisher 2.5.1 you can also import chapter information from Hindenburg project files.

If you have created your chapters in the backend but want to save it in a separate file we have also added a simple export function to write chapters to either a Podlove Simple Chapters file


And that’s it. The new interface should make life easier for those who already use chapters and should be an encouragement for those who haven’t looked into this. We can only recommend checking it out, it’s making podcasting better for everybody.

Other changes

Apart from the chapter feature we have tweaked a few minor things that were asking for change most of which you usually barely notice but might be worth knowing about.

Contributor Avatar Upload: You can now upload avatar images for your Contributors to the WordPress media library without referring to external URLs. This should have been possible for a long time and now it finally is. It’s another step in our march towards less external dependencies which will a get a larger update in the future.

Say goodbye to App.net: We were happy to jump on the bandwagon that was App.net years ago as it promised to be a fun way for podcasters to connect to listeners but alas ADN will shut down today forever so we have removed the ADN module from Podlove Publisher. So long and thanks for all the fish.

Background import and export: The importing and exporting routines could be become quite long as podcasts grow so they could take up so much time WordPress started to throw in some nasty timeouts and killed it off. Not good. So we have moved these routines to our new background processing system introduced in the last release and that should work reliably even for huge archives.

Background Jobs Dashboard: The dashboard is now updated in real time giving you the option to easily look at what’s going on in the Publishers machine room if you fancy that. It’s like watching a washing machine: maybe totally boring in the long run but might have a soothing effect on you. Who knows?

Redirect Counter Reset: If you are using Podlove Publishers built-in redirection module (in Expert Settings) – useful for domain and URL transitions – now you can not only see how many times an individual redirect has been used from outside, but you can also reset the counter now to make it easy to detect if the redirect is still needed. Small changes make people happy sometimes.

Future developments and support

If you think you might have seen more big features being put into a single release in the past you are right. We have decided to speed up things by focusing on a single big feature per each release now and to throw in some minor maintenance stuff too. Bug fixes will still be delivered on an as-needed basis for dot-dot-releases.

So stay tuned for more nice things from Podlove and please keep supporting us with donations. Donations have gone down quite significantly recently and we really need to cover some extra costs for meetings and travel of team members.

Another option is to get the direct Podlove Publisher Support. This way you are both contributing directly to development AND getting immediate technical support for your installation in case something goes wrong. While we have our eyes open in the Podlove Community for questions and troubles we might not always have the time and focus to help out when troubles arise. The professional support option takes care of that.

Thanks for everybody who has supported us so far.

New website for Podlove Subscribe Button

We have a set up a new informational and fancy looking website dedicated to the Podlove Subscribe Button. Have a look:


Apart from explaining what the button is about it also features a nifty new embed generator that makes adding the button to any website quick and easy.

In contrast to our more technical project page, that is addressing developers and other people interested in the tech behind, this new page is mainly aimed towards podcasters and is also a way to get the word out for podcast listeners who think our button is a good idea.

Please note that we have launched a similar website dedicated to the Podlove Publisher a few months ago that serves a similar purpose:


That site also highlights the primary benefits of the system and also highlights our support options. If you are benefitting from Podlove Publisher and please consider the support contract: it helps to pay for ongoing changes to the software and actively supports you when haunting for problems with your podcast.

Podlove Publisher 2.4

By: NY - http://nyphotographic.com/ CC BY-SA 3.0 NY

Podcast (By: NY – http://nyphotographic.com/) released under  CC BY-SA 3.0 NY

Good news everyone: Podlove Publisher 2.4 was released today.

Yeah, it’s been a while – but while development on Podlove Publisher was slow it was never coming to a halt. We have constantly improved little things, put some polish on existing features and added a bunch of stuff under the hood.

So we are happy to have 2.4 available to you now and want you to update as soon as possible. But please take a moment to read about the changes.

Background Jobs

There are significant changes to how the Publisher does things in the background. Most importantly, the whole subsystem on how background jobs are handled has been replaced with a new model that should be far more reliable for some environments and in particular for episode-rich podcasts. This is the basis for improvements done to the Publisher’s Analytics feature which was a focus for this new version.

New Analytics

Be aware that the new Analytics might bring some disappointments. We have used the time to review the system under half a year of real world use and have found that the Publisher was tricked into believing some traffic to be true download activity while it wasn’t. Turns out that those on the Dark Side™ are hitting all our servers with a lot of bots to find security holes. While we are not aware of any security breaches in our software, the Publisher did count many of these shady requests as legitimate download intents.

Well, no more. The downside is that after a quick recalculation (which will be kicked off automatically when upgrading), your statistics might look slightly more bleak than they did before. In our tests we experienced an up to 20% drop in the reported numbers. Sorry, not much we can do about that.

When releasing the Analytics feature we told you not to make too much out of these numbers as they need to pass the real world test. So here is the result of that. However, we are hopeful that you won’t see anything like this in future updates to the Publisher.

To compensate for this, we have improved that Analytics dashboard presenting the data in a much more meaningful way. Numbers are now presented in a cumulative way allowing for easy comparison of individual episodes. You can look at summaries on a daily basis for the first week, then weekly (for the first month), then monthly (for the first quarter), then quarterly (for the first year) and then yearly (up to three years). Not all of these columns will be visible immediately: just head up to the standard WordPress Screen Options on the top of the page to set your preferred viewing configuration.

podcast-clients-publisher-2-4The “Downloads per Day” chart on the top of the Dashboard should also be much clearer now, showing the top episodes downloaded in the recent two weeks. We have also updated the list of known Podcast Clients making the episode analytics more useful.

In addition to some global statistics being shown everything should also load MUCH faster than it did before as things are computed in the background now and cached for quick display.

Podlove Web Player 2.1

We have also included a fresh copy of the recently updated Podlove Web Player that received some technical and some visual updates to keep up with the fast pace of the Web. We have also added the Podigee Player to be used optionally if you prefer to do so.

New Tools menu

In order to make the Publishers UI more meaningful and easier to understand, we have created a new Tools page that contains helpful tasks that might be useful when things look stuck or confusing data is presented. We think these need to be invoked only every now and then or possibly never. But PHP web systems can get messy sometimes so we thought it’s better to have a toolbox ready to take action before having to rely on external support.


The logging section in the dashboard has always been confusing so we cleaned up the mess to make it more helpful. We moved it to the Support page (to make clear when you might want to use it at all) and added some filtering options when you want to look for past errors and warnings. More needs to be done in this area but hopefully these changes will be helpful already. We also dropped some messages that polluted the log file for no good reasons.

Moving to HTTPS

Moving web sites to HTTPS should be a no brainer, but doing this for podcasts has a caveat: for reasons unknown to intelligent beings on this planet the iTunes Podcast Directory still has weird limitations when dealing with HTTPS-enabled podcast web sites. While claiming having full HTTPS support in their backend Apple is effectively limiting iTunes to TLS certificates that are given out by a short list of apparently hand-picked providers on the Internet.

This rules out using the by far most popular and most recommendable approach on the net these days: getting a free and automatically renewing certificate from the great folks of Let’s Encrypt (read about this in this support thread). But also other certificates are excluded.

We have no clue why this limitation exists but it effectively prohibits many podcast sites from moving to HTTPS. Once feeds are delivered via HTTPS and do not meet the limited requirements of the iTunes Podcast Directory, new episodes will not show up for existing podcasts and new podcasts can’t even be submitted to the store. Ouch.

But Podlove is here to help. You can now configure your web site to use HTTPS for all pages EXCLUDING your feeds (everything under /feed) and Podlove Publisher 2.4 has a new expert setting that allows you to define this.

You can choose from the following settings:

* Don’t assume anything about the configuration (default)
* Website is run via HTTP only
* Website is run via HTTPS only
* Website is run via HTTPS (excluding feeds which use http)

Select your setup and Podlove Publisher will then do the right thing. The last option will make sure the feed URLs will be consistently displayed, delivered and redirected properly to make sure that iTunes can still access your podcast.

The iTunes FAQ says that HTTPS will “eventually be required”. Let’s hope they fix their handling of certificates before that time comes.

Goodbye, Feed Validator

We have dropped the external feed validation check with Feed Validator. While we generally think an external feed checker is a good thing, Feed Validator just didn’t cut it for us.

Not only did it (mistakingly) complain about Podlove’s (and other) name spaces being used. It also has a severe and problematic issue with the above mentioned migration towards HTTPS by not allowing URLs to use the https protocol scheme (although the original RSS 2.0 spec does not explicitly prohibit HTTPS to be used). So all https URLs were considered buggy. The team always resisted changing this behaviour so we have to remove it.

We might make use of newer validators Cast Feed Validator or Podbase in the future but for now we recommend you to do your checks with them manually to see if things are okay. Just don’t use Feed Validator anymore, it’s bad for podcasts and probably won’t ever change.

Other changes

We have fixed a ton of tiny bugs and added some niceties here and there to make us all happy including more meaningful defaults for new users, using the post’s featured image as an episode image, fyyd.de podcast directory integration and best of all: Emojis in titles and descriptions are no longer swallowed ????!


Podlove Publisher 2.4 does not change its system requirements and should just work when installed.

However, we strongly advise you to keep your WordPress and PHP version up to date all the time. Some features of the Podlove Publisher rely on WordPress being updated and you should always run the latest version just for security reasons alone.

Please note that PHP 5.4 and 5.5 (while still being supported by the Publisher) have RUN OF OUT OF SUPPORT. These versions no longer get any security updates potentially making your system easy to exploit by the bad guys. Please do take this seriously. The Podlove Publisher may also increase the minimum version of PHP at any time. An added benefit of this: the faster people move to current versions of PHP the easier it will to improve reliability and add new features as the latest versions bring a lot on the table developers really like (and need).

If security alone is not enough to convince you (although it should), pleas note that moving to PHP 5.6 will probably double the speed of your system and moving to PHP 7 WILL DOUBLE THAT once more. The result is a faster less resource-intensive web site which is always a good thing.

Podlove Web Player 2.1

Our Web Player has been a major breakthrough when it first surfaced in 2012 featuring a new approach to presenting podcasts on the web with the introduction of clickable chapter marks.

The initial work of Gerrit van Aaken was then quickly continued by Simon Waldherr in 2013 which brought the widget to a new level with a revamped UI adding more audio navigation and metadata features. Apart from some minor tweaks and fixes, Podlove Web Player 2 has been mostly unchanged ever since.

Behind the scenes we started thinking about and working on version 3 of the player trying to incorporate new ideas and a fresh UI. A beta version of this player sneaked in to release 2.3.4 of the Podlove Publisher but was never finalised. After some time, we found development is stuck in a dead end and so we have stopped development in favour of a new plan for a version 4 of the widget. This will take some time however.

In order to keep up with the ever evolving Web, we have decided to take care of the old code base for the time being and have updated the Podlove Web Player to version 2.1. Not much is changed however: we have updated the look on mobile devices to make better use of screen estate and have fixed some problems with outdated JavaScript libraries.

IMG 9968

Version 2.1 is available now in the standalone Podlove Web Player plugin for WordPress and will be included in the upcoming 2.4 release of the Podlove Publisher. Developers using the button in their code base might want to update via GitHub.

Depending on how the new project comes along we might or might not add additional tweaks to Web Player 2 but don’t hold your breath for major enhancements as the dog is too old to teach it new tricks.

WordPress Plugin for Podlove Subscribe Button updated

We have recently updated the Podlove Subscribe Button WordPress Plugin to version 1.3. It now supports more customization for selecting cover images and button language and should make life easier for podcasters who are not using the Podlove Publisher but want easy integration with our Subscribe Button.

Don’t be confused: this plugin is not the Subscribe Button itself. It is a helper plugin to properly and easily embed the Subscribe Button into any WordPress blog even if it is not publishing any podcasts.

Future versions of this plugin might add integration with other common podcast plugins so that meta data needs not to be entered manually. Stay tuned.

Thanks to Alex who mainly contributed to this update.

German Public Radio adopts Podlove Subscribe Button

1600x300 Deutschlandradio_HeaderbannerOur Podlove Subscribe Button has been adopted by Germany’s public radio Deutschlandradio which operates four national networks and is the undisputed leader in high quality radio programming in the German speaking world.

Podcast pages at Deutschlandfunk and Deutschlandradio Kultur are already featuring the button covering more than 100 public podcasts with more to come.

dlr-buttonsIn a blog post by Deutschlandradio Lab project leader Boris Bittner details the reasons for adopting the button including the PSB being open source, easy to use and easy to integrate and touting the hope that more public radio stations and private podcasters will follow its example sooner than later.

We have been supporting Deutschlandradio in this process and welcome anybody who wants to follow suit. Contact us if you have questions and/or suggestions and we are happy to help.

While Podlove was started with supporting the global independent podcast landscape in general we see great benefits for the public radio and free radio projects too. We want to keep the podcast market open and free from platform constraints and invite everybody to collaborate and team up with us to achieve this goal together.

About the Podlove Subscribe Button

The Podlove Subscribe Button (PSB) is Podlove’s approach to easily integrate podcasts with the web allowing listeners to quickly subscribe to podcast from the publishers’ own websites using their preferred podcast application or podcast cloud service. With just a few easy taps or clicks anybody can subscribe to the content they cherish and love without hassle or hindrance.

The PSB works with all popular operating systems and platforms and welcomes developers to jump onboard with just a few tiny and standard-conforming enhancements to their apps. Podcasters or podcast directory

Podlove will continue to enhance and evolve the button to cover all available apps and services, to improve the user experience even more and is planning to bring new features and updates to the button soon that will make it even more useful in the near future.

Software updates for using the Podlove Subscribe Button

We have recently told you about the new design of the Podlove Subscribe Button and we are happy to have collected mostly positive feedback since then. However, people also asked how to leverage the new features. Let’s talk bit more about that.

We have recently updated both the Podlove Publisher (2.3.12) and the dedicated Podlove Subscribe Button (1.2) WordPress plugins to show an expected set of controls to make use of the new button.

Both plugins provide a dedicated WordPress widget to easily include a button in the design of your choice in one of your sidebars. It also supports the new WordPress Customises enabling a live preview while changing the button’s properties:

Psb widget editor

If you are using the Podlove Publisher, the builtin widget is made for showing a subscribe button for your own podcast. As all the information about this is already known, you just have to take care of the shiny details of how the button should look like on your page.

The dedicated Podlove Subscribe Button plugin allows easy integration of the button for any podcast you have the necessary information for so you can show a button for other podcasts (or your own if you are not yet using the publisher).

I hope these updates serve you well and please don’t stop to provide feedback about the button. Use Twitter (@podlove_org) or our Podlove Community for questions and suggestions.

Podlove Subscribe Button: The Redesign

Since having launched the Podlove Subscribe Button (PSB) at the end of 2014, our one-stop solution for easily subscribing to Podcasts is already being used by more than 2000 podcasts on the web. And we have also got a lot of positive feedback by users and podcasters alike. So it seems subscribing to podcasts has become much easier for many podcast listeners out there – which is great!

Podcast directories and podcast hosting sites have also embraced the button as its integration in web pages of any kind is pretty easy to do. More and more podcast client developers have added the necessary hooks to their products so we have continously increased the number of apps supported by the PSB. If you are a podcast client developer and want to see your program listed in the PSB, please follow the guidelines on how to integrate and how to submit your app for inclusion to our team.

Customising the button

The Podlove Subscribe Button has always provided options for customisations. The button can present the podcast image along with it, comes in three sizes and can optionally adapt to the page size too. Of course, these features continues to exist.

However, some podcasters have complained about the particular design we chose for the button. Some disliked its 3D-style. Others wanted to customise the color or simply wanted more options to better adapt the look of the button to their web design. While we have always allowed for custom links to invoke the button for web developers, we have listened and now provide a completely revamped new look of the button with more options.

Let’s walk through the new options that make customising the visual appearance easy for everyone.

Flat Design

First and foremost we have moved from the traditional 3D-inspired look to a “flat” appearance that much better integrates into current web design trends. This change is immediate and applies to all buttons currently in use – as long as they use our recommended way of using the button by simply including our hosted solution.

(If you are using the button by hosting your own copy of the button, please make sure you are always using the latest version of the master branch on GitHub).

Subscribe button green


Apart from asking for a flat design, the number 1 on podcasters’ customisation wish list was color. The PSB by default comes in a distinct style of green that we considered friendly and welcoming.

But many wanted to appear the button in a primary color that define the overall style of their web page. So now we allow to just that: you choose a primary color and the button uses that and automatically calculates highlight tones for button states to match this color.

Subscribe button blue

Subscribe button red

Subscribe button yellow

Note how the button text color automatically adapts to the primary color and enables both dark and light colors to be chosen without creating conflicts.


Apart from distinct color schemes, some websites also have different styles of “lightness” where the standard “filled” button appearance seems to “heavy” when compared to other elements. So we have added to new styles to account for that.

The “outline” style removes the filling and provides a simple boxed version of the button. The “frameless” style removes the box completely and creates an even lighter look.

Subscribe buttons filled outline frameless

Square Button

We have provided both a “rectangle” and “cover” appearance from the start. New to the family is a “square” format that strips the description from the button and simply presents the generic podcast logo in the button. This should cover most design choices of web site and should allow inclusion of the button on every possible place.

Subscribe buttons square

Future enhancements

We will continue to enhance and evolve the Podlove Subscribe Button. Future developments might include manually selecting formats and provide local usage statistics. The exact list of features depends on the feedback of podcasters and users to please let us know what you think how everything should look and feel.

Feel free to drop feature requests, ideas or bug reports at the Podlove Community.

Thanks to Michaela and Ben for their contribution to make the redesign reality.
