+This release contains a major configuration change, updating the URL of the

+`archive.org` (#833, @pkgw). The new default URL is:

-[gh-releases]: https://github.com/tectonic-typesetting/tectonic/releases
+https://relay.fullyjustified.net/default_bundle.tar
+
+This switch was motivated by the recent breakage caused by a change in
+archive.org's internal implementation, even though that breakage has been fixed
+in the most recent release of the `tectonic_geturl` crate. The `archive.org`
+redirection service has always had low-level reliability issues and, more
+importantly, is blocked in China, which is a fatal issue for a potentially large
+number of users.
+
+The new webservice is a very simple nginx server set up in a Docker container
+defined in the [tectonic-relay-service] repo. The associated web infrastructure
+runs on Microsoft Azure and is configured using Terraform files in the
+[tectonic-cloud-infra] repo.

+# tectonic_bundles 0.1.0 (2021-06-15)
+
+Add the `tectonic_bundles` crate! This separates out the implementation of the
+various Tectonic file “bundles” into a standalone crate, so that you can use
+them without having to link to harfbuzz and everything else pulled in by the
+main crate.
+
+As usual, separating out this crate led to some good API clarifications and
+improvements. The API offered here includes some nontrivial breakage compared to
+the old APIs in `tectonic::io::*`, but it's much more rationalized.

-- Update redirection logic to unbreak archive.org resolution (#832, @pkgw). The
-  Internet Archive PURL service added a new layer of indirection through the URL
-  `https://purl.prod.archive.org/net/pkgwpub/tectonic-default`, which had an
-  unfortunate interaction with logic in Tectonic intended avoid pursuing
-  redirections into S3-type hashed storage services. That logic stopped
-  resolution when the final element of the URL path (i.e. the filename) did not
-  contain a period character. This used to be fine when the base archive.org URL
-  redirected directly to the configured destination URL, but stopped too soon
-  with the new indirection layer. The logic has been updated to also continue
-  pursuing the redirection if the filename of the new URL matches the filename
-  of the original URL, which avoids the issue in this case and seems generally
-  reasonable.
-- Related to the above, the new archive.org redirection used an HTTP status code
-  of 307, which is a slightly more fully-specified version of the 302 status
-  code. While the redirection code accepted a final status code of 302
-  (indicating that it decided to stop resolving URLs, i.e., it thinks that it
-  has reached the edge of an S3-type hashed storage service), it did not accept
-  a 307 result. Now it does (#832, @pkgw). Note that if this behavior had been
-  in place before, Tectonic would not have broken with the new archive.org
-  update, but the behavior would have been somewhat incorrect: the URL
-  resolution would have stopped too soon. But given the semantic similarity of
-  302 and 307, if we allow the former, we should allow the latter.
-
-These fixes are, however, effectively superseded because the release of Tectonic
-that contains them will also contain an update of the default URL to a new
-dedicated service (`relay.fullyjustified.net`), since `archive.org` is sometimes
-unreliable and is blocked in China.

+# tectonic_io_base 0.3.0 (2021-06-15)
+
+- Add new "abspath" methods to the IoProvider trait. We need a new API to
+  generate proper SyncTeX output in the XeTeX engine, and this is the best
+  approach that we could devise that does a good job of maintaining backwards
+  compatibility. However, implementors of the IoProvider trait that delegate to
+  inner implementations will need to make sure to explicitly implement the new
+  methods in order to provide correct behavior (#762).
+- Add a new `app_dirs` module for system-wide knowledge of per-user directories
+  (@pkgw, #768). It's valuable to put this low in the dependency stack so that
+  higher-level crates can just "know" where to go for per-user files such as the
+  bundle cache.
+- Correct some broken internal links in the docs.
+
+
+# tectonic_io_base 0.2.0 (2021-06-03)
+
+- BREAKING: use `&str` for TeX paths rather than `OsStr`. In principle this
+  prevents users from asking the TeX engine to load up files whose names aren't
+  expressible in Unicode, but that whole use case really meshes poorly with
+  Tectonic's goal to provide a portable, uniform user experience. And using
+  `str` just makes many parts of life much easier.
+- Expose a new interface for TeX path normalization.
+- If an engine requests to open a file from a filesystem provider, and that name
+  exists but is a directory, pretend that it's not found. This is sensible behavior
+  and prevents some hard-to-understand failures (#754)
+- Add `FilesystemIo::root()` for users that want to query the root directory of
+  a filesystem I/O provider.
